Hmm, it seems that I was not too mad when I wrote the patch because no change
seems to be needed after all. :)

The check is:
!(h264parse->state & GST_H264_PARSE_STATE_VALID_PICTURE_HEADERS)

which means, "no SPS nor PPS received so far". I have not used
GST_H264_PARSE_STATE_VALID(), which checks for all the supplied bits in state.

However, the troublesome case is
if alignment=au and (SPS or PPS was received) and we got a slice too. We should
reset the frame only if the broken NAL is a slice.
