* qatar/master: bitstream: Properly promote av_reverse values before shifting. libavutil/swscale: YUV444P10/YUV444P9 support. H.264: Fix high bit depth explicit biweight h264: Fix 10-bit H.264 x86 chroma v loopfilter asm. Replace DEBUG_SEEK/DEBUG_SI + av_log combinations by av_dlog. Update copyright year for ac3enc_opts_template.c. adts: Adjust frame size mask to follow the specification. movenc: Add RTP muxer/hinter options movenc: Pass the RTP AVFormatContext to the SDP generation rtspenc: Add RTP muxer options rtspenc: Add an AVClass for setting muxer specific options rtpenc_chain: Pass the rtpflags options through to the chained muxer rtpenc: Declare the rtp flags private AVOptions in rtpenc.h sdp: Reindent after the previous commit rtpenc: MP4A-LATM payload support avoptions: Add an av_opt_flag_is_set function for inspecting flag fields sdp: Allow passing an AVFormatContext to the SDP generation mov: Fix wrong timestamp generation for fragmented movies that have time offset caused by the first edit list entry. mpeg12: more advanced ffmpeg mpeg2 aspect guessing code. swscale: split YUYV output out of yuv2packed[12X]_c().
