Make it possible to conditionally load modules, objects and exec by
adding match rules for context properties.
This makes it possible to only load a module when property is set,
which makes it possible to unset a property in a local config to disable
module loading. One example is the x11 modules, which can then be
disabled on a per user bases based on config overrides.
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.
The offset in GstVideoMeta point to location of merge-mapped buffer memories (see "gst_buffer_find_memory()") instead of raw memory location for each plane, make adjustment to comply this rule.
Also some cleanups.

Refuse to map a file if the specified `offset + size` would
be bigger than the size of the file. This prevents receiving
SIGBUS when the consumer tries to make an incorrect mapping.
See #2617#2914#3007
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.
Use the timestamps directly as the ringbuffer index. We can save some
conversions to bytes and there is a direct mapping to RTP timestamp,
clock position and ringbuffer index.
Simplify the source a little. Remove the buffering state, we always
start with read and write pointers separted by the target buffering.
Always write to index of the clock, not just for the first packet.
This ensure the timestamp on the packet always matches the time it was
processed in the graph.
Always use the timestamp of the graph clock for RTP packets. Add an
option to apply a random or fixed offset.
Add a ts-refclk option on the sender to specify a reference clock to
use for timestamping. This will activate the direct timestamp mode and
signal this in the SDP.
Parse ts-refclk and ts-offset from the SDP. Make it possible to match
them in rules. Add option to activate the direct-timestamp, where the
rate matching is disabled and the timestamps are used directly for
writing and reading from the ringbuffer using the graph clock.
This makes it possible to set a PTP clock on sink and source and avoid
rate matching by using a shared clock.
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
Use the control changes to load a new IR, then signal to data thread to
use the new IR. In the data thread, signal the main thread to free the old
IR after we swapped it out.
THis moves all allocations from the data thread into the main thread.
SOFA is a file format used for storing and accessing spatial audio data, namely head-related transfer functions. These can be used to create binaural spatial sound using head- or earphones.
This commit introduces libmysofa as an optional dependency for loading SOFA files and creates a spatializer plugin for the filter-chain
ci: install libmysofa-devel for full build

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.
For lower than default rates, limit the upsampling to 2 times the default
rate. This avoid 8000Hz to the upsampled to 192000 when a 44100 is
available (but not 48000).
For higher rates limit the upsampling to *3.
Try to upsample to something in the same rate family so that the amount
of resample filter is minimal.
If that doesn't work, try to downsample to something in the same rate
family above the 44100 threshold.
If that also doesn't work, downsample to the highest available samplerate.
