* commit 'd7d6efe42b0d2057e67999b96b9a391f533d2333': h264: check sps.log2_max_frame_num for validity mov: validate number of DataReferenceBox entries against box size mov: compute avg_frame_rate only if duration is known flac: change minimum and default of lpc_passes option to 1 Conflicts: libavcodec/h264_ps.c libavformat/mov.c Merged-by: Michael Niedermayer <michaelni@gmx.at>
