-Subject: [PATCH] gst: Implement new pwaudio{src,sink} elements, based on
- GstAudioBase{Src,Sink}
-
-These are much more reliable elements to use for audio data.
-* GstAudioBaseSink provides a reliable clock implementation based
- on the number of samples read/written
-* on the pipewire side we make sure to dequeue, fill and enqueue
- a single buffer inside the process() function, which avoids
- underruns
-
-Both elements share a common ringbuffer that actually implements
-the pipewire integration.
-
-Upstream-Status: Denied
-See https://gitlab.freedesktop.org/pipewire/pipewire/merge_requests/140
