GStreamer would find out if there's any conversion needed (of the elements are implemented properly). Maybe you should give a try to gst-omapfb which renders directly into the framebuffer into a YUV overlay. Unfortunately the OMAP3 display subsystem doesn't support I420 so you would need some conversion for sw codecs. Or you can try to use the DSP accelerated codecs which have an accelerated converter. > ?????????????? I want to improve performance on beagle board.

I know FFmpeg guys have been able to decode 720p videos smoothly on the beagleboard so it's definitely possible. You just need to plug the right pieces :) -- Felipe Contreras
