No, this is raw decode without yuv2rgb conversion or display "overhead",
or audio. Still, looks like things are in the realm of possibility.
Chih-Chung, I assume you're using libtheora 1.0a7. Could you re-run the
decoding tests with dump_video from http://svn.xiph.org/trunk/theora-exp/ ?
That should be instructive.
Can the camera hardware generate YUV?
