Hi Edward: Thanks for your suggestion. I am preparing youtube playback on a device eventually. Since on the device playbin is not supported, I need to figure out the actual pipeline and write in software.  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.
