X-Git-Tag: 1.19.3~493^2~775

pipeline: Allow up to 2 seconds queueing in the playsink video queue

In playsink the default video queue max size is 3 buffers, which is
sometimes not enough for our use case.

Allow up to 2 seconds of buffered data, giving us more time to do
the transition between clips, and thus avoiding dropping frames in
the sink when bringing up new clip takes too much time.
