Comment (by Balling):
>consider a H.264 track whose SPS/PPS are only transmitted out of band and
that doesn't have IDR frames, but only I frames with recovery point SEI
messages as keyframes
Well, such a frame is not a valid stream per the spec. Each stream should
start with IDR. Anyway, I see nowadays it is almost always inserted.
