#8070: mov demuxer is broken on fragmented MP4 files with multiple trun boxes per sidx entry -------------------------------------+------------------------------------- Reporter: dbuitenh | Owner: Type: defect | Status: new Priority: normal | Component: avformat Version: git- | Keywords: mov dash master | mp4 fmp4 Blocked By: | Blocking: Reproduced by developer: 0 | Analyzed by developer: 0 -------------------------------------+------------------------------------- Summary of the bug: FFmpeg makes the assumption that fragmented MP4 files will have exactly one 'trun' box per entry in the 'sidx' box (see here: http://git.videolan.org/?p=ffmpeg.git;a=blob;f=libavformat/mov.c;h=24de5429…) This is not the case and the spec explicitly allows multiple 'trun' boxes (chunks) per sidx entry. Other players, browsers, and demuxers handle this corectly. FFmpeg ends up resetting the PTS and DTS at each new trun box, resulting in repeated timestamps.

Also plays ok with VLC 3.0.3. {{{ ffmpeg version N-91646-g78d4b6bd43 Copyright (c) 2000-2018 the FFmpeg developers built with gcc 8.2.1 (GCC) 20180813 configuration: --enable-gpl --enable-version3 --enable-sdl2 --enable- fontconfig --enable-gnutls --enable-iconv --enable-libass --enable- libbluray --enable-libfreetype --enable-libmp3lame --enable-libopencore- amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libopus --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libtheora --enable-libtwolame --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxml2 --enable-libzimg --enable-lzma --enable-zlib --enable-gmp --enable-libvidstab --enable- libvorbis --enable-libvo-amrwbenc --enable-libmysofa --enable-libspeex --enable-libxvid --enable-libaom --enable-libmfx --enable-amf --enable- ffnvcodec --enable-cuvid --enable-d3d11va --enable-nvenc --enable-nvdec --enable-dxva2 --enable-avisynth libavutil 56. 19.100 / 56. 19.100 libavcodec 58. 23.100 / 58. 23.100 libavformat 58. 17.103 / 58. 17.103 libavdevice 58. 4.101 / 58. 4.101 libavfilter 7. 26.100 / 7. 26.100 libswscale 5. 2.100 / 5. 2.100 libswresample 3. 2.100 / 3. 2.100 libpostproc 55. 2.100 / 55. 2.100 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'tiger.mp4': Metadata: major_brand : iso5 minor_version : 1 compatible_brands: avc1iso5dsmsmsixdash encoder : Lavf56.40.101 Duration: 00:02:24.37, start: -0.046440, bitrate: 1093 kb/s Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 1280x720 [SAR 1:1 DAR 16:9], 5 kb/s, 25 fps, 25 tbr, 12800 tbn, 50 tbc (default) Metadata: handler_name : VideoHandler Stream #0:1(und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 0 kb/s (default) Metadata: handler_name : SoundHandler }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/7377> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
