The h264parse element shouldn't be needed, but maybe that would
require changes in gst-openmax.

I find this line strange:

video/x-raw-yuv, width=(int)320, height=(int)240,
format=(fourcc)0x00000000, framerate=(fraction)25/1

I don't think gst-openmax is detecting the color format properly,
should be easy to check what format OpenMAX IL is returning, and match
it to the GStreamer caps.

Cheers.
