# PipeWire 0.3.60 (2022-11-10)
|
||||||
|
|
||||||
|
This is a bugfix release that is API and ABI compatible with previous
|
||||||
|
0.3.x releases.
|
||||||
|
|
||||||
|
## Highlights
|
||||||
|
- The filter-chain now handles errors better and has fixes for many
|
||||||
|
crasher bugs.
|
||||||
|
- A new RTP module was added with a sender and receiver. It uses SAP
|
||||||
|
to announce and consume RTP streams and is compatible with the
|
||||||
|
PulseAudio RTP modules.
|
||||||
|
- Many small bluetooth improvements and fixes.
|
||||||
|
- The alsa plugin will now only start playback when there is data. This
|
||||||
|
results in better sync and lower latency between capture and playback.
|
||||||
|
- The v4l2 and libcamera plugins have seen a lot of improvements. They
|
||||||
|
support control properties now. Also pw-v4l2 has seen many improvements
|
||||||
|
and mostly passes the v4l2-compliance test now.
|
||||||
|
- Many more bugfixes and improvements.
|
||||||
|
|
||||||
|
|
||||||
|
## PipeWire
|
||||||
|
- Code cleanups, compiler warning fixes.
|
||||||
|
- Add some extra checks to avoid scheduling an inactive node.
|
||||||
|
- Rework the sequence of events to start and stop nodes.
|
||||||
|
- Improve param enumeration.
|
||||||
|
- An option was added to give priority to the Buffer params of the
|
||||||
|
consumer. This makes it possible to use the default values of the
|
||||||
|
consumer (instead of the producer) when capturing from a source.
|
||||||
|
- The graph rate selection was improved to pick a rate closest to the
|
||||||
|
requested one (instead of picking the default).
|
||||||
|
|
||||||
|
## Modules
|
||||||
|
- Fix some crashes in filter-chain. (#2737)
|
||||||
|
- X11 Bell module will now be loaded by default when available.
|
||||||
|
- A new RTP module was added with a sender and receiver. It uses SAP
|
||||||
|
to announce and consume RTP streams and is compatible with the
|
||||||
|
PulseAudio RTP modules.
|
||||||
|
- Improve RAOP compatibility.
|
||||||
|
- The echo-cancel module now uses the resampler prefill option to align
|
||||||
|
input and output samples without buffering. Better latency control
|
||||||
|
when starting and stopping has been implemented.
|
||||||
|
- The pulse tunnel will now write aligned samples to pulseaudio even
|
||||||
|
when the ringbuffer wraps around. This fixes playback issues with
|
||||||
|
multichannel sinks.
|
||||||
|
- Add a delay option to module-loopback using a ringbuffer.
|
||||||
|
- Implement echo-cancel params.
|
||||||
|
- The filter-chain module has better error reporting.
|
||||||
|
- The LADSPA search path was extended with some more common paths.
|
||||||
|
- The echo-canceler input can now also be a monitor of a sink. This
|
||||||
|
improves compatibility with some proton games that expect a real
|
||||||
|
sink instead of a virtual one.
|
||||||
|
|
||||||
|
## Tools
|
||||||
|
- Better error reporting in pw-link.
|
||||||
|
- pw-top now also shows IEC958 passthrough formats and JPEG/H264 video
|
||||||
|
formats.
|
||||||
|
- pw-top refreshes the screen faster.
|
||||||
|
- pw-top now prints the state of the node and shows less info for
|
||||||
|
inactive nodes.
|
||||||
|
- pw-dump now uses the new seq field in the spa_param_info to discard
|
||||||
|
old param updates and avoid duplicate params in the output.
|
||||||
|
|
||||||
|
## Bluetooth
|
||||||
|
- Add ModemManager support in the native backend.
|
||||||
|
- Clean up GetManagedObjects handling.
|
||||||
|
- Handle QoS from the endpoints in the codec.
|
||||||
|
- Increase the socket buffer to have more control over the rate and QoS.
|
||||||
|
- Simplify the packet flushing code.
|
||||||
|
- Stop processing nodes before destroying them.
|
||||||
|
- Fix timers when a source switches drivers.
|
||||||
|
- Codecs can now share endpoints. This reduces the amount of endpoints and
|
||||||
|
avoids problems with devices that can't handle a large amount of
|
||||||
|
codec endpoints.
|
||||||
|
- Report batery status to UPower for HFP AG.
|
||||||
|
- Fix bitpool increase.
|
||||||
|
|
||||||
|
## SPA
|
||||||
|
- The audioresampler now avoids clicks and pops between activating and
|
||||||
|
deactivating the adaptive resampler when used by the stream API.
|
||||||
|
- Use default locale to parse float parameters.
|
||||||
|
- The upmix functions now have SSE optimizations.
|
||||||
|
- Avoid recalculating the complete channelmix setup when only the
|
||||||
|
volume changes.
|
||||||
|
- The alsa plugin will now only start playback when there is data. This
|
||||||
|
results in better sync and lower latency between capture and playback.
|
||||||
|
- The ALSA MIDI sequencer will now pull data from the graph even when it
|
||||||
|
did not output anything. Fixes some graph stalls with the sequencer in
|
||||||
|
some cases. (#2775)
|
||||||
|
- v4l2 and libcamera sources now recycle buffers when nothing is consuming
|
||||||
|
them. This avoids stalling the graph.
|
||||||
|
- libcamera now suggests a more appropriate frame size than the smallest
|
||||||
|
poster frame.
|
||||||
|
- Improve state changes in audioconvert. (#2764)
|
||||||
|
- A new seq field was added to spa_param_info to keep track of pending
|
||||||
|
param updates.
|
||||||
|
- Support speaker output only on RealTek ALC4080. (#2744)
|
||||||
|
- The v4l2 source now supports setting controls.
|
||||||
|
- The libcamera plugin now supports enumerating and setting controls.
|
||||||
|
- A new unit test for 6.1 channel mapping was added. (#2809) More debug
|
||||||
|
info was added to audioconvert for the channel matrix.
|
||||||
|
- Audioconvert will now also upmix a rear-center channel when needed.
|
||||||
|
|
||||||
|
## pulse-server
|
||||||
|
- Add support for the RTP send and recv modules with the new native
|
||||||
|
RTP module.
|
||||||
|
- Add option to set latency for pulse-tunnel streams and
|
||||||
|
module-zeroconf-discover.
|
||||||
|
- The socket will now be given the same permissions as what pulseaudio
|
||||||
|
did (0777).
|
||||||
|
- Implement module-loopback latency_msec correctly with the new delay
|
||||||
|
parameter.
|
||||||
|
- sysfs.path is now filled with the same data as pulseaudio.
|
||||||
|
- The manager now uses the new seq field in the spa_param_info.
|
||||||
|
- Fix a bug where in some cases the read pointer would get out of sync
|
||||||
|
and cause too large requests. (#2799)
|
||||||
|
|
||||||
|
## ALSA
|
||||||
|
- The alsa plugin now reuses the stream in prepare which results in
|
||||||
|
better performance.
|
||||||
|
- Some deadlocks have been fixed in the ALSA plugin.
|
||||||
|
- The ALSA plugin reports more accurate timing information in some cases.
|
||||||
|
|
||||||
|
## V4l2
|
||||||
|
- The v4l2 compatibility layer has received a lot of updates.
|
||||||
|
- Improved node names and format enumeration.
|
||||||
|
- Support for multiple /dev/videoX devices, each mapped to a unique
|
||||||
|
PipeWire node.
|
||||||
|
- Passes the v4l2-compliance test now with both the v4l2 and libcamera
|
||||||
|
backend in PipeWire.
|
||||||
|
- Improved mmap support for inline buffer memory. This makes it possible to
|
||||||
|
consume PipeWire streams.
|
||||||
|
- Negotiation works more reliably now.
|
||||||
|
|
||||||
|
## JACK
|
||||||
|
- Implement jack_acquire_real_time_scheduling() and
|
||||||
|
jack_drop_real_time_scheduling() by keeping the thread utils in a global
|
||||||
|
state.
|
||||||
|
- Fix jack_client_thread_id() to return NULL when the client is not active,
|
||||||
|
just like jack1 and jack2.
|
||||||
|
- An option was added to let the jack_set_buffer_size() function update the
|
||||||
|
global metadata. A quirk was added so that jack_bufsize uses this new feature
|
||||||
|
to make the buffer size settings persistent and global, just like jack.
|
||||||
|
- jack_port_register() and jack_port_unregister() can be called on an
|
||||||
|
active client so make this thread safe. (#2652)
