PipeWire 0.3.67 (2023-03-09)

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

Highlights

• The loopback module and other couples streams will now not randomly fail in some cases. (#3028)
• The RTP module now has support for sending and receiving MIDI as well.
• The compress offload sink has seen many improvements. It now uses ioctls directly to bypass limitations of tinycompress (to be able to detect the available codecs, for example).
• Pulse server compatibility was improved for some apps by improving the format parsing and FIX_ stream flag handling.
• The min quantum in the pulse server was changed from 256/48000 to 128/48000 to fix some issues with games that expect 5ms or less of latency.
• The Bluetooth plugin has seen many improvements in packet scheduling to attempt to reduce stuttering on some devices.
• The ALSA plugin now handles some impossible cases better. This fixes recording in QEMU again. (#2971)

## PipeWire

• SPDX tags were added to the code for copyright information.
• The random number functions were made more usable.
• The port property code was moved from the adapter to the port implementation itself to make it more useful and unified for the cases where no adapter is used (midi and video).
• Fix a potential overflow in mixer areas.
• Improve runnable state calculations of nodes. This is part of ongoing work to avoid running nodes that should not need to run.
• The stream will now always call the process function when using trigger, even if there are no buffers. This avoids stalls of the processing graph in some cases. (#3028)
• Links are now marked as passive by PipeWire itself so that the right thing happens in all cases.
• Implement the in/out/true values for the node.passive property. Place a passive state on ports to make passive links on a port by port basis.

## Tools

• pw-cat has seen improvements in the encoded file playback case.

## Modules

• The rtp module has support for MIDI now.
• DSCP is now configurable in the RTP module.
• The loopback module doesn't randomly fail to work anymore. #3028)

## SPA

• The null-audio sink can now be given a format and it will return this instead of the default float ones. This makes it possible to make a null-sink that has a given format.
• The compress offload sink has seen many improvements. It now no longer uses tinycompress to be able to detect the available codecs.
• The ALSA plugin now handles some impossible cases better. (#2971)
• Fix compilation on older compilers. (#3050)

## Pulse-server

• The FIX_ flags are now implemented more correctly by fixating the stream to the format of the sink/source they ask to be connected to. There is now also an option to override the fixation based on rules.
• Format parsing was improved and should now support all format strings supported by pulseaudio including upper and lower case variants and shortcuts.
• Channelmap parsing was improved and should now reject invalid channelmaps as well as support the shortcuts supported by pulseaudio.
• Escape codes in module arguments now work as it does in pulseaudio. (#3071)
• The min quantum was changed from 256/48000 to 128/48000 to fix some issues with games that expect 5ms or less of latency.

## JACK

• jack.passive-links can now be used to have a JACK client make passive links and the node.passive property is no longer used for this because it has a different function.
• The qsynth rule was updated to the new node.passive features. It is now only passive on the output side.

## Bluetooth

• BAP delay and transport latency are handled now.
• A2DP and SCO can now use bigger buffers to improve quality when the reception is jittery.
• The AT+BCC command is now implemented.
• Packet encoding now happens ahead of time when possible to avoid delays before sending it.
• Source should now always produce complete (padded) buffers to avoid sync problems.
• Don't set unnecessary socket options.

## GStreamer

• The pipewiresrc now has an autoconnect argument.
• The metadata plane count is now handled correctly in more cases.
• Stream errors are now handled correctly to stop the GStreamer elements.
