I have some clips which audio is shorter than video. The player can't change
state from PLAYING to PAUSE state after audio is finish and video is playing.
The root cause is audio sink hasn't received GAP event and can't finish preroll
and video sink changed to PAUSE state.
It is ok if send EOS when audio finish, but streamsynchronizer send GAP event.
I haven't seem streamsynchronizer send GAP event when player change state from
PLAYING to PAUSE state.
Can give me some advice or do you need more information?
