[gst-devel] Decodebin doesn't work whereas playbin works, why?

[Jens Persson]

Ok, but it might give you some more clues. Perhaps like this:

gst-launch rtspsrc location="rtsp://localhost/test.mp4" protocols=1 
name=d ! decodebin ! queue ! ffmpegcolorspace ! xvimagesink  d. ! 
decodebin ! queue ! audioconvert ! alsasink

I've never used rtsp before. :D
