Your pipe may look like gst-launch dvbsrc ! mpegtsdemux name=demux demux.video_0040 ! queue ! mpegpsmux name=mux ! filesink demux.audio_0040 ! queue ! mux. So in your pipe only video pad of demux was linked with video pad of mux. You need to link both audio & video.

Juni 2011 10:28 An: 'Discussion of the development of and with GStreamer' Betreff: Converting MPEG-TS to MPEG-PS </div><div><div></div><div class="h5"> Hi, I have a problem for seeking in MPEG-TS-files (to slow) and want to convert a TS-Stream to PS. But it seems to be a little tricky to select the pids. My pipe looks like this: ‘gst-launch-0.10 dvbsrc pids=97:511:512 frequ….. ! mpegtsdemux es-pids=511:512 ! mpeg2dec ! filesink location=test.mpg’ The pids are: 97 = PMT, 511 = Video, 512 = Audio. But it doesn’t work. The file is always 0 Bytes long. Without converting, it’s a very simple pipe: ‘gst-launch-0.10 dvbsrc pids=97:511:512 frequ….. ! filesink location=test.mpg’ And it’s works very good. What to I wrong to convert the stream? Thanks’ a lot for helping!!
