I strongly dislike binary data in string constants.
Also, using AV_RB32 would be more readable anyway.

And I think it is too little to justify this
probe score.
Even more so since there's another 4 bytes directly
following that the read_header functions checks for
validity.
tools/probetest is a good idea to try.

Looks like there should be one space more.

You should use url_feof, so that it gets updated if the file is extended
later. Though I admit that for this format things will probably be
broken at that point already.
