My guess is that the following is relevant:

https://code.mythtv.org/trac/ticket/12010

I can't say that I understand the discussion in that trac thread, but it
seems that there are ways of encoding H.264 such that there are no
I-frames, but rather IDR frames (instantaneous coding refresh).

>From my brief research (reading various Wikipedia pages) the two serve
similar purposes, but they have different semantics, and mythcommflag
does not seem capable of dealing with the IDR frames in H.264 streams.
