Video capture PipeWire: always capture latest processed buffer ...
Both CaptureFrame() and ProcessBuffer() hold a lock over the frame queue
and it happens that one waits for the other, causing unnecessary delays
since we already work with a queue having two frames, but this way we
don't really need a queue. Instead, keep reference to the last processed
buffer, which we will always use in CaptureFrame() and update it every
time at the end of ProcessBuffer(). This avoid unnecessary waiting for
the lock over the queue to be released.
