The problem in this case is that the media types map roughly to the
container formats. However, the codecs are what really count. For
example, MPEG-4 Simple Profile, MPEG-4 Advanced Simple Profile and H.
264 all live in the video/mp4 container. However, support for these
codecs and their zillion subprofiles varies. (Yet another example why
optional profiles in spec are bad for interop. The profiling of the
MPEG-4 video stuff is worse than any Web spec "Mobile Profile".)
