Merge remote-tracking branch 'qatar/master'
* qatar/master: (24 commits) utils: Drop pointless '#if 1' preprocessor directive. ac3enc: remove empty ac3_float function that is never called ac3enc: split templated float vs. fixed functions into a separate file. ac3enc: dynamically allocate AC3EncodeContext fields windowed_samples and mdct ac3enc: use function pointer to choose between AC-3 and E-AC-3 header output functions. Roll back 4:4:4 H.264 for now Needs some ARM/PPC asm modifications. Fix SVQ3 after adding 4:4:4 H.264 support H.264: fix CODEC_FLAG_GRAY 4:4:4 H.264 decoding support h264_parser: Fix whitespace after previous change. h264_parser: Fix behaviour when PARSER_FLAG_COMPLETE_FRAMES is set. wav: remove an invalid free(). lavf: initialise reference_dts in av_estimate_timings_from_pts. h264: don't be so picky on decoding pps in extradata. avcodec.h: add or elaborate on some documentation comments. h264: change a few comments into error messages ac3dec: fix doxy-style for comment ("///>" should be "///<" instead). img2: add .dpx to the list of supported file extensions. ffv1: fix undefined behavior with insane widths. ARM: jrevdct_arm: simplify stack usage ... Merged-by: Michael Niedermayer <michaelni@gmx.at>
