Commit has been updated as:

avformat/mp3dec: Recognize files start with LAME3.100 as mp3

A set of files begins with the following byte sequence.

00000000 4c 41 4d 45 33 2e 31 30 30 aa aa aa aa aa aa aa |LAME3.100.......|
00000010 aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa |................|
*

It seems they are encoded with lame, but missing header bytes at the
beginning. Chrome recognize these files as valid.
