That approach has a problem that I do not know the buffer size before
decoding first frame of the stream. The OMX component on the other hand
does not start decoding before it has buffers allocated.

So, how do you do it in gst-dsp if you do not know the width & height of
the clip ? Can it decode without having the buffers set ?
