Use a 0 mask to handle unknown layouts. When the source or destination
is an unknown layout, pair, distribute or average. When pairing, keep
track how we paired and use that to construct the matrix later.
This fixes [ UNK UNK ] -> [ FL FR ] mapping by pairing.
Many distributions provide outdated libcamera versions. This change should also help making changes to libcamera itself.
System libcamera is kept a default to avoid breaking existing build processes relying to packaged libcamera.
Handle MONO layout as a real layout, not just like FC. This means it
does not share the FC mixing weights.
Only distribute and combine MONO channels when the target is also
MONO, enable normalization in this case.
Otherwise downmix and upmix the mono channels like any other channel,
which will make it respect the upmix and other settings.
Change some tests with this new way of doing things.
Fixes#3010
Codec switching does not currently work properly for source/duplex.
With BAP it's also possible only when we're BAP client.
When we can't codec switch, emit the "codecless" BAP profile.
When we are rate matching, keep some more headroom to make sure we
have enough data for the adaptive resampler.
Fixes crackling when following the dummy node and probably also when
following another capture device.
Add support for using other clocks.
clock.id can be used to set one of the system clocks.
clock.device can be used to open a clock device such as a PTP clock
device.
Use a dll to track the progress of non-monotonic clocks.
We always probe the Pro Audio profile with the maximum number of
channels but this can lead to a more limited amount of sample rates.
Add an option to set the channels used when probing so that the other
samplerates become available.
Fixes#2990
BAP Clients do not have endpoints associated with them, and we only know
that codecs on currently configured transports are supported.
Handle this case in spa_bt_device_supports_media_codec
BlueZ fails registering object managers containing A2DP endpoints if
controller is in LE-only mode.
Make the A2DP and BAP object managers separate, so that failure to
register one does not prevent registering the other.
Also rename some functions to indicate which ones deal with the legacy
BlueZ API.
Strip initial \n from commands: some devices (Sennheiser HD 350BT) send
them.
Only reply OK to empty command with terminated command line;
non-terminated lines are invalid.
Add some debug in case the RFCOMM reply contains non-printable
characters.
The Bluetooth Low Energy MIDI code added a few legacy function declarations
that fail when building with -Werror=strict-prototypes. The fix is same as
before: add a void to the empty function argument list.

* Decouple FFmpeg integration in pw-cat from the ffmpeg option; if
one wants to use Compress-Offload but not the ffmpeg SPA plugin,
it is then possible to just pass -Dpw-cat-ffmpeg=enabled to meson.
Likewise, this also makes it possible to build the ffmpeg plugin
without extending pw-cat.
* tinycompress does not need to be detected in the root meson.build,
since it is only needed by the alsa plugin.
WirePlumber checks for the ENCODED audio format to determine if the
format is compressed/encoded. Without this info, it is not able
to automatically link compressed audio nodes.
