Add spa_json_begin_array/object to replace
spa_json_init+spa_json_begin_array/object
This function is better because it does not waste a useless spa_json
structure as an iterator. The relaxed versions also error out when the
container is mismatched because parsing a mismatched container is not
going to give any results anyway.
Round down the size and avail to the frame size to make sure we always
send aligned frames.
When we don't have the required size, set the buffer to 0 but still send
whatever we have in the ringbuffer or else it stays there until some
unknown time when it gets flushed out again with new data.
Remove some includes of private.h
Add some methods to get the mempool of client and context so that we can
remove direct access.
Move some things around.
Use methods to get pw_loop variables.
See #3243
Set the module to NULL when unloading. Check if the module exists before
attempting to unload it.
Flush any pending invokes on the mainloop before destroying the impl.
Fixes#3199
Intercept the stream volume/mute and set it as the remove volume/mute.
Listen for remote volume/mute changes and set this as the local stream
volume. Make sure the adapter is using 1.0 software volume but reports
the real channelVolume of the remote stream.
We are not allowed to call pipewire methods from any other thread than
the main thread so use invoke to schedule a module unload from the
pulseaudio thread.
Fixes some infinite loops when the work-queue list gets corrupted.
Pulseaudio requires that we call pa_stream_write with a multiple
of frame_size bytes. Because our ringbuffer is a power of two, this
might cause problems at the edge of ringbuffer where a sample is
split between the end and beginning of the ringbuffer.
Avoid this by letting pulse allocate a buffer instead and memcpy
the requires samples into it.
Fixes multichannel output on module-pulse-tunnel.
So that all nodes attach to some driver to be scheduled.
For the virtual sink/sources this is a normal thing and we can remove
the custom settings.
For normal stream, this now makes it possible to link pw-play directly
to pw-record and have it transport data.
Fixes#1761
Track the end-to-end latency of the stream and use that to drive
the resampler.
Hard reset the ringbuffer when under/overflow happens so that we
can recover quickly.
See #2230
Assign half the latency to the internal ringbuffer and half on the
network and remote end.
Use a dll to calculate the drift from our target ringbuffer fill
level and use the stream rate property to driver the resampler.
This should reduce uncontrolled latency over the tunnel.
PulseAudio wants us to be a driver will pull requests from the remote
side. We would need to provide a clock based on the remote end and
also try to follow it when we are not a driver. It would be slightly
better because in the normal playback case we would be able to
avoid resampling. We might do this eventually.
For the modules that require a driver, don't add ourselves to
the pipewire.dummy group but instead just use the NODE_WANT_DRIVER
property to be assigned to a driver.
This makes it possible for the nodes to move to another driver than the
dummy driver (which has very high priority) and it avoids resampling in
cases where the nodes are linked to an audio source or sink.
