I guess the format is not actually H264-ES but only contains it.
It would help to know what the format of the stream really is,
probably its detection should be prioritized over H264-ES.
-dumpstream should also work for getting us a sample of the problematic
stream so we can check what goes on and possibly improve
the H264-ES autodetection.
It might not be reproducible by playing the dumped file directly,
but it should be when piping the problematic file via a fifo
or stdin.
