Thanks for the clarification.

*I* think so, yes. It is not a continuation of a previous stream, but something
new starts now or there was a "gap" (seek). In both cases you would have to
reinit decoders, etc. If that's what the ONVIF spec means, I don't know.

I would recommend bringing this up to the ONVIF people and request
clarification about this first before we patch in any things that we might have
to remove again later. It seems underdefined and weird as is.


The certification tool also seems to not properly check that if I understand
you correctly. So there's clearly some clarification needed, and fixup of the
certification tool probably.
