Merge remote-tracking branch 'qatar/master'
* qatar/master: (29 commits) sbrdsp.asm: convert all instructions to float/SSE ones. dv: cosmetics. dv: check buffer size before reading profile. Revert "AAC SBR: group some writes." udp: Print an error message if bind fails cook: extend channel uncoupling tables so the full bit range is covered. roqvideo: cosmetics. roqvideo: convert to bytestream2 API. dca: don't use av_clip_uintp2(). wmall: fix build with -DDEBUG enabled. smc: port to bytestream2 API. AAC SBR: group some writes. dsputil: remove shift parameter from scalarproduct_int16 SBR DSP: unroll sum_square rv34: remove dead code in intra availability check rv34: clean a bit availability checks. v4l2: update documentation tgq: convert to bytestream2 API. parser: remove forward declaration of MpegEncContext dca: prevent accessing static arrays with invalid indexes. ...
