Keep track of the negotiated parameters and use those to construct
the Buffers param.
Use the FrameAllocator to allocate buffer memory. Keep a request for
each buffer and queue them.
In requestComplete, put the request metadata info into the buffer and
header and write the finished buffer id to a ringbuffer. Then wake up
the data thread to pop the finished buffer_id and push it in the
graph.
Remove some old files.
Keep track of the proxies and remove them when the global is removed.
Otherwise we might end up in a case where the have 2 proxies when
an add/remove/add sequence of messages was queued.
When an object is created, it is marked creating until all roundtrips
complete. If the object is removed in between, we don't remove it
because find_object does not return creating objects.
Make find_object also return the creating objects to fix this.
The current compile-time-check only tests for the getrandom() syscall
wrapper of libc. The presence of this wrapper however does not relate to
the presence of the actual syscall at runtime.
gstreamer alsasink can change sample while stream is already created.
In that case, gstreamer calls snd_pcm_ioplug_callback_t::stop,
snd_pcm_ioplug_callback_t::hw_params and snd_pcm_ioplug_callback_t::prepare
Add new flag to the snd_pcm_pipewire_t that is set every time
snd_pcm_pipewire_hw_params is called to prevent using stream with old
sample rate

pw->time.delay is delay in number of frames in pw->time.rate domain,
however snd_pcm_pipewire_delay function is suppose to return number of
frames in io->rate domain. Convert pw->time.delay to io->rate domain to
increase precision when the io->rate is not equal to the pw->time.rate
snd_pcm_pipewire_delay should return how many frames are queued in
pipewire, pw_stream_get_time returns numbers of the queued frames before
snd_pcm_pipewire_process is called, however this function inserts (or
removes) some frames from pipewire. Therefore newly inserted (removed)
frames should be added to pw->time.delay to increase precision.

Instead of doing pointer arithmetic through actual pointers, cast them
to the proper integer types.
This is functionally equivalent to the previous code but is clearer for
the compiler.
Fixes#1018
Add a jack.show-monitor option (default true) that makes it possible
to hide the monitor ports.
Monitor ports are not enabled by default on JACK and maybe they also
should not for PipeWire. Or maybe we need some tweaks for some apps.
See #1760
pw-v4l2 uses the gnu ld's ${LIB} features, see meson.build.
Make it possible to work around this by specifying an explicit path,
just like for pw-jac.
Fixes#1751
You are supposed to allocate with _insert_new()/_remove() or use
someone elses allocated number with _insert_at(), never mix the
two or it will give an error.
Sami Farin pointed out on #833 that on Linux kernels older than 5.6,
/dev/random blocks when entropy estimates are too low, whereas
/dev/urandom does not.

Let video-src unconditionally call _trigger_process() when it is
ready. This will either start the graph when it is the driver or emit
a RequestProcess event to the driver.
Let video-play-pull intercept the RequestProcess command and use it
to do a trigger_process(). Otherwise use a timer to pull in the next
frame.
The event is emitted by a node that is not a driver but wants the graph
to be scheduled. The command is sent to the driver and suggest that the
graph be scheduled.
This commit uses the video-src-alloc and video-play-reneg templates to create
examples for manual fixation at the format negotiation phase. These
clients simulate modifier negotiation done by clients handling DmaBufs.
Note: Neither client is capable of proper DmaBuf handling!
video-play-fixate can be used to test if a producer is capable to
fallback to shm buffer transport, while video-src-fixate can only be
used with the former example!
Send unfixed Format to nodes but don't proceed to the next state.
When EnumFormat is emited, change the link state back to INIT to restart
the negotiation.

Commit 42d8b2b1 "Remove legacy FreeBSD compatibility code" removed
compatibility with old versions of FreeBSD, but also removed
compatibility with old versions of Linux and glibc, which was requested
in #833.
This partially reverts commit 42d8b2b167.
Resolves: #833

Dequeue a new buffer only once and reuse this queued buffer when
jack_port_get_buffer() is called multiple times in process().
Recycle an old buffer in the next cycle.
After calling process, mark all input buffers as consumed, process the
empty buffers and move the output buffers to the mix ports.
Fixes#1748
In Meson, string.contains() is a substring check but array.contains() is
a full string check. Let's use 'foo in bar' style instead to avoid
confusion.
Supported since meson 0.49.0
When we get to this code, we already updated the environment variables
so we need to use the usual error path to restore them.
And where chdir does fail, print an error to the log. 256 chars should
be enough here, if your tmpdir exceeds that you just have the error
message cut off.
count the number of changes and then when there are any, flip the
SERIAL bit in the param info so that the server can detect a
change. Without this, 2 updated params would not flip the bit and the
param changes would not be noticed.
