ts video pipe
Locked
 
|
Hi,
I try to figure that out from the net, but with no success :(, so I gonna ask here (I am really a newby at gstreamer): I have a file containing only the ts video stream (PID 0x1111 in that special case), which is an mpeg2 stream from dvb-t. When I try to play that with mplayer ( SVN-r1.0~rc3+svn20090426-4.4.3 - Ubuntu 10.4) It says (see 1-- below) and the video is displayed. So I tried to play it with gstreamer and it fails: --- snipp ------ gst-launch-0.10 -v filesrc location=Das\ Erste.ts ! mpegtsdemux name=demux demux.video_4369 ! mpeg2dec ! xvimagesink Setting pipeline to PAUSED ...

However, the pes transported within the ts packets carry all information for configuring the decoder correctly, as far as I know. So what is left to do is to demux the stream (here: get rid of the ts packaging) and feed it to the decoder, I guess. > try gst-launch filesrc ! mpegtsdemux es-pids=0x1111 ! mpeg2dec ! > xvimagesink Same output as before :-( I may be able to add the PMT and PAT, but they carry more information (Information for all 4 programs in the bouquet), which are not included into the stream. It would be best for me, if I do not have to reconfigure the pipe for every stream with different PID information, as this makes the call of the stream kind of cumbersome. I do not believe I will be able to rearrange the PAT/PMT information :-/. Actually the audio is not integrated as I would love to see a picture in first place. -t ------------------------------------------------------------------------------ This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?
