GNU libmagic used by the command line utility "file" can be used for
content-type sniffing as well.

The spec has a note saying "I'd like to add types like MPEG, AVI,
Flash, Java, etc, to the above table."
http://www.garykessler.net/library/file_sigs.html seems to have an
up-to-date list of many file signatures, including SWF (43 57 53), AVI
(52 49 46 46 xx xx xx xx 41 56 49 20 4C 49 53 54), Java class files
(CA FE BA BE), MPEG files (00 00 01 Bx), and so on.
