What the hell is that no-resurect-buf property. Are you sure you should not be
filing bugs to the people patching your GStreamer instead ? This looks like a
downstream fork of GStreamer.

Upstream gst-omx have no support for DMABuf (and that would be a stretch since
OMX spec has no support for DMABuf either). Is there any issue here that is not
specific to your vendor fork ?
