- e7078e842 hevcdsp: add x86 SIMD for MC
- VAAPI VP8 decode hwaccel (currently under review: http://ffmpeg.org/pipermail/ffmpeg-devel/2017-February/thread.html#207348)
- Removal of the custom atomic API (5cc0057f49, see http://ffmpeg.org/pipermail/ffmpeg-devel/2017-March/209003.html)
-- Use the new bitstream filter for extracting extradata (see 8e2ea69135 and 096a8effa3)
-- ADD_RES_MMX_4_8 in libavcodec/x86/hevc_add_res.asm probably needs updating (see 589880710)
+- Use the new bitstream filter for extracting extradata (8e2ea69135 and 096a8effa3, see https://ffmpeg.org/pipermail/ffmpeg-devel/2017-March/209068.html)
- Read aac_adtstoasc extradata updates from packet side data on Matroska once mov and the bsf in question are fixed (See 13a211e632 and 5ef1959080)
+- new bistream reader (see http://ffmpeg.org/pipermail/ffmpeg-devel/2017-April/209609.html)
Collateral damage that needs work locally:
------------------------------------------
- Merge proresenc_anatoliy.c and proresenc_kostya.c
- Remove ADVANCED_PARSER in libavcodec/hevc_parser.c
- Fix MIPS AC3 downmix
+- hlsenc encryption support may need some adjustment (see edc43c571d)
Extra changes needed to be aligned with Libav:
