Does 'file' work for .nuv files?  It doesn't on Debian unstable.

"nuvinfo /path/to/foo.nuv" will tell you lots of stuff about the nuv file,
including the fourcc values for video and audio.  The values I have are
1096237394 = 0x41574152 = 'RAWA' = raw audio
1162690892 = 0x454d414c = 'LAME' = MP3 audio
1196444242 = 0x47504a52 = 'RJPG' = RTjpeg
1482049860 = 0x58564944 = 'DIVX' = MPEG4
I would assume there's some other value for MPEG2.

The default nuvinfo shows only the first (int) values.  I've attached a
patch to make it print the hex and character values.
