PipeWire 0.3.13

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

  • PipeWire improvements
    • Add pw-reserve tool to reserve or monitor a device on DBus.
    • Install spa-resample, a tool to resample a file.
    • Install spa-acp-tool, a tool to inspect the card profile.
    • Various fixes and improvements
    • Fix a bug in pw-stream where a capture stream could run out of buffers and become silent.
    • Rework the processing loops in the adapter and stream. There is now less latency in PulseAudio and ALSA layers.
  • Session manager improvements
    • Improve the device reservation code. We now try to acquire the device using the dbus device reservation API before we probe the device. This avoids conflicts with a running PulseAudio where devices would disappear (because they were locked by the other process).
    • Don't fail on invalid input from the config files.
    • Audio devices now have the same name as what PulseAudio would assign.
  • Device support
    • v4l2: try to use the format before enumerating the size and framerate. Some drivers don't check the format and might now work better.
    • v4l2: Fall back to MMAP when EXPBUF fails. Fix MMAP access, just export the fd and the mapoffset. This should make more devices work.
    • Fix crash in ALSA Card Profile (ACP) code.
    • ACP: fix selection of default profile. Prefer any possibly available profile over 'Off'. This makes some card at least start with something.
    • Fix soft volume. After setting the volume to 0, it would stay at 0 until pushed over the max volume. This should fix various volume related issues.
  • PulseAudio layer improvements
    • Rework the buffering and latency measurements and tweak the buffer attributes. This should make browsers and media players work better. This should also improve speechd performance.
  • JACK layer improvements
    • Fix compilation against newer JACK.
