[gst-devel] What is the proper pipeline for YouTube video playback?

[Aurelien Grimaud]

Hi,
If you want to know what is used by playbin2, use the -v option ...

gst-launch-0.10 -v  playbin2 
uri="rtsp://rtsp2.youtube.com/CiQLENy73wIaGwnYRKJ3bPTBdBMYESARFEgGUghzdGFuZGFyZAw=/0/0/0/video.3gp"

Then you see this is mpeg4 ...

So the correct pipeline is
gst-launch-0.10 -v  rtspsrc 
location="rtsp://rtsp2.youtube.com/CiQLENy73wIaGwnYRKJ3bPTBdBMYESARFEgGUghzdGFuZGFyZAw=/0/0/0/video.3gp" 
! rtpmp4vdepay ! ffdec_mpeg4 ! xvimagesink

I did try playbin myself before and it does give me video, however, I can't use that approach.  Do you know a way to get the pipeline for this case?  Thanks a lot.
