NOTE: AVC looks working fine. < this was wrong, I mixed with different input stream, this seems input dependent

This is related to extbrc:

This is regression between 20.2.1 and 20.3.0 msdk releases.

@jamesiwan : fyi

dvrogozh commented 3 years ago

This got fixed w/ 20.3.1 msdk release in a form of switching off MCTF. And updated package is available in the repositories.intel.com. For the sake of media-delivery this is enough to close the issue. We are awaiting for the msdk release update with re-enabled MCTF however.
