Reduce fallback delay values used when BT device doesn't provide the
information itself.
It may be better to have audio late than early, so use values that are
probably close to or below the delays of majority of headsets.
Don't include the quantum in latency: the latency relative to graph
cycle start doesn't depend on the quantum. Instead, the audio packet
size determines it.
Enable the /Internal media class hack also for SCO.
Session manager can use this to adjust SCO sink/source media.class when
it is going to emit front-end nodes hiding the hardware ones.
The rfcomm list may contain various AG & HF ones, so the profile must be
checked everywhere they are looked up.
Fix the rfcomm lookups everywhere to do it.
Fixes Pipewire<->Pipewire HFP connections, and sending HFP HF commands
to HSP or AG.
HFP 1.9 adds LC3 as a possible codec in addition to CVSD & mSBC.
E.g. Pixel Buds Pro latest firmware supports it.
Add the RFCOMM side and codec selection for it.
Move some of the tracking code for the DLL to where it is used.
Add resync.ms (default 10) option at which we give up rate adjusting
and instead do a hard resync. This results in a jump in the position
of the graph clock.
Devices may advertise other values, but not certain they will work well
in duplex configuration.
E.g. my Samsung Galaxy Buds2 Pro emits buzzing sound with 48kHz duplex
input.
Don't believe QoS values recommended by the device, which may be
suboptimal. Instead, pick the values from the BAP v1.0.1 Table 5.2.

The PAC profile UUIDs do not appear in the UUID list, but are still
useful to know before SelectProperties.
Set them ahead of time based on the visible remote endpoints.
The "default" codec is the one with fill_caps != NULL, and should be
picked if we don't know which one we are using.
Fixes showing AAC-ELD as supported when it's not, which happened because
it's ordered before the default AAC in the codec list unlike the other
"shared endpoint" codecs.
We need a database of pixel format properties to remove hardcoded magic
numbers. This commit creates a simple function to query the bytes per
pixel for common RGBA formats.
This should be promoted to or superseeded by a common spa namespaced
version.
This splots the format enumeration into a helper for dsp and raw pod
creation and a common function for the compute filters.
Counting formats with modifiers will be usefull to announce dsp and
raw formats from the same node.
No functional changes.
Validation of properties is moved from the import and allocation
functions into a separate function. This allows later separation of
modifier informations from the base struct.
This extension is required for the aquire and release barriers
to transfer the buffer ownership from and two an external queue.
This removes a warning from the validation layers.
We can increase the MAX_LATENCY again if we increase the amount of
buffers when we are using a small buffer.
Normally we ask for 4 * quantum-limit as the buffer. This should be good
to use 1 buffer and quantum-limit as the quantum with enough headroom
to not run out of buffers.
If we are however using less buffer-frames we need to be careful and
allocate an extra buffer. Imagine using a buffer of 4096 frames, we can
support a quantum of up to 2048 frames if we use 2 buffers.
See #3744
Half of the buffersize is not enough to support as a max-quantum, we
need to divide by (4 * frame_scale) to allow some headroom and account
for the DSD scaling. We do the same calculation to suggest a buffer size
using the quantum-limit.
See #3744
When the filter has no format property, just enumerate all possible
framerates. Handle error case where the filter has the wrong type.
Makes gst-launch gstpipewiresrc ! video/x-raw ! fakesink work.
See #1793
Actually count the number of frame fractions we add. If we added 0, we
don't have any supported framerate that intersects with the filter and we
try the next frame size.
See #1793
Not waiting for HFP when no HFP backend should be checked via
adapter_connectable_profiles in spa_bt_device_check_profiles where the
relevant logic is.
Cleanup by moving the checks there.
