Because we need omx functionality. I guess it would be possible to
forget about omx base classes and re-implement all the omx stuff
inside audio and video base sinks, but I don't think we'll get any
advantage from that. But then again, I haven't really spent that much
time in sources and sinks; only encoders and decoders.

I'm not sure I get the question. Are you asking if there's any work on
a clock in gst-openmax? If so, not AFAIK.

Cheers.
