#9814: time_scale / num_units_in_tick is not infinite precision -------------------------------------+------------------------------------- Reporter: Balling | Type: defect Status: new | Priority: normal Component: | Version: git- undetermined | master Keywords: | Blocked By: Blocking: | Reproduced by developer: 1 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: as you can read here https://www.ffmpeg.org/ffmpeg- bitstream-filters.html#h264_005fmetadata H.264 has time_scale / num_units_in_tick in the VUI parameters. That is how one writes frame rate (besides timing SEI that is) in Annex B files. The problem is that (not touching very broken mkv here with only ms precision and only PTS in the form of duration, no DTS) when you go to mp4 you are supposed to make it CFR and use the nice tbn. But even if you will use vfrdet on annex b file it will not be CFR. This sample in fact has even fixed_frame_rate_flag set! So this is a bug, ffplay also cannot even seek in this annex b file! Sample is here: https://github.com/wang-bin/QtAV/files/1132086/example.zip How to reproduce: {{{ ffmpeg -i example.h264 -vf vfrdet -f null NUL ffmpeg version N-107098-g4d45f5acbd-20220613 Copyright (c) 2000-2022 the FFmpeg developers built with gcc 11.2.0 (crosstool-NG 1.24.0.533_681aaef) configuration: --prefix=/ffbuild/prefix --pkg-config-flags=--static --pkg-config=pkg-config --cross-prefix=x86_64-w64-mingw32- --arch=x86_64 --target-os=mingw32 --enable-gpl --enable-version3 --disable-debug --enable-shared --disable-static --disable-w32threads --enable-pthreads --enable-iconv --enable-libxml2 --enable-zlib --enable-libfreetype --enable-libfribidi --enable-gmp --enable-lzma --enable-fontconfig --enable-libvorbis --enable-opencl --disable-libpulse --enable-libvmaf --disable-libxcb --disable-xlib --enable-amf --enable-libaom --enable- libaribb24 --enable-avisynth --enable-libdav1d --enable-libdavs2 --disable-libfdk-aac --enable-ffnvcodec --enable-cuda-llvm --enable-frei0r --enable-libgme --enable-libass --enable-libbluray --enable-libjxl --enable-libmp3lame --enable-libopus --enable-librist --enable-libtheora --enable-libvpx --enable-libwebp --enable-lv2 --enable-libmfx --enable- libopencore-amrnb --enable-libopencore-amrwb --enable-libopenh264 --enable-libopenjpeg --enable-libopenmpt --enable-librav1e --enable- librubberband --enable-schannel --enable-sdl2 --enable-libsoxr --enable- libsrt --enable-libsvtav1 --enable-libtwolame --enable-libuavs3d --disable-libdrm --disable-vaapi --enable-libvidstab --enable-vulkan --enable-libshaderc --enable-libplacebo --enable-libx264 --enable-libx265 --enable-libxavs2 --enable-libxvid --enable-libzimg --enable-libzvbi --extra-cflags=-DLIBTWOLAME_STATIC --extra-cxxflags= --extra- ldflags=-pthread --extra-ldexeflags= --extra-libs=-lgomp --extra- version=20220613 libavutil 57. 26.100 / 57. 26.100 libavcodec 59. 33.100 / 59. 33.100 libavformat 59. 24.100 / 59. 24.100 libavdevice 59. 6.100 / 59. 6.100 libavfilter 8. 40.100 / 8. 40.100 libswscale 6. 6.100 / 6. 6.100 libswresample 4. 6.100 / 4. 6.100 libpostproc 56. 5.100 / 56. 5.100 Input #0, h264, from 'example.h264': Duration: N/A, bitrate: N/A Stream #0:0: Video: h264 (Main), yuv420p(tv, bt709, progressive), 1280x720 [SAR 1:1 DAR 16:9], 29.97 fps, 29.97 tbr, 1200k tbn Stream mapping: Stream #0:0 -> #0:0 (h264 (native) -> wrapped_avframe (native)) Press [q] to stop, [?] for help Output #0, null, to 'NUL': Metadata: encoder : Lavf59.24.100 Stream #0:0: Video: wrapped_avframe, yuv420p(tv, bt709, progressive), 1280x720 [SAR 1:1 DAR 16:9], q=2-31, 200 kb/s, 29.97 fps, 29.97 tbn Metadata: encoder : Lavc59.33.100 wrapped_avframe frame= 1082 fps=912 q=-0.0 Lsize=N/A time=00:00:36.10 bitrate=N/A speed=30.4x video:499kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown [Parsed_vfrdet_0 @ 000001a582b7f900] VFR:0.799260 (864/217) min: 40040 max: 40041 avg: 40040 }}} What it should be as if -r 29.97002997 was before input. In fact Mediainfo can see all of it (both the timetamps of mp4 and time_scale / num_units_in_tick) in -c copy to mp4 with -r 29.97002997 and without. There were quite a lot of simliar bugs in that regard, but Annex B to mp4 is a clear case and is a clear bug. Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker. -- Ticket URL: <https://trac.ffmpeg.org/ticket/9814> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#8515: vc1_parser erroneously flagged every packet as keyframe -------------------------------------+------------------------------------- Reporter: HolyWu | Type: defect Status: new | Priority: normal Component: avcodec | Version: git- | master Keywords: vc-1 parser | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Since the commit of https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/701e8b42e12ad625c64ceae2252…, vc-1 parser erroneously flagged every packet as keyframe. If you recompile the tool with that commit reverted, you will get the expected result. The first shows the result with that commit. The second shows the result without that commit. {{{ $ ffprobe -pretty -show_packets vc1_sample.mkv [PACKET] codec_type=video stream_index=0 pts=N/A pts_time=N/A dts=959 dts_time=0:00:00.959000

For example, "ffmpeg -h encoder=libfdk_aac" shows the arg "-vbr <int> VBR mode (1-5)" However "ffmpeg -h encoder=aac_at" shows no such argument for VBR AAC using AAC_AT (it's not only "-h" page missing, "-vbr <int> doesn't work") Moreover, files currently produced with "-c:a aac_at -aac_at_mode 3" produce CBR instead of VBR. So simple AAC_AT completely lacks modes 2 (VBR + Cap) and 3 (VBR) -- Ticket URL: <https://trac.ffmpeg.org/ticket/9727> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#4591: attachments mjpeg are discovered wrongly as video stream and therefore h264 encoding is broken -------------------------------------+------------------------------------- Reporter: TheoMeister | Type: defect Status: new | Priority: important Component: avformat | Version: Keywords: attachments | Blocked By: video | Reproduced by developer: 0 Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: Encoding with libx264 broken since https://github.com/FFmpeg/FFmpeg/commit/511585ce7f7272e5069ef011d6be5f073d2… - reverting this patch makes it working again as before as the attachments are just copied and not h264 encoded (which is not desired).
