问题
I'm trying to play a local mpeg2 TS file with gstreamer with this:
gst-launch filesrc location=open_season.mpg ! mpeg2dec ! xvimagesink
The first frame appears as big blocks of color and then stops. Any thoughts about what I'm doing wrong here? Does a -TS file need to be handled differently than this?
Here's the log:
$ gst-launch filesrc location=open_season.mpg ! mpeg2dec ! xvimagesink

I think first you should first try to play the file with the help of playbin2. If you are able to play it then u should use decodebin2 ,debug its output and construct your pipeline accordingly.
The syntax for playbin2 is as follows :-
gst-launch playbin2 uri = file:///home/user1031040/Desktop/file.mpg
The syntax for decodebin2 is as follows:-
gst-launch filesrc location = file.mpg ! decodebin2 ! autovideosink
