- Update to version 0.3.40:
* Highlights:
- Producers and consumers can now incrementally negotiate a
format by narrowing down the options. This can be used to
select an optimal combination of format and modifiers.
- Driver nodes such as the consumer of a headless compositor
can now throttle the speed based on a new trigger_done event.
- Headless compositors can now signal a damage event to
consumers to start the processing of the graph.
- Compatibility improvements in JACK.
- Draining and resuming is now working correctly in pulse and
alsa.
- Many bugfixes and improvements.
* PipeWire:
- Many BSD fixes.
- clang compilation fixes.
- Fix map implementation on big-endian machines.
- Improve tracking of param changes in pw-stream.
- Add support for renegotiation. With this change, producer and
consumer can incrementally renegotiate a format until it is
fixed. This will be used to do complex negotiation of DRM
modifiers.
- Add a trigger-done event in the stream. This can be used to
know when processing of the complete graph has finished after
issuing a trigger_process() and it can be used to throttle
processing.
- Add a RequestProcess node event and command. This can be used
by non-driver nodes to suggest to a driver to start
processing. One case is where a compositor can emit this
event as a result of a screen update to let the headless
compositor start an update.
- Fix zeroconf sample format.
- pw-mon outputs to stderr now and has colors.
* SPA:
- Fix compilation on ppc and armv7.
- Fix port type check for ALSA seq midi ports so that they are
not falsely listed as hardware.
- Fix crash when running SSE code on unsupported HW.
- The libcamera plugin was rewritten. It now supports hotplug,
format enumeration and an easier to read codebase.
- Fix compatibility some more for cards with 64 channels.
* pulse-server:
- Flush data in pause in combine-sink to avoid stray audio
fragments.
- Fix a race where not all objects were removed correctly.
- The latency calculations and setup was improved to more
closely match pulseaudio behaviour. PULSE_LATENCY_MSEC should
now resemble pulseaudio more closely.
- The drained reply is now sent only once and new data will be
accepted once the drain completes.
- Fix a potential crasher bug where the stream started
processing before the setup was completed.
- The server will now drop the client connections when the
pipewire connection is lost.
* JACK:
- Rework the jack_port_get_buffer() method to return the same
memory when called multiple times during the process()
callback. This makes things work on a new Hydrogen.
- Add an option to disable showing the monitor ports.
- JACK ports are now sorted per node/client and port_id. This
should more closely match JACK behaviour and avoid random
port order.
* v4l2:
- Fix v4l2 LD_PRELOAD script.
- Make sure we destroy the proxy when the global is destroyed.
* ALSA:
- _prepare should exit the draining state.
- Fix the precision of the _delay function by taking into
account the amount of queued samples are the correct
samplerate.
- Drop patches fixed upstream:
* 0001-cpu-fix-compilation-on-some-architectures.patch
* 0001-map-make-_insert_at-fail-on-a-removed-item.patch
* 0002-map-use-uintptr_t-for-the-next-pointer.patch
