Use this to override the default $PIPEWIRE_CONFIG_DIR/media-session.d
directory. This allows us to have separate configuration directories for
pipewire and media-session.
AUX channels can link to any other channel but when AUX channels are
linked, they must match exactly.
Fixes some issues with split devices with aux channels.
check if a node has AUX channels and mark it as unpositioned in that
case.
If the peer node we need to link to has unpositioned channels, don't try
to configure the node for the unpositioned layout but instead configure
it to its default format and link the ports one by one, as many as there
are.
This is mostly for Pro-audio devices. It does not make sense to
try to remix a stereo stream to 18 channels. Most likely the pro-audio
card does not have 18 speakers connected and we would not known how to
remix anyway because the channels don't have a position. So, just take
the 2 channels and link them to the 2 first AUX inputs, which is usually
more correct and mimics what other players do when outputting to JACK.
If a specific remapping needs to be done for the pro-audio card, it
needs to be configured with a virtual device.
Media-session itself uses ms.core, there are only two files that could
have a sub-topic but right now they don't use it (match-rules and
metadata).
The modules use the ms.mod.* namespace, so it's trivial to filter on
those.
Previous commit 69e935e unconditionally called pw_log_set_level() after
the option parsing. If pw_init() changed the logging level based on
PIPEWIRE_DEBUG, we'd now overwrite that change.
Call pw_log_set_level() only if -v is actually given on the commandline.
This means a commandline option will override PIPEWIRE_DEBUG if set but
that is intended.
Fixes 69e935e8a4
