ffmpeg | branch: master | Anton Khirnov <anton at khirnov.net> | Tue Nov 26 11:07:22 2013 +0100| [873379939299046b30cdec26a837171029ef8099] | committer: Anton Khirnov

h263dec: sanitize a condition.

Call ff_mpeg4_decode_picture_header() only when the decoder has the
MPEG4 codec id, not based on a vaguely related value of h263_pred.
