Comment (by jasaw):
It appears that whenever the zerocopy condition in omx.c is satisfied
(contiguous planes and stride alignment), the call to OMX_EmptyThisBuffer
hangs. 1280 x 720 resolution images captured from the Pi camera happens to
meet that condition.
This explains why it works when zerocopy is disabled.
