             Now I am working on a small project ,I want to make a small program based on gstreamer to play videos.At first it play well, but when I play HD video,says 720P,it not smooth.I know the gstreamer search software decoders first,then harware. But how can I appoint the priority of hardware and software??? I want hardware decoder first, software second . Thank all!

I dont think gstreamer searches software decoder s first and then hardware, it all depends on the RANK.
If you want gstreamer to change priority of certain decoder element, please assign higher RANK then other lower priority elements.
For this you need to make changes in your plugin source code and recompile.

So if you have say 2 plugins one software and other hadware, you can just remove/uninstall the software plugin library and that should work. But thats not a appropriate solution.
