This is indeed due to mpeg4videoparse but also to the video stream in question
which does not contain any config data.  And mpeg4videoparse by default drops
frames until it has valid config data (configurable with drop property), the
latter default behaviour stemming all the way back from bug #532723.

Given that avdec_mpeg4 still seems to manage without config that may or may not
be the best default behaviour (and not consistent across parsers so it seems).
