Next, run the ffmpeg command: {{{#!bash ./ffmpeg_g -y -v 9 -loglevel 99 -i small_movie.mp4 -pass 2 small_movie_out.mp4 }}} Options `-v 9 -loglevel 99` are optional and were only added to produce verbose logs. ==== Console output: {{{ ffmpeg version N-113344-gbe4fcf027b Copyright (c) 2000-2024 the FFmpeg developers built with gcc 11 (Ubuntu 11.4.0-1ubuntu1~22.04) configuration: --disable-asm --toolchain=gcc-asan --disable-ffplay --disable-ffprobe libavutil 58. 36.101 / 58. 36.101 libavcodec 60. 37.100 / 60. 37.100 libavformat 60. 20.100 / 60. 20.100 libavdevice 60. 4.100 / 60. 4.100 libavfilter 9. 17.100 / 9. 17.100 libswscale 7. 6.100 / 7. 6.100 libswresample 4. 13.100 / 4. 13.100 Splitting the commandline.

#10843(ffmpeg:new): A -shortest-video option that acts just like -shortest but ignores audio

#10843: A -shortest-video option that acts just like -shortest but ignores audio -------------------------------------+------------------------------------- Reporter: Florian | Type: | enhancement Status: new | Priority: minor Component: ffmpeg | Version: Keywords: shortest, | unspecified duration, -t | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Anyone who exported a final project with video+audio ready to then encode with ffmpeg, they don't want the audio to extend the last frame of video. Yet they cannot use **-shortest** because this would make the audio trim the video if shorter. A good solution to that problem would be a **-shortest-video** option which would act exactly like **-shortest** but would only look at the video inputs. Also, this is probalby extremely simple to implement since you already have -shortest Thanks! -- Ticket URL: <https://trac.ffmpeg.org/ticket/10843> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#8948(undetermined:new): CUDA decoder fails on certain files.

#8948: CUDA decoder fails on certain files. -------------------------------------+------------------------------------- Reporter: ericbg | Type: defect Status: new | Priority: normal Component: | Version: git- undetermined | master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: When I try to use a CUDA decoder on a specific file, I end up getting an error "Using more than 32 (42) decode surfaces might cause nvdec to fail." and then it won't use CUDA to process the file.. The number in the brackets seems to be "29 + threads"; for example, I have a 12-thread Ryzen 3600 and when I don't specify threads it says 42 (for some reason internally 'threads' is set to 13 even though I don't have that many?), when I try `-threads 4` it says 33, and when I try `-threads 3` it just works! This is where the error is from: https://github.com/FFmpeg/FFmpeg/blob/master/libavcodec/nvdec.c#L401. The problem is also file-specific; after I re-enc the file, it works just fine without any fiddling. Computer: Ryzen 3600, Nvidia 1660Ti, Windows 10 Pro N.

#6763(swscale:new): swscale: Out-of-bounds memory accesses
by FFmpeg 13 Apr '25

13 Apr '25

#6763: swscale: Out-of-bounds memory accesses ---------------------------------+--------------------------------------- Reporter: Gramner | Type: defect Status: new | Priority: normal Component: swscale | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ---------------------------------+--------------------------------------- Many assembly functions in swscale will read past the end of their input buffers which causes segfaults and/or bus errors if the buffer happens to be located near the end of a memory page and the next page is invalid. Aligning input buffers isn't even enough for formats like RGB24 (and requiring alignment would be a bad idea anyway since it wouldn't work with memory-mapped input files for example). Using swscale with x264 CLI seems to be a fairly consistent way to trigger such out-of-bounds crashes. This command line for example will cause segfaults in ff_rgb24ToY_avx(): ./x264 -o /dev/null --input-csp rgb --input-res 512x512 <any_input_file> If asm is disabled in swscale the problem goes away. -- Ticket URL: <https://trac.ffmpeg.org/ticket/6763> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#8343(avcodec:new): h261dec doesn't mark keyframes
by FFmpeg 12 Apr '25

12 Apr '25

#8343: h261dec doesn't mark keyframes ----------------------------------+---------------------------------- Reporter: Lastique | Type: defect Status: new | Priority: normal Component: avcodec | Version: 4.2 Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+---------------------------------- h261dec does not set AVFrame::key_frame field on keyframes. As a side effect, frame skipping except keyframes doesn't work (all frames are skipped). In H.261, keyframes are normally indicated by the Freeze Picture Release bit in the Picture Header of a frame, but h261dec ignores that bit. h261enc behavior is to set that bit on keyframes. The problem was discovered in a client application that uses ffmpeg through its C API. I'm not sure if it can be reproduced through command line. Attached is a patch that fixes the problem. The patch has been posted on ffmpeg-devel: https://lists.ffmpeg.org/pipermail/ffmpeg-devel/2019-October/252145.html -- Ticket URL: <https://trac.ffmpeg.org/ticket/8343> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

It should probably also be changed to mux WebVTT tracks as S_TEXT/WEBVTT, at least to Matroska so mkvtoolnix recognizes the track as valid subtitles. {{{ ffmpeg -i cut-vtt.mkv ffmpeg version N-80317-gff53b66-g9da27fb+1 Copyright (c) 2000-2016 the FFmpeg developers built with gcc 5.4.0 (Rev1, Built by MSYS2 project) configuration: --enable-libx264 --enable-libvpx --enable-libopus --disable-postproc --disable-doc --disable-demuxer=asf --disable-ffplay --enable-gpl --disable-debug libavutil 55. 24.100 / 55. 24.100 libavcodec 57. 46.100 / 57. 46.100 libavformat 57. 38.100 / 57. 38.100 libavdevice 57. 0.101 / 57. 0.101 libavfilter 6. 46.101 / 6. 46.101 libswscale 4. 1.100 / 4. 1.100 libswresample 2. 1.100 / 2. 1.100 [matroska,webm @ 000000038f2d1c60] Unknown/unsupported AVCodecID S_TEXT/WEBVTT.

#6949(undetermined:new): No support for multiple values in ID3v2.4 tags.

#6949: No support for multiple values in ID3v2.4 tags. -------------------------------------+------------------------------------- Reporter: | Type: defect escapereality | Priority: normal Status: new | Version: Component: | unspecified undetermined | Blocked By: Keywords: ID3 FFprobe | Reproduced by developer: 0 libavformat | Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- Altough ''FFmpeg'' states that it has support for ID3v2.4 tags, there is one thing I can't get to work properly. The [http://id3.org/id3v2.4.0-frames ID3v2.4 specifications] state the following: ''There may only be one text information frame of its kind in an tag. All text information frames supports multiple strings, stored as a null separated list, where null is represented by the termination code for the character encoding.'' When I separate the values in a tag with NULL-characters, the values should all be recognized (following the ID3v2.4 specs). However, when I use ''FFprobe'', it only shows the first value. For example [http://mutagen.readthedocs.io/en/latest/man/mid3v2.html mid3v2] shows the tags correctly. [[BR]] Below is (a snippet of) the output of both ''mid3v2'' and ''FFprobe'' with an example file. The '''TCON''' (genre) and '''TPE1''' (artist) contain multiple values.
