Comment:
The reason for the behaviour you are observing is that the video stream's
disposition is "attached pic" when demuxing from the mp3, but not when you
are demuxing it from jpeg (the disposition gets lost when muxing into
jpeg). When muxing a stream with disposition "attached pic" into mp4, only
a few image codecs are allowed (by our muxer, wouldn't be surprised if the
format allowed more), H.264 is not among them, leading to the error
message.
You can unset the disposition by adding "-disposition:v -attached_pic" to
your commandline.
