If you use playbin and glimagesink, it should handle this and not use a lot of
CPU. You need GIT master though.

Example with my phone, 720p30 without zerocopy uses 100% CPU (well, it doesn't
play in real time in any case). With the recent zerocopy work it plays smoothly
and uses 4% CPU or something around that.


Also by using zerocopy, you don't care about the actual color format used. It's
just OpenGL in the end then.

There are already quite a few GStreamer applications in the app store ;) Does
that answer your question?
