[Michael Niedermayer]

ffmpeg | branch: master | Michael Niedermayer <michaelni at gmx.at> | Sat Jan 14 18:38:35 2012 +0100| [0d5c810bd59abed01f8e70ee956897599eaaea25] | committer: Michael Niedermayer

mpeg12dec: check uppercased codec_tag.

We do this for all other codec_tag checks in mpegvideo*/h26*
doing it here too makes the code more consistent.
