Mark Harris	ae4323548a	avfilter/vf_fade: fix start/duration max value A fade out (usually at the end of a video) can easily start beyond INT32_MAX (about 36 minutes). Regression since `d40dc64173`.	6 years ago
Paul B Mahol	e96742dd3b	avfilter/af_afftfilt: use first input frame timestamp	6 years ago
Akemi	233cd89056	lavc/videotoolbox: Fix cropping with HEVC and H264 videos videotoolbox returns an already cropped stream which led to double cropping. this issue was introduced with the refactor of the cropping mechanism in commit `07596e4` for h264 and `000fb61` for HEVC. to fix this we set the cropping of the frame and the output frame to 0.

Andreas Rheinhardt	ee47ac97d7	cbs_h2645: Improve performance of writing slices Instead of using a combination of bitreader and -writer for copying data, one can byte-align the (obsolete and removed) bitreader to improve performance. With the right alignment one can even use memcpy. The right alignment normally exists for CABAC and hence for H.265 in general. For aligned data this reduced the time to copy the slicedata from 776520 decicycles to 33889 with 262144 runs and a 6.5mb/s H.264 video. For unaligned data the number went down from 279196 to 97739 decicycles. Signed-off-by: Mark Thompson <sw@jkqxz.net>	6 years ago

Marton Balint	6c2a7a8e9a	avfilter/vf_framerate: factorize SAD functions which compute SAD for a whole frame Also add SIMD which works on lines because it is faster then calculating it on 8x8 blocks using pixelutils. Signed-off-by: Marton Balint <cus@passwd.hu>	6 years ago
Andreas Rheinhardt	6df9020f45	cbs_mpeg2: Improve performance of writing slices Instead of using a combination of bitreader and -writer for copying data, one can byte-align the (obsolete and removed) bitreader to improve performance. One can even use memcpy in the normal case. This improved the time needed for writing the slicedata from 33618 to 2370 decicycles when tested on a video originating from a DVD (4194394 runs).

Mark Wu	10bc4c3a7d	avcodec/hevcdec: fix non-ref frame judgement After inspecting the source code of x265, mpv and ffmpeg, I've found that ffmpeg mistakenly regards EVC_NAL_BLA_N_LP and HEVC_NAL_IDR_N_LP as non- reference frames, which are acutally reference frames according to the specification in x265, and drops them. This patch should address the problem. I have tested it with mpv. Signed-off-by: Mark Wu <wfwf1997@gmail.com> Signed-off-by: James Almer <jamrial@gmail.com>	6 years ago

Martin Vignali	ff3b4f91cd	avcodec/prores_aw : add support for prores 444 with alpha only 16b alpha is supported (not 8 bits) following official encoder, alpha data doesn't impact yuv plane quality. So the alpha data encoding is done after the yuv part. It's also avoid to loose quality in yuv part when alpha is not uniform. the alpha encoding funcs is mainly take from prores_ks encoder, except for the alpha data reorganization	6 years ago

Andreas Rheinhardt	8d1cf2d894	cbs_h264: Fix handling of auxiliary pictures The earlier code used the most recent non-auxiliary slice to determine whether an auxiliary slice has the syntax of an IDR slice, even when the most recent slice was from a slice of a redundant frame.
