* qatar/master: (27 commits) ac3enc: fix LOCAL_ALIGNED usage in count_mantissa_bits() ac3dsp: do not use the ff_* prefix when referencing ff_ac3_bap_bits. ac3dsp: fix loop condition in ac3_update_bap_counts_c() ARM: unbreak build ac3enc: modify mantissa bit counting to keep bap counts for all values of bap instead of just 0 to 4. ac3enc: split mantissa bit counting into a separate function. ac3enc: store per-block/channel bap pointers by reference block in a 2D array rather than in the AC3Block struct. get_bits: add av_unused tag to cache variable sws: replace all long with int. ARM: aacdec: fix constraints on inline asm ARM: remove unnecessary volatile from inline asm ARM: add "cc" clobbers to inline asm where needed ARM: improve FASTDIV asm ac3enc: use LOCAL_ALIGNED macro APIchanges: fill in git hash for av_get_pix_fmt_name (0420bd7). lavu: add av_get_pix_fmt_name() convenience function cmdutils: remove OPT_FUNC2 swscale: fix crash in bilinear scaling. vpxenc: add VP8E_SET_STATIC_THRESHOLD mapping webm: support stereo videos in matroska/webm muxer ...
