#6990: Encoding is corrupted when using d3d11va hwaccel and d3d11 as hardware output format --------------------------------------+--------------------------------- Reporter: jamrial | Owner: Type: defect | Status: new Priority: normal | Component: avcodec Version: git-master | Keywords: d3d11 Blocked By: | Blocking: Reproduced by developer: 0 | Analyzed by developer: 0 --------------------------------------+--------------------------------- http://samples.ffmpeg.org/benchmark/testsuite1/matrixbench_mpeg2.mpg {{{ ./ffmpeg -hwaccel d3d11va -hwaccel_output_format d3d11 -i matrixbench_mpeg2.mpg -an -c:v h264_amf out.mkv }}} The above produces a stream with tons of stutter, and a different result each time (varying checksum). Using nv12 instead as output format fixes it. I'm using an HD7950 on Windows 10 x64 (version 1709, Fall Creators build), driver version 17.12.1 I don't know if this also happens with other GPU vendors as i can't test, and of course software encoders will not accept d3d11 pixfmt as input. -- Ticket URL: <https://trac.ffmpeg.org/ticket/6990> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#7088(ffmpeg:new): Dropped video frames from iOS 11 Screen Record Videos lead to an Unsynced video

#7088: Dropped video frames from iOS 11 Screen Record Videos lead to an Unsynced video -------------------------------------+------------------------------------- Reporter: jonlam92 | Type: defect Status: new | Priority: important Component: ffmpeg | Version: 3.2.4 Keywords: ios 11, | Blocked By: iphone, quicktime, ffmpeg, | Reproduced by developer: 0 avconv, negative start timestamp, | map, mp4, mpeg, copy | Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- It seems like ffmpeg does not know how to handle videos that were recorded on iOS 11 through the native screen recording functionality. We were taking the video stream and copying the second audio stream (from the microphone) and stitch it together so web players would be able to handle the audio portion properly. We discovered that frames were dropped at the beginning of the converted video, but the audio still began on time. It seems like everything before the 2nd keyframe is dropped, as it can't locate the first keyframe. We believe this occurs due to a negative start timestamp on the video. How to reproduce: {{{ ffmpeg -i input.mp4 -acodec copy -vcodec copy -map 0:v:0 -map 0:a:1? -f mp4 output.mp4 }}} Output from `ffmpeg -i input.mp4` {{{ ffmpeg version 3.4.2 Copyright (c) 2000-2018 the FFmpeg developers built with Apple LLVM version 9.0.0 (clang-900.0.39.2) configuration: --prefix=/usr/local/Cellar/ffmpeg/3.4.2 --enable-shared --enable-pthreads --enable-version3 --enable-hardcoded-tables --enable- avresample --cc=clang --host-cflags= --host-ldflags= --disable-jack --enable-gpl --enable-libmp3lame --enable-libx264 --enable-libxvid --enable-opencl --enable-videotoolbox --disable-lzma libavutil 55. 78.100 / 55. 78.100 libavcodec 57.107.100 / 57.107.100 libavformat 57. 83.100 / 57. 83.100 libavdevice 57. 10.100 / 57. 10.100 libavfilter 6.107.100 / 6.107.100 libavresample 3. 7. 0 / 3. 7. 0 libswscale 4. 8.100 / 4. 8.100 libswresample 2. 9.100 / 2. 9.100 libpostproc 54. 7.100 / 54. 7.100 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'input.mp4': Metadata: major_brand : mp42 minor_version : 1 compatible_brands: mp41mp42isom creation_time : 2018-03-16T18:56:20.000000Z Duration: 00:03:54.07, start: -0.015941, bitrate: 2456 kb/s Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuvj420p(pc), 1080x1920, 2319 kb/s, 23.03 fps, 60 tbr, 600 tbn, 1200 tbc (default) Metadata: creation_time : 2018-03-16T18:56:21.000000Z handler_name : Core Media Video Stream #0:1(und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 2 kb/s (default) Metadata: creation_time : 2018-03-16T18:56:21.000000Z handler_name : Core Media Audio Stream #0:2(und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 103 kb/s (default) Metadata: creation_time : 2018-03-16T18:56:21.000000Z handler_name : Core Media Audio }}} Output of this video has dropped video frames (approximately 10 seconds worth), while keeping the audio. This leads to an unsynced video. Even with flags like `-copyts` and other fixes we found online, we still ended up with dropped frames at the start of the video, i.e. a black screen. We tried a fork of ffmpeg called libav, which seems to handle this file properly and doesn’t drop the frames at the start of the output video, between the first and second keyframe.

The contents should contain "Apple ProRes 422(LT)" for the video stream, and "pcm_s24le" for the audio streams, plus a "tmcd" timecode. This particular file will open and play with quicktime without audio, so something in one or both of the audio tracks is messed up. Oddly enough VLC for MacOS manages to open and play with audio. With ffmpeg I get the following: [mov,mp4,m4a,3gp,3g2,mj2 @ 0x7f426c0093e0] Invalid sample_count=-1744855732 [mov,mp4,m4a,3gp,3g2,mj2 @ 0x7f426c0093e0] error reading header This is using ffmpeg-3.1.5. I can build and test with current head if that would seem to make any difference. The file is rather large (368G) so let me know how I can submit a chunk that is just large enough to provide enough info to work with -- Ticket URL: <https://trac.ffmpeg.org/ticket/5911> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
