Log: clarify which of the MPEG-4 video codecs is meant
-MP4V ISO MPEG4 Video +MP4V ISO MPEG4 Part 2 Video
Does this mean ISO MPEG4 Part 2 Advanced Simple Profile? Or are all profiles allowed and the rest just probably not supported by any given implementation?
I would say all are allowed, simply because the alternative is more work than any volunteer here is likely going to do. We already lacked one just writing this list ... Also this problem would apply to mpeg1/2 h264, h263, ... as well.
Does part 2 include all the ridiculous stuff like sprites?
