Description Yun Chao 2011-05-17 06:21:17 UTC 
I want to play a mkv file which contains a video stream, an audio stream and a dvd-subpicture stream. If I play these streams in different sink elements, it will wait preroll infinitely. A simple test script as following:

file location=test.mkv ! matroskademux name=demux demux.audio ! queue ! fakesink sync=true demux.video_00 ! queue ! fakesink sync=true demux.subtitle_00 ! queue ! fakesink sync=true

How can I play dvd-subpicture in mkv using different sink element of video stream?

Thanks.

The problem probably is, that the subpicture stream is a sparse stream and the sink does not pre-roll until the other queues are full. Does it work if you set sync=false and async=false on the subpicture sink?

It's really done. Thanks.
