# PipeWire 0.3.39 (2021-10-21) This is a bugfix release that is API and ABI compatible with previous 0.3.x releases. ## Highlights - media-session is now moved into a separate module to speed up its deprecation in favour of WirePlumber. - There is now an LD_PRELOAD v4l2 emulation library to run some existing v4l2 applications on top of PipeWire. - Filter-chains should now flush out remaining samples when paused. There is now also the option to let a filter-chain drain so that long filters such as reverbs can fade out properly. - Stability and compatibility improvements in JACK apps. - Better Bluetooth compatibility with more devices. - libcamera plugin improvements. - Many bugfixes and improvements all over the map. ## PipeWire - Fix compilation on ARM. - Log topics are added to most modules. - Documentation updates. Many improvements to the layout. Reorganisation of the modules and groups. - Share a work queue for all links and nodes. This removes the need for a separate eventfd per link and per node. - Catch errors in the map implementation. - Add option to compile without dbus support. - Fix biquad frequency. It was using the wrong sample rate. - Fix a potential crash when destroying nodes, in some cases the node would not be deactivated properly. - Add some more helpers for dealing with properties and their values. - Implement flush and reset on virtual sinks/sources. - Make it possible to let virtual sinks/filter-chains run and drain after being idle. - Fix a bug where the quantum could exceed the maximum because it was scaled with the sample rate. - Fix channel_map parsing in module-zeroconf-discover so that the remote channel map is used. - pw-stream errors emitted on the proxy are reported but not fatal any more. They are usually used by the session manager to signal status to the client but otherwise does not really cause an error on the client. - Links now also store the output and input node id in the global properties so that applications can parse and use them regardless of how the link was made. (#1723) - pw-stream and pw-filter now have an event to notify commands. - The echo-cancel module can now operate on larger quantums. - pw-cat now uses the right metadata to find the default devices in --list-targets. ## media-session - Don't try to remix unpositioned streams when linking. This ensures that linking to Pro-Audio nodes does not remix the stream channels but links them as they are, one by one. - media-session is now moved to a separate module to accelerate its deprecation in favour of WirePlumber. ## SPA - Many libcamera improvements, handle MemFd buffers, handle errors gracefully. - Small improvements to make interface fall-backs easier to implement. - Add support to enable flush-to-zero and denormals-are-zero to avoid high CPU usage when dealing with denormals. - AUX13 channels are no longer reported as AUX12. (#1727) - Devices with more than 32 channels in Pro-Audio mode now only uses AUX channels. - Improve windowing function of the resampler to reduce aliasing and improve the quality. ## JACK - Port connect callbacks will not only be emitted after the port has negotiated buffers, which improves compatibility with applications that try to use the port right after the callback (jack_midi_latency_test). - Fix crash when midi ports were removed and being monitored, like in Ardour. ## pulse-server - The pulse tunnel will now use the specified format/rate/channels. - Improve lookup of default source and fall back to the monitors when no sources are available. - Mark some nodes as network nodes so that we can set the NETWORK flag correctly. ## GStreamer - The GStreamer element not releases the buffers in the stream again in all cases so that they can be reused by other streams. ## v4l2 - Add a v4l2 LD_PRELOAD library to emulate v4l2 system calls on top of PipeWire. This is tested with firefox and GStreamer and is known to not work with Chrome. ## Bluetooth - AAC compatibility improvements. - Disable hardware volume for "Tribit MAXSound Plus" and "SoundCore mini". - Add quirk to disable faststream. Disable faststream on "FiiO BTR3". - Add a dummy AVRCP player to improve compatibility with some devices. Older versions: # PipeWire 0.3.38 (2021-09-30) This is a quick bugfix release that is API and ABI compatible with previous 0.3.x releases. ## Highlights - Topic based logging was added to improve debugging. - An off-by-one error was fixed in the audio resampler that could cause distortion when downsampling. - Various bluetooth compatibility improvements. - More fixes and improvements. ## PipeWire - module-pulse-tunnel now has better default latency to make it work better in more cases. There is also an option to configure the desired latency. - pw-cli now has readline support. - Topic based logging was added. Log lines can now be filtered by topic using wildcards. This should improve debugging. - The systemd service files should now have better descriptions. - Fix a crash in module-zeroconf-discover when unloading. - Fix a crash in filter-chain when using unaligned memory. ## ALSA - Sync the udev rules and profiles with pulseaudio. - Fix a memory leak. ## SPA plugins - An off-by-one error was fixed in the resampler that could cause distortion when downsampling.

This fixes some long startup times. - Fix the kernel version check, 5.14.x kernels should also support mSBC. - Fix FastStream microphone support in more cases. - Add workaround for Intel AX200. - SCO sink should now also work in follower mode. ## PulseAudio server - Make the service file require a session manager. # PipeWire 0.3.37 (2021-09-23) This is a quick bugfix release that is API and ABI compatible with previous 0.3.x releases. ## Highlights - Capture and playback is now avoided even more on unavailable devices. This should fix some issues where an unusable microphone was selected by default. It should now also again be possible to select an unavailable device as the default. - Native DSD audio playback is now supported. pw-cat can now also play DSF files with the -d option. - JACK stability improvements with buffer-size and samplerate changes in some apps. - Many cleanups and bugfixes all over the place. ## PipeWire - pw-metadata -d does not cause an infinite loop anymore. (#1622) - Increase some plugin buffer sizes to fix some issues with many channels. (#1620) - Protect the global plugin list with a lock. Make sure pw_init() is locked. Fixes some issues with concurrent ALSA plugin usage. ## media-session - Unavailable devices can be set as the default again. (#1624) - Do a better check if a device has available routes and avoid selecting devices with unavailable routes as default. - Media-session was moved to its own directory. It used to live in examples but it is past the example stage and it interferes with the build options for the real examples. ## Bluetooth - The hardware quirk database is now loaded by the plugin instead of the session manager. This makes it also work with wireplumber. ## ALSA - The ALSA mixer now handles device removal much better. (#1627) ## libcamera - Many fixes and improvement to the libcamera plugin. (#1513) ## pulse-server - Improve compatibility with pulseaudio module arguments. - Parse channel_map arguments in module-loopback. (#1486) ## JACK - Delay emitting the samplerate and buffersize callbacks until the client is active. This fixes some crashes with Carla and other JACK apps. # PipeWire 0.3.36 (2021-09-16) This is a quick bugfix release that is API and ABI compatible with previous 0.3.x releases. ## Highlights - A quick update with mostly only bugfixes and small improvements. - Capture and playback is now avoided on unavailable devices. This should fix some issues where an unusable microphone was selected by default. - MIDI output should not stop randomly now. - The GStreamer elements are much improved, cheese should work a lot better now. - Virtual sinks and sources should now always show up immediately. - JACK processing is now delayed until buffersize and samplerate are emitted. This should improve stability of many JACK apps. - JACK transport sync is now implemented correctly so that preroll in bitwig works. ## PipeWire - The module dir environment variable can now contain multiple paths. - Documentation now contains dot graphs of dependencies. (#1585) - config min/max/default quantum values are now scaled with the samplerate. - A potential crash was fixed where destroyed memory was still used by a node. This could cause crashes in cheese. ## pipewire-media-session - Only allow passthrough for passthrough formats (S/PDIF) for now. (#1587) - Improve bluetooth profile autoswitch. - Don't try to route audio to nodes with unavailable routes. ## ALSA - Pass the right AES bits to the alsa device when opening an S/PDIF stream. - Fix a bug in the MIDI bridge port management logic. When a port was added and immediately removed, output would stop. ## GStreamer - The GStreamer source now handles the flushing state correctly. - All blocking operations now have a 30 seconds timeout, to avoid infinite locks. ## Plugins - V4l2 Device formats and controls are now passed on the node, just like with audio devices. - audioconvert now also exposes the softMute property. ## JACK - Improve stability when changing buffer size and sample rate dynamically by pausing the processing until the application has handled the callback. - Improve handling of timebase master. When the master was moved to another driver, it did not attempt to become a new timebase master on the new driver. (#1589) - Implement transport sync to make preroll in bitwig work. (#1589) ## pulse-server - Fix an issue where virtual sinks/sources would not show up immediately. (#1588) # PipeWire 0.3.35 (2021-09-09) This is a bugfix release that is API and ABI compatible with previous 0.3.x releases. ## Highlights - S/PDIF passthrough over optical or HDMI is now implemented. - Some critical fixes to MIDI, draining of streams and various modules. - skypeforlinux should work better now after adding it to the quirks database. - Bluetooth codecs are now in separate plugins to make it easier to ship them. ## PipeWire - Drain was fixed in pw-stream. In some cases it would not clear the drain state correctly. Fixes the issue where speaker-test would only play one channel. - Loopback connections to a driver will now activate the driver. This fixes an issue where MIDI connections between devices or some applications (puredata) would not get any MIDI messages. (#1559) - The audiomixer can now mix more formats. Together with the passthrough improvements this can be used to avoid conversions to/from the DSP format in some cases. - Make sure we idle drivers when removing a node from it in all cases. JACK clients could keep a driver node busy. - Add new methods to accumulate object info. The old one was difficult to use when applications need to accumulate multiple changes. - A new interface to load modules has been added. Plugins can use this to ask the host (PipeWire) to load spa plugins. - Increase param buffer size to handle larger params. Nodes with a large number of channels would sometimes not have properties. (#1574) - Concurrent link negotiation that caused some links to not work, is now avoided. This fixes monitor ports in Ardour6. - Small tweaks to how the quantum and rate are handled when nodes move between drivers. Make node.lock-quantum work with node.latency ## PipeWire modules - The convolver plugin in filter-chain has been optimized some more. - The echo-cancel stream properties were improved so that it actually can remember the streams it links to. (#1557) - module-pulse-tunnel had the buffer attributes wrong and would cause high latency with older pulseaudio servers. (#1434) - module-roc had the properties configured wrongly, which would cause it to not work at all in most cases. (#1538) - There is now an example of a 7.1 virtual surround sink using the hesuvi impulse responses. - The convolver now supports dirac pulses as the IR. ## ALSA - UCM config is now cached per device, using up less memory. It also temporarily works around a problem in alsa-lib that is now being patched and rolled out. Should stop devices from disappearing when logging out and back in. (#1553) - Fix the MIDI clock rate matching. It was too sensitive to small changes and would spiral out of control and break MIDI rather quickly. ## pipewire-media-session - The media session can now save and restore IEC958 (S/PDIF) codecs for the sinks. - Passthrough of IEC958 (S/PDIF) content is now possible. If the client and the sink contain a compatible set of codecs, an exclusive connection can be made between client and sink to pass the encoded S/PDIF content directly to the device. - Use new introspection info update methods to suspend nodes in all cases. Sometimes, nodes would fail to suspend because the state info was not evaluated. - The media session can now work in non-DSP mode, which will try to avoid any audio conversions between client and device when possible. But, this will also disable compatibility with JACK applications. ## Bluetooth - Bluetooth codecs are now compiled into separate plugins which are dynamically loaded. This makes it possible to change the plugin implementation or ship plugins separately without having to recompile the bluetooth module. ## PulseAudio server - Delay stream create reply until the stream is linked to a sink/source. - The device-restore extension is now implemented. This makes it possible to configure the IEC958 (S/PDIF) codecs supported by the sink with pavucontrol. - skypeforlinux now uses the same quirks as teams to make the sinks show up in all cases. This fixes the issue of not being able to hear the remote end in skypeforlinux. ## JACK - Improve catia and carla compatibility by caching objects a little longer after being removed. (#1531) - JACK ports now notify the negotiated format correctly. - A potential deadlock was fixed when multiple threads would perform a call that would require a roundtrip. - Improve bufsize callback, it should not be called right after doing activate() but only when the buffersize changes later. - Add tweak to disable the process lock. Some older apps might not expect it. (#1576) ## Docs - man pages are now generated with rst2man. - DMA-BUF docs were updated. - Documentation updates. # PipeWire 0.3.34 (2021-08-26) This is a bugfix release that is API and ABI compatible with previous 0.3.x releases. ## Highlights - Fixes some critical issues with previous release. Such as devices not showing up and default devices being lost. - Support for consumer driver streams to make the producer v-sync to the consumer monitor in a headless compositor setup. - Improvements to routing of streams. - Bluetooth battery status support for head-set profile and using Apple extensions. aptX-LL and FastStream codec support was added. - Internal latency of ALSA devices can now be configured. - A fast convolver was added to the filter-chain to implement virtual surround sinks or reverbs. ## PipeWire - Add support for streams that are driver nodes for the graph. This was already possible for source streams but it is now also possible for playback streams. This can be used to let a producer v-sync to the consumer monitor in a headless compositor setup. (#1484) - State files are now stored in XDG_STATE_HOME instead of XDG_CONFIG_HOME. They will still be loaded from the config home if they are not in the new state home, to ease migration. - Set a driver on inactive nodes to make transport work in xjadeo. (#1491) - Fix parsing of filter-chain controls. - A new FFT based convolver was added to module-filter-chain. It uses a 0-latency 2 stage convolver with small FFT for the head and a large FFT for the tail of the convolution. A convolution can be used to implement IR based reverbs, HRIR surround sound or other convolution based operations. An example HRIR virtual surround sound sink has been added as well. - module-filter-chain was reworked a bit to support more config options for the plugins. - Endian conversion and alaw/ulaw formats are now supported for streams. - pw-cat will now suggest a samplerate for the graph. - SPA_PLUGIN_DIR can now search in multiple paths separated with a ':'. - Passthrough mode has been worked on and has been partially merged. S/PDIF definitions have been added and ALSA devices updated to report and configure S/PDIF formats. The session manager changes to fully configure and enable passthrough mode will hopefully be merged next time. - Fix a race in pw-stream where it would not always emit the right events. ## ALSA - Fix volume changed check. It was checking against the wrong value and this could cause rounding errors. - The ALSA plugin now also uses RT scheduling. - Fix the behringer UMC202 usb device id, it was using a generic TI chip ID that caused problems. - Fix USB devices that don't show up anymore. Use an ALSA workaround to fix this. (#1478) - Add a rule for the new firmware of Sennheiser GSX 1200. - ALSA sink and source can now use ProcessLatency param to configure the internal latency. The latencyOffsetNsec property is also exposed so that the latency can be adjusted in pavucontrol as well. ## media-session - Fix a critical issue where the default device was not remembered anymore when it was removed. - Fix the issue where some apps need to be restarted when nodes go away and reappear. - Improve routing of streams. Streams that have a specific target set will now be moved to the target when it appears instead of staying on the fallback. - Small memory leak fixes. - Try to switch back to the user selected profile after finishing a Bluetooth recording. ## Bluetooth - Add support for HF indicator 2 battery status. - Add support for XAPL battery status. - Set the Communication intended role for HFP profile. - Enable SBC-XQ by default if not disabled by quirks. - Fix some potential crashes due to excessive polling. - Add aptx-LL codec and enable duplex for aptx-LL devices. - Add FastStream codec. This is a codec that can use a duplex SBC channel. ## PulseAudio server - Suggests a samplerate for the graph. - Support for handling S/PDIF (IEC958) formats was added. This will start working when the session manager supports configuring streams and nodes in passthrough mode. - Be smarter when handling devices without a negotiated format yet so that they are visible as well. This makes virtual devices show up immediately. ## ALSA plugin - Now suggests a samplerate for the graph. ## JACK - The jack.pc file can only be generated with meson >= 0.59.0. When the jack-devel option is enabled, it will generate an error with older meson. - Small stability improvements when connecting/disconnecting in Ardour. # PipeWire 0.3.33 (2021-08-05) This is a bugfix release that is API and ABI compatible with previous 0.3.x releases. ## Highlights - Better support for virtual sinks/sources for Pro Audio profile. - Better DMA-BUF format modifier negotiation. - Support multiple sample rates in the graph. Not enabled by default yet. - Bluetooth can now automatically switch between headset and audio profile. - Documentation updates. - Many improvements and crasher fixes. ## PipeWire - Make AUX channels an official channel map, use this for the PRO audio profile so that we can name the channels. This make it possible to define virtual sources and sinks for Pro Audio devices in a more reliable way. - Fix scheduling of some virtual sinks/sources. (#1407) - Fix potential corruption of ringbuffer because of multiple concurrent writers. This might be the cause for many reported crashes. (#1451) - Don't place sockets in $HOME. (#1443) - Improve DMA-BUF negotiation. Add a flag to avoid fixation of a property so that producers can negotiate more efficiently. This is used to negotiate DMA-BUF modifiers, which should make more efficient use of the GPU. (#1084) - Add support for multiple sample rates. The graph can switch when IDLE to one of the supported rates. Add an option to lock the rate as well. This is not enabled by default yet because of driver bugs that need to be worked around first. - Add node.lock-quantum property that can be used to lock the quantum in place. - Improve latency reporting in the loopback module. - Make new client-node method to send the peer port id to the mixer. This can be used to know where the buffers entering the mixer are coming from. (#1471) ## Tools - pw-top should now also correctly show bluetooth devices. (#1540) ## media-session - Handle unset of the default node. - Added a module that can switch the bluetooth profile to headset profile when a stream wants to record from it. ## JACK - Only call the jack callbacks when the client is active. Some JACK applications don't expect callbacks before the client is active and crash (x42-dpl).

(#1395) - Fix some memory leaks when destroying a card object. ## JACK - Fix some invalid cycle wakeups that could cause JACK application to run with a 0 buffer size. (#1386) - JACK can now use rtkit to manage realtime priorities on threads. - The Real-time priority is dropped when entering freewheel mode to make sure we don't get killed when using too much CPU. - jack_recompute_total_latencies() is now implemented, fixing the latency reporting in Ardour. (#1388) - Fix some overflows in time calculations. - Ensure frame_rate in position is never 0. - Graph callbacks are now emitted as well. ## Bluetooth - RTP payload type is now set correctly for aptX, LDAC and SBC, which should improve compatibility with devices that care about this. ## PulseAudio server - There is now a quirks database to deal with bad clients. The database is builtin but can be made external later. - Teams is now lied to and told all sink/sources use s16 samples to make it show all sinks/sources. - Firefox is forced to remove the DONT_MOVE flag on capture streams so that you can move firefox streams with other tools. - The UNDERFLOW warnings are now made into info log messages to not spam the log too much. Many application just let things underrun and PulseAudio did not warn about this either. (#910) ## ALSA plugin - The alsa plugin now uses the right metadata for finding the default source and sink, which makes the volume controls reappear. (#1384) ## Other - Cleanups in pulse-server and pipewire. - Documentation additions. # PipeWire 0.3.31 (2021-06-28) This is a bugfix release that is API and ABI compatible with previous 0.3.x releases. ## Highlights - Fixes for alsa-lib 1.2.5 - New pulseaudio modules: module-avahi-zeroconf, module-pipe-source, module-roc-sink, module-roc-source. - JACK has seen massive stability improvements.

Settings are now remembered per application or media-role. - The session manager remembers the last device used per stream - Fix a bug when moving streams where it could sometimes end up with linking a stream to multiple devices. - Use RTKit to set realtime priority on the data thread in the session manager. This improves performance of the pulse-server and bluetooth devices. - Add a new property to mark streams that want to capture from the monitor of the default sink. - NODE_TARGET can now also contain the node name. This avoids some lookups in the pulseaudio layer when selecting target nodes by name. - the -e and -d options are more usable now and can be used to add and remove modules from the default list of modules. - Device support - v4l2: add some workarounds for buggy drivers. Add Limited support for droidcam. - ACP: improve selection of default port and profiles. - ACP: add support for using the hardware mixer for more than 8 channel streams. - ACP: support the new port type and availability group found in PulseAudio. - A2DP bluetooth timings were reworked. Automatic linking of A2DP sources was added to make it possible for PipeWire to act as a bluetooth receiver. The code was reworked to allow other codecs such as APTX and LDAC in the future. - Try harder to recover from ALSA errors. - GStreamer improvements - Fix some crashes in the monitor that cause gnome-initial-setup to crash. - PulseAudio layer improvements - Many compatibility improvements. Improved playback in chrome. Fix a crash in firefox when the daemon is stopped. - Fix a leak in the formats. - Fix !ADJUST_LATENCY streams like paplay. - Make the device option in paplay work. - Fix volume/mute notifications, this makes plasma volume updates work again. - Do the conversion between PulseAudio cubic volumes and PipeWire linear volumes. Volume levels should behave now like they did with PulseAudio. - JACK layer improvements - Return an error when we run out of midi events. Some application rely on this behaviour. - ALSA plugin improvements - The ALSA plugin now also supports the node name in the playback_node and capture_node properties. PipeWire 0.3.13 This is a bugfix release that is API and ABI compatible with previous 0.3.x releases. - PipeWire improvements - Add pw-reserve tool to reserve or monitor a device on DBus. - Install spa-resample, a tool to resample a file. - Install spa-acp-tool, a tool to inspect the card profile. - Various fixes and improvements - Fix a bug in pw-stream where a capture stream could run out of buffers and become silent. - Rework the processing loops in the adapter and stream. There is now less latency in PulseAudio and ALSA layers. - Session manager improvements - Improve the device reservation code. We now try to acquire the device using the dbus device reservation API before we probe the device. This avoids conflicts with a running PulseAudio where devices would disappear (because they were locked by the other process). - Don't fail on invalid input from the config files. - Audio devices now have the same name as what PulseAudio would assign. - Device support - v4l2: try to use the format before enumerating the size and framerate. Some drivers don't check the format and might now work better. - v4l2: Fall back to MMAP when EXPBUF fails. Fix MMAP access, just export the fd and the mapoffset. This should make more devices work. - Fix crash in ALSA Card Profile (ACP) code. - ACP: fix selection of default profile. Prefer any possibly available profile over 'Off'. This makes some card at least start with something. - Fix soft volume. After setting the volume to 0, it would stay at 0 until pushed over the max volume. This should fix various volume related issues. - PulseAudio layer improvements - Rework the buffering and latency measurements and tweak the buffer attributes. This should make browsers and media players work better. This should also improve speechd performance. - JACK layer improvements - Fix compilation against newer JACK. PipeWire 0.3.12 This is a bugfix release that is API and ABI compatible with previous 0.3.x releases. - PipeWire improvements * the channelmap converter now handles unknown and strange channellayouts much better. * the resampler is now cleared correctly, avoiding clicks and pops at the start of sound. * Fixes for various crasher bugs. (paplay drain, vlc shutdown, pactl info, ...) * Fix a race condition in the node state changes that caused all kinds of sync and other issues (vlc, mpv, ...) * Improve the binary name property of applications * Fix the scheduling again of nodes that always need a driver such as the jack clients. - Session manager improvements * fix routing to default nodes. Sometimes nodes were not routed to the default node (bluetooth) - Device support * disable channelmap from ALSA by default. This is what PulseAudio does and thus provides better compatibility. * fix a bug in how the resampler was used in the ALSA source, causing distortion and errors when using low latency capture clients. (Discord, webrtc, ...) * Small bluetooth improvements. More work is needed for reliable bluetooth playback. - GStreamer plugins * the device provider now stops the processing loop before shutting down, which avoids crashes (gnome-initial-setup). - PulseAudio layer improvements * the buffer attributes were reworked to ensure compatibility with many more applications such as mpv and audacious. * the pulseaudio layer will now try hard to not hand out invalid channel maps to the application. (avoids crashes in gnome-volume-control). The channel map will now also look more like what PulseAudio does. * the @DEFAULT_SINK/SOURCE/MONITOR@ wildcards now work. This fixes the problem with volume keys when they are bound to scripts using pactl and the default sink/source wildcards. * the PIPEWIRE_LATENCY environment variable now works again * Fix some leaks of ports and port info. Also fix the leak of the context when the mainloop is stopped. * The sink/source format_info array is now filled up completely, this is actually not implemented yet in the real PulseAudio. - JACK layer improvements * jack now returns version 3.0.0 and has PipeWire in the version string so that apps can report this. PipeWire 0.3.11 This is a bugfix release that is API and ABI compatible with previous 0.3.x releases. - PipeWire improvements * Properly cleanup the mixer structures when a port is removed, this should fix client crashes related to port config changes and other random crashes. * Optimize the preferred formats in the audio converter. Higher quality formats with higher performance are chosen first. * Make sure the time reported by pw_stream is always increasing, even when the driver and clock changes. * There is now also a system service and socket that can be used to enable PipeWire systemwide. This is however not recommended and disabled by default. * Fix channelmixer 5.1 to stereo mix matrix. It was not reading the conversion matrix correctly and cause channels to be dropped. The channelmixer will now also normalize the volume, like what pulseaudio does. * The channelmixer will now just copy channels when no layout has been given. It has also optimized paths for this. This makes it possible for apps to request > 8 channels from the alsa plugin (ardour). * Port, Node and Link will now also emit an error on the resources in addition to updating the error in the info. This would make it easier to track negotiation errors in the session manager later. * many small fixes and cleanups. * Fix compatibility: + DOSBox: fix crash because of double free in pw_stream - Session manager improvements * The session manager will now try to configure the client to the channel configuration of the sink/source. It will only do this for downmixing, never for upmixing and also never when the client has the dont-remix property set. It will also renegotiate the channel layout when moving a stream to a new sink/source. * Configuration state is now saved in XDG_CONFIG_HOME. Previously it was saved in $HOME/.pipewire-media-session/ You can migrate the state by moving the files to $XDG_CONFIG_HOME/pipewire-media-session (or $HOME/.config/pipewire-media-session as a fallback when XDG_CONFIG_HOME is not set). - Device support * Bluetooth sources and sinks should work better now. * There is now also a new bluetooth backend using hsphfpd. * fix the ALSA UCM Off profile for alsa pcm devices * improve ALSA port and profile switching. The ACP device will now switch to the best port and profile when availability changes. - PulseAudio layer improvements * Implement some more callbacks. The pulse layer will now also notify applications of stream moved, started and latency changes. * Fix error code when an object was not found. We now return PA_ERR_NOENTITY instead of PA_ERR_INVALID. * Add some support for loading new null sinks. Applications such as pulseeffects use this. Note that pulseeffects does not yet work reliably but can start now. * Improve handling of profile and port updates, it should work much more reliable now. Apps should now also again receive volume updates from sinks/sources. * Fix compatibility: + openal-soft 1.20 + pavucontrol (checks PA_ERR_NOENTITY) - JACK layer improvements * improve default source and sink handling. It was not updated correctly in all cases. * add samplerate and period to the pw-jack wrapper to easily configure the desired samplerate and period for the app. - ALSA plugin improvements * Add a mixer entry in the alsa config file. * Implement support for planar types, rework the processing function to make it more robust. * refuse to load the alsa plugin when linked against 0.2. This catches some old apps linked against 0.2 that want to use the alsa plugin. * Fix compatibility: + linphone (ALSA SIGFPE when _status() is called before _prepare()). PipeWire 0.3.10 This is a bugfix release that is API and ABI compatible with previous 0.3.x releases. - Many improvements to the pulse layer. * GStreamer pulsesink element now works. * Fixes some segfaults. * Enable rtkit for client threads. * fixes capture of monitor stream by name * implement some more extensions, this makes paman work and removes some warnings. - Many improvements to the GStreamer elements * negotiation rework, avoid calling GStreamer methods from the PipeWire callbacks because they might block and cause deadlocks. * Add support for non-string property values. * improve stability after buffer and format renegotiation. * Rework the device provider. * pipewiresink can now provide a stream that can be consumed by apps like cheese. - Many improvements to the JACK layer: * Rework the buffer_size callbacks. Make sure we call the callback from a 'safe' thread and that we don't call the process callback while the application is handling the callback. This improves stability in apps like Carla when PipeWire dynamically changes the buffer size. * Improve compatibility with apps that call get_buffer_frames() with a 0 size (calfjackrack) * JACK can now create nodes that can be set as a sink/source in PulseAudio/ALSA apps (you can make an effects rack and set that as default sink for apps). - Added a group id property for nodes. This makes it possible to schedule nodes with the same driver even when they are otherwise not linked together. To make this work well a new flag needed to be added to nodes to signal when they are ready for processing. Together with the GStreamer fixes, this makes things like: gst-launch-1.0 -v pipewiresrc path=51 stream-properties="props,node.group=1" ! audio/x-raw ! pipewiresink stream-properties="props,node.group=1" work as expected with PipeWire managing the resampling to keep the clocks of the devices in sync. This can later also be used to force devices to be grouped together to create a JACK-like scheduling group. - Streams and filter now use PIPEWIRE_NODE and PIPEWIRE_LATENCY env variables as fallback. - ACP add per device port list. This makes UCM devices expose the right ports. - Fix some segfaults in ACP and UCM. - make pw-cat use the metadata to find default devices. - The media session can now save and load audio device Profiles and Routes (volumes), stream volumes and the default sink and sources. PipeWire 0.3.9 This is a bugfix release that is API and ABI compatible with previous 0.3.x releases. - Fix bad audio in chrome - Remove some errors that are not real errors. - Fix 100% cpu when disconnecting devices. - Improve pulseaudio introspection of formats - Fix JACK metadata handling, carla can now monitor the port it creates and insert midi. - Add a new permission bit (M) that is needed to be able to configure metadata on an object. Improve security of metadata some more, only allow metadata on objects that are visible to the client setting the metadata. - Add support for videocrop in the GStreamer elements. - Improve handling of the runtime directory for the server sockets. Add some reasonable fallback when XDG_RUNTIME_DIR is not set, as suggested in the spec. - Improve ALSA device names from ACP. - Fix various crasher bugs. One in the pulse layer, one in the session manager. - Make alsa plugin respect the PIPEWIRE_REMOTE env variable. - Various compile fixes. PipeWire 0.3.8 This is a bugfix release that is API and ABI compatible with previous 0.3.x releases. - Fix an embarrassing crasher in the JACK layer when metadata keys were removed. - Make it possible to add properties to jack clients with a PIPEWIRE_PROPS env variable. This can be used to make JACK nodes look like a device (like an effects rack). - Improvements in the session manager in how it links ports. Now it will try to link matching channels first and be more intelligent otherwise. The session manager will also configure the stream to the device port configuration when needed. - Add ofono backend for Bluetooth HeadSet support. - Improve default source and sink handling. They are now stored with their id, instead of name, in the metadata. This makes it work better with JACK because of JACK's limited name length. - Improve environment variables to make it possible to create and connect to servers other than "pipewire-0". Implement this in pulseaudio, JACK and alsa layers. - Add an alsa mixer plugin so that alsamixer works with PipeWire. It will configure the default source/sink volumes. - Fix capture devices. There was something wrong with how the resampler was used that caused corruption in the signal when the resampler was active. - We now ship alsa card paths, profile-sets configuration files and udev rules so that we don't have to rely on the pulseaudio ones. - Many build and stability fixes. PipeWire 0.3.7 This is a bugfix release that is API and ABI compatible with previous 0.3.x releases. - Improved PulseAudio compatibility. The alsa card profile code was reused from PulseAudio. Devices now support all profiles, ports, jack detection, UCM and hardware mixers that PulseAudio implements. There should not be (almost) any difference between PipeWire and PulseAudio in how it presents and manages devices. Other missing API pieces such as the default sink/source and move_stream are implemented now. At this point it should be possible to replace PulseAudio with the compatibility layer for those who want to try. - Many fixes and improvements to the GStreamer elements. pipewiresrc now has the ability to periodically resend the last frame. This makes it possible for use-cases like screensharing to only update the screen on changes while still keeping the client side encoder busy. PipeWire elements can now also share a connection between them. - Improvements to the bluetooth nodes. Dynamically adding and removing devices should work much smoother now. Many fixes and improvements to a2dp and sco nodes. - Reduced memory usage by using less pre-allocated memory where possible. JACK clients are especially using less memory. - Support for passive links is added again. These are links that don't cause the associated driver to become active. This makes it possible to have blocks of effects+sinks go to suspend as a group when not in use. - Both consumers and producers can now ask to renegotiate the format. This required some cleanups and improvements to how links and node states were handled. More work is needed to implement more use cases. - Important fixes to how memory is shared with clients. Memory was not correctly freed in all cases, which would result in reuse of the wrong memory. - Support for planar formats for audio and video was added. - Improved error handling in the session manager. - Metadata is now used to manage default audio source and sink devices. The session manager will try to link streams to the default device. Changing the default device will move streams to the new device. PulseAudio and JACK layers respect the default source/sinks. - Metadata is used to tag the desired output device for a stream and the session manager will move streams when the metadata changes. The PulseAudio layer uses this to implement the move_stream feature. - Many fixes to the security modules. The session manager now has a flatpak module that grants permissions to flatpak apps. The PulseAudio layer now respects the permissions of objects. Security related properties are made read-only now. Different access modules can now coexist. - The portal module has been split up in 2 parts: 1) a part living in the daemon that monitors the portal dbus owner and tags all clients from this PID. This part has to run in the daemon in order to securely tag the clients. 2) a part in the session manager that uses the permission store to manage the permissions of portal managed clients. PipeWire 0.3.6 This is a bugfix release that is API and ABI compatible with previous 0.3.x releases. - Extensive memory leak fixing and stress testing was done. A big leak in screen sharing with DMA-BUF was fixed. - Compile fixes - Stability improvements in jack and pulseaudio layers. - Added the old portal module to make the Camera portal work again. This will be moved to the session manager in future versions. - Improvements to the GStreamer source and sink shutdown. - Fix compatibility with v2 clients again when negotiating buffers. PipeWire 0.3.5 This is a bugfix release that is API and ABI compatible with previous 0.3.x releases. - Compiler fixes - Add pw-midiplay and pw-midirecord aliases - Add pw-mididump tool - Add pw-metadata tool to inspect, add and remove metadata for objects. - Docs updates, man pages - install alsa config files - Fix linked sink/source in pulseaudio - ratelimit graph processing warnings - improve buffer handling in GStreamer elements - Fix power usage by removing the queue for the alsa sequencer system announce messages. - Fix metadata clear() method dispatch. - Improve parameter enumeration, make it possible to detect missing parameters vs no-compatible parameters so that we can use defaults in the first case and error in the second case. - Fix cleanup of proxy objects. Stability improvements on plug/unplug in session manager. - Make it possible to set log level from config file - improve debug of param negotiation errors. Log the parameters to stderr/journal. - Make it possible to configure global logger implementation. - Fix NEON detection - JACK and PulseAudio compatibility improvements PipeWire 0.3.4 This is a bugfix release that is API and ABI compatible with previous 0.3.x releases. - A quick update with some important stability fixes. PipeWire 0.3.3 This is a bugfix release that is API and ABI compatible with previous 0.3.x releases. - NEON optimizations for audio conversion (32 and 64 bits) - rework of session manager implementation - Add option to disable modules in the session manager - Release midi hardware devices when suspended - various build fixes - Clean up options of various utils - Stability improvements - Mayor improvements in pulseaudio emulation. Improved timings and compatibility. - Implementation of drain and flush in pulse and alsa emulation. - Implement poll on file descriptors. - Improvement of metadata for jack emulation. - Fix memory and thread problems in jack emulation. - Simplification of state changes. Should make more use cases work in the jack emulation. - Improvements in the gstreamer elements. Removal of extra internal queue. pipewiresink can now be used to play audio. - Add pw-jack and pw-pulse scripts to run pulseaudio and jack applications with the right library path. PipeWire 0.3.2 This is a bugfix release that is API and ABI compatible with previous 0.3.x releases. - build fixes - Added support for data type negotiation. This makes it possible for a client to say that it can handle DMABuf and MemFd and then let the server select a compatible format. - Handle errors when enumerating parameters better. - Add support for rate, format, channels and period_bytes to the alsa config file to restrict what alsa apps can negotiate. - Fix JACK midi output. - Optimizations in common audio format conversions using AVX2. Small optimizations to plugins. - Change the vulkan compute example to an MIT licensed shader. - Remove some hardcoded defaults in the audio and video processing and use the values from the processing context. This also fixes the vulkan example. - Correct the documentation and defaults in the daemon config file. - Fix alsa and v4l2 buffer recycle. A paused client could cause the server to leak all buffers. - Remove some warnings that should be ignored. - Fix a crash in the bluez5 plugins. - Try to select higher quality formats first when negotiating a format with an audio device. - Fix an infinite loop in udev detection in some cases. - Add non-interactive mode to pw-cli. You can now just do "pw-cli ls Port" to get a listing of all ports. pw-cli will now also connect to the default server by default and has options to select a different server. - Allow the server to go up to the maximum quantum (8192 samples or ~=180ms) if a client explicitly wants this. PipeWire 0.3.1 This is a bugfix release that is API and ABI compatible with previous 0.3.x releases. - Don't load the rtkit module by default. It can cause a sigkill, which is not desirable for mutter, for example. Only enable this for the jack library for now. - Don't use pthread cancel by default because it uses a signal that might crash some apps. Only use it for the jack library because jack clients really expect this. - Build fixes for -Werror=suggest-attribute=format - improve error messages, don't report harmless errors and warnings. Try to send error messages to the proxy that started the operation or is the owner of the object. - pw-cat: midi improvement, add midi recording and dump in verbose mode - fix properties when loading spa-nodes from the config - Fix and update some examples - jack: check arguments and don't crash when invalid - Fix buffer memory upload. - jack: fix compatibility with zrythm. Fix timemaster install, improve sample_rate callback. Fix reposition handling. - fix crash in port after buffer negotiation error. - add support for control ports in pw_filter - fix cleanup of the metadata module - improve param enumeration. - Clear stream buffers when the format is cleared. - Add create-object command in the config file to create object from a factory. - Fix crash after the driver was not removed from unassigned nodes. Also properly pause inactive nodes. - Use "true" and "false" in properties when we are talking about a boolean. - pulseaudio: improve compatibility PipeWire 0.3.0 The 0.3 release is a major milestone in the development of PipeWire. It features a complete redesign of the scheduling mechanisms that make it possible to run a JACK compatibility layer with comparable performance to JACK2. The API has been reworked and is declared stable now. All development files and runtime paths are versioned so that future incompatible changes can be done without breaking existing applications. PipeWire 0.3 also includes a (now mandatory) session manager that populates and controls the PipeWire graph. This example session manager is very simple and not configurable. It is expected that future version will either switch to a more flexible session manager (like WirePlumber) or improve the configuration options of the example session manager. PipeWire 0.3 includes both PulseAudio, JACK and ALSA compatibility libraries that are known to support a wide range of applications. The ALSA library is pretty complete at this point. The JACK and mostly the PulseAudio compatibility libraries need more work. See the Wiki pages for the current compatibility problems. We do not yet encourage people to switch away from their existing audio solutions (PulseAudio or JACK) but we would love to hear from people who try it anyways. Future versions will mostly focus on improving compatibility further to make PipeWire a drop-in replacement. PipeWire comes with some GStreamer plugins to consume and produce data for PipeWire. The consumer (pipewiresrc) is working well in most cases. The sink (pipewiresink) is known to be somewhat problematic for now. PipeWire 0.2.97 Eighth pre-release for upcoming 0.3: - Build fixes - pw-cat improvement: Fix remote name, add midi support - add device subscribe params for completeness - jack and pulseaudio compatibility fixes - Fix a bug in resampler, add quality option, tweaked quality settings, tested now against https://src.infinitewave.ca/ testsignals and submitted results for publication. - Fix awkwardness in buffer negotiations, the default number of buffers was 4 and jack could only handle 2, causing corruption. Also implement negotiation of Step ranges. - Fix device reservation to work together with pulseaudio, previously we would block pulseaudio. PipeWire 0.2.96 Seventh pre-release for upcoming 0.3: - jack: improve compatibility - Fix unit test - Fix license of jack and alsa libs - Make start/stop more threadsafe - Fix rt-kit again, add params to configure things, increase default soft/hard limits to avoid being killed. - version 0 compatibility improvements, tested with firefox, cheese, GStreamer and chrome using compat layers. - Fix timing for gstreamer source - Require libspa in pkg-config file - Limit buffers to 16 to support old clients PipeWire 0.2.95 Sixth pre-release for upcoming 0.3: - Fix tests for big endian some more - Improve v2 compatibility mode: improve type negotiation and update_permissions - Workaround for firefox screen sharing PipeWire 0.2.94 Fifth pre-release for upcoming 0.3: - Fix man page names - Fix jack set_sync_timeout - Improve JACK compatibility with apps that cache buffer pointers. - Improve mlock failure warning message, add property to configure if mlock should be used. - Improve OBJECT_PATH in alsa objects - Install in versioned directory - Add pw-profiler tool - Improve pulseaudio compatibility wrt pa_operations - Thread safety fixes in remote nodes when activating/deactivating - Improve JACK names on duplicates - Add option to ignore failure when loading modules PipeWire 0.2.93 Fourth pre-release for upcoming 0.3: - Fix unit tests on 32 bits - Append -pw version to pulse and jack libs. This way we can install it next to the real libraries and use a symlink to enable it. - Improve jack support by killing threads with pthread_cancel. This then also remove the eventfd from the data-loop, making it maybe a little faster. - Fix jack_client_close() compatibility - Fix some segfaults in the session manager - Improve debug of protocol messages - Add examples options - Don't fail when alsa is not found - Fix some compiler warnings with a new spa_aprintf() helper. - Add pw-cat, the simple audio playback/record tool - Rename pipewire tools to pw- prefix - Add improve pw-cli object dump feature PipeWire 0.2.92 Third pre-release for upcoming 0.3: - Improve old version check some more - Fix unit tests on little/big endian - Fix compilation when CPU has no optimisations - Install jack and pulse libraries - Handle -EACCESS in flatpack access module PipeWire 0.2.91 It is mostly a bugfix release to make the new version install and run correctly in distros. - Install session manager, fix path to find the session manager - Fix alsa buffer reuse - Small fixes for crasher bugs - Implement pw_core_set_paused() to suspend/resume even processing. This can be used when using multiple connections to a daemon and one needs to pause one connection until the other one completes an action. Used by session managers. - Improve old version check PipeWire 0.2.90 This is the first pre-release of the 0.3 version. It consists of a major rewrite and is not API or ABI compatible with the 0.2 branch. PipeWire 0.2.7 This is mostly a bugfix release and is API/ABI compatible with previous 0.2 versions. Work is ongoing in the work branch that features a completely new scheduling method that will enable audio support. Some of these API changes are backported in this branch. - Add support for alsa-lib 1.1.9 which changed the include path - Improve error checking and reporting in the protocol - deviceprovider: fix probing without starting - add sentinel to some functions - compiler fixes for musl - Revert object tree permission checks that broke things, this is probably not a good idea (and the tree of objects is going to be removed later) PipeWire 0.2.6 - Improve error checking for threads - Fix some memory and fd leaks - Fix compilation with C++ compilers and clang - DISABLE_RTKIT should now not try to use dbus at all - Camera Portal fixes: - add Camera media.role - Rename module-flatpak to module-portal - Use the portal permissions store for camera checks - Actually use the passed fd in pipewiresrc - Make properties with "pipewire." prefix read-only - Add security label to client object - Enforce link permissions - Permissions of objects are now combined with parent permissions - Remove libv4l2 dependency, it is not used - Improve format negotiation in autolink #146 - Try to avoid list corruption with event emission #143 - Fix destroy of client-node memory corruption - Various small improvements PipeWire 0.2.5 - build fixes for systemd - Add cursor and bitmap metadata.
