Merge remote-tracking branch 'qatar/master'
* qatar/master: h264: drop ff_h264_ prefix from static function ff_h264_decode_rbsp_trailing() h264: Make ff_h264_decode_end() static, it is not used externally. output-example: K&R formatting cosmetics, comment spelling fixes avf: make the example output the proper message avf: fix audio writing in the output-example mov: don't overwrite existing indexes. lzw: fix potential integer overflow. truemotion: forbid invalid VLC bitsizes and token values. truemotion2: handle out-of-frame motion vectors through edge extension. configure: Check for a different SDL function Conflicts: configure doc/examples/muxing.c libavcodec/truemotion2.c Merged-by: Michael Niedermayer <michaelni@gmx.at>
