Add a new pw_stream_set_param() method to configure a param on the
adapter.
This can be used to override the volume param for the adapter, for
example.
When the node receives a set_param Props, it calls the follower
set_param implementation. If that one calls set_param again on the
adapter, discards the original set_param.
This makes it possible for the follower to intercept the Props param and
set a modified version on the converter. This can be used to intercept
volume changes.
Make the XOpenDiplay call failure print an info message instead of a
warning. We usually ignore this error in the config file. Add a
suggestion for how to fix this issue in the info log.
Fixes#2918
As soon as we find a failed match, break the loop so that we don't check
uselessly the other properties but that we proceeed to the next set of
properties to match.
Add a condition to load the session manager and pipewire-pulse. This
makes it possible to disable the exec based on a context.properties
override.
Add a condition to load the access module. This makes it possible to
disable the default access behaviour and override with a custom one.
Fixes#3160
When a sink contributing to an ISO CIG does not have data, output
silence for it, as long as at least one sink in the CIG is running.
Only if writes to sockets fail, pause all streams to reset
synchronization.
This way we write exactly the same number of packets for each CIS at the
same time, which probably is the best tested configuration in BT
adapters and devices. We also don't then have to pause output if some
sinks are not running or miss their timing, as we generate silence on
the fly.
When using iso-io, have it initialize the codec instance, and have
media-sink uses that instance, so that silence and actual audio are
encoded with the same codec.
Always make peers of non-passive links runnable, even if we already
visited the peer node. This makes non-passive links between drivers set the
drivers to runnable. (midi-bridge, source to sink). It also makes nodes
collected from the (link-)group runnable when they are linked together.
To calculate the runnable state of the other nodes, only start from
non-driver runnable nodes (like we already did when following links).
This makes a link from echo-cancel-source to echo-cancel-sink activate
the echo-canceler chain instead of staying idle.
Actually convert the aec_args argument to something that the
echo-canceler will understand. Add the beamforming and mic-geometry
and target_direction properties.
This was introduced in 4faa28fd96 in order to correctly map the time
from the stream. From d52df30c88 on, however, the clock switched to
monotonic time, which does not need the extra-offset.
Disable `clock_reset()` for now but leave it in place so we can easily
reenable it once we use the stream time again.
This fixes video recording in Cheese and similar apps.

Use the "high-reliability" values for QoS parameters instead of the
low-latency ones. Under some condition BlueZ does not pass on the
endpoint QoS values to us, in which case we may end up selecting bad
latency.
Determine correctly if we are resampling, and have the associated delay.
Add off-by-one sample adjustment to the resampling delay, which seems to
correctly align the resampled audio with non-resampled.
A non-passive link between the driver and itself should make the driver
active as well.
This makes the midi-bridge running when linking its ports. It also activates
a sink when its monitor ports are connected to its playback ports.
Fixes#3153
Make the channels configurable for capture, source, playback and
sink streams. The playback and sink stream need to have the same number
of channels but the layout can be different.
Use init2 of the echo-cancel plugin when available to pass this info
around. The echo-canceler will then further adjust the settings to make
things work.
The WebRTC echo canceler can support different rates and channels for
the record, out and playback streams.
Add a new method to pass this config to the echo-canceler.
Explicitly make the driver runnable when we add a runnable node to it.
We have to do this because the runnable node might not be directly linked
to this driver.
In the case of the echo-canceler, for example, a playback stream
can be linked to the sink before the echo canceled virtual sink.
All echo-cancel nodes are added to a source driver, which would not be
activated because there is no direct path from the playback stream
to the source river.
Fixes#3145
Resynchronize ISO streams on playback (re)start, so the stream positions
are aligned immediately. This is better than relying on rate matching
to correct any offsets.
Use a separate variable to hold the maximum amount of drift we allow
between driver and follower. Ensure this value is smaller than the max_error
and period size so that we have at most 1 period of drift.
Don't reschedule a timeout when we have less samples available than the
target but only reschedule when we have less that the required amount we
need to read. This ensures that we hover around the target level and the
timeouts/rate matching adapts correctly. Previously we would only rate
match if the have at least the target amount of samples, which would
then always result in a possitive rate adjustment and cause drift.
For capture, make sure that there is at least 32 samples of headroom
when we are not using IRQ mode to handle jitter in the timer wakeup.
For capture of batch devices this results in (for a 1024 quantum) a
target buffer fill level of 1024 + 512, and we will read if there are at
least 1024 samples available.
For non-batch devices we aim for a target buffer fill level of 1024 + 32
and read if there are at least 1024 samples available.
Emit BAP device set nodes, which the session manager can use to combine
the sinks/sources of a device set to a single sink/source.
Emit the actual sinks/sources with media.class=.../Internal to hide them
from pipewire-pulse.
Add separate device set routes to the set leader device. Other routes
of the set members will be marked as unavailable when the set is active.
Accordingly, return failure for attempts to set these unavailable
routes, so that volumes etc. of the "internal" nodes are only controlled
via the device set route.
