pipewire-0.3.80

[Xi Ruoyao]

New patch version.

[Xi Ruoyao]

This is a bugfix release that is API and ABI compatible with previous 0.3.x releases.

## Highlights

• A new Tag param was added that allows arbitrary metadata to be transported out-of-band in the graph.
• Vulkan DMA buf support was merged.
• The echo-canceller was ported to webrtc-audio-processing-1.
• Fix a regression in locating monitor sources by id in pulse-server.
• Mixer io areas updates are now synchronized correctly with the data thread to avoid potential crashes.
• Many more bugfixes and improvements.

## PipeWire

• Handle driver nodes that refuse to change the quantum or rate.
• A new Tag param was added that allows arbitrary metadata to be transported out-of-band in the graph.

## Modules

• The pipe-tunnel source has been reworked to use a ringbuffer and rate adaption to keep the latency constant. It can now also function as a driver to reduce resampling. (#3478)

## Tools

• pw-cat will now place media properties in Tag params.
• pw-mon can now filter props and params.

## SPA

• ALSA refuses to change quantum and rate when in IRQ mode.
• ALSA will now be smarter in selecting the period size for batch devices and will make it depend on the samplerate. (#3444)
• Vulkan DMA buf support was merged.
• ALSA latency will now be reported in the time domain of the graph.
• Add udev based autodetection for compress-offload devices.
• The echo-canceller was ported to webrtc-audio-processing-1.
• The v4l2 inotify code was rewritten to avoid a use-after-free and by using a separate watch (but same fd) for each device. (#3439)
• The tag and latency handling was improved in audioadpter.
• Don't use -Ofast on alpha because it can crash on denormalized values. (#3489)
• The mixers now synchronize spa_io_buffers updates with the data thread to avoid crashes.
• Handle NULL param updates. (#3504)

## Pulse-server

• Fix a regression in locating monitor sources by id. (#3476)
• Add support for use_system_clock_for_timing in module-pipe-sink.
• Add support for checking module arguments.
• Avoid some useless change events.

## Bluetooth

• Ports are now marked as physical, which makes the bluetooth devices show up as hardware devices in Ardour and other JACK apps. (#3418)
• Some fixes for LE audio support (#3479)

## JACK

• Also emit unregister notify even when supressed when creating the client.
• The notify callbacks now match JACK2 behaviour more.
• The mixer io areas are updated and handled safely now to avoid crashes. (#3506)
