PipeWire 0.3.18
This is a bugfix release that is API and ABI compatible
with previous 0.3.x releases.
- Highlights
- More work in the PulseAudio server. It should be compatible
with more applications.
- Bluetooth now support extra codecs such as AptX/HD and LDAC.
- Support for virtual sources and sink was improved a lot.
- Added a new pw-dump tool to dump the objects in JSON formats
and for filtering them with tools like jq.
- Many more stability fixes and improvements.
- PipeWire improvements
- Silence some harmless warnings
- pw-cli can now be used to set parameters.
- Streams now perform the correct channel mapping when linked
to non-standard multichannel devices. Previously channels
would get swapped.
- port, node and device params are now cached in the server.
This avoids opening and closing devices whenever some client
enumerates formats, which improves performance a lot,
especially in cases where opening a device is slow.
- Add a command to keep a device open during negotiation. This
is used to enumerate and set a format while opening the
device just once, improving performance.
- The null-sink scheduling was fixed.
- A memory corruption bug was fixed in format conversion, this
could cause crashes, silent channels or other undefined
behaviour.
- There is now a simple JSON parser.
- Session-manager
- Settings files are now stored in JSON. With the json parser
this is easier to parse and extend
- Device support
- Bluetooth now supports additional codecs: LDAC, AptX and
AptX HD. LDAC is known to not work very well yet.
- ALSA devices will now default to the max supported channels
if nothing else is specified. This makes it possible to use
8+ channel cards with the alsa-pcm module, which is not
supported with the default alsa-acp module.
- Enable mSBC support in oFono.
- Add an option to disable hardware mixers
- ALSA now improves support for batch devices.
- The udev rules had references to Pulseaudio removed in order
to not create conflicts.
- Fix a potential crash in bluetooth devices when
disconnecting.
- UCM cards now use HW volume when possible.
- PulseAudio server
- The id can now be used as the name to locate cards and
devices
- Report streams with planar formats as well
- Better error reporting when stream create fails
- module-null-sink can now handle channels, rate and
channel_map properties
- Add support for 3 types of virtual devices: source,
sink and duplex.
- set-port was fixed
- Some buffer parameters were tweaked to improve
performance, compatibility and stuttering with lower
latency.
- NULL can be used as a name for the device sink/source
- Support lookup of monitor names
- Set properties more like pulseaudio so that some
clients (Teamspeak) don't crash anymore
