ffmpeg | branch: master | Vittorio Giovara <vittorio.giovara at gmail.com> | Wed Mar 11 20:43:59 2015 +0000| [5a0e953c2465be9d449d5f523c3d3e2b886910b2] | committer: Vittorio Giovara

mjpeg: Mark decoder family as thread safe

No global variables are used and the VLC tables are allocated without
static elements. This will allow using a JPEG decoding context within
other decoders.
