    FFmpeg - Frequently Asked Questions

    Here are some frequently asked questions about FFmpeg, along with detailed responses to each:

    Why doesn’t FFmpeg support feature?

    FFmpeg development is driven by the tasks that are important to the individual developers. If a feature is not supported, it is because no one has taken on that task yet. If a feature is important to you, the best way to get it implemented is to undertake the task yourself or sponsor a developer.

    How do I encode a movie to single pictures?

    To convert a movie into single pictures, you can use the following command: “`bash ffmpeg -i movie.mpg movie%d.jpg “` This will convert the input `movie.mpg` into images named `movie1.jpg`, `movie2.jpg`, etc. You can also specify the codec explicitly, for example: “`bash ffmpeg -i movie.mpg -f image2 -c:v mjpeg movie%d.jpg “` Note that there is no “jpeg” codec, so you should use “mjpeg” instead.

    Why do I see a slight quality degradation with multithreaded MPEG* encoding?

    Multithreaded MPEG* encoding requires that the encoded slices be independent. This independence can lead to a small reduction in quality because each thread cannot wait for the previous one to finish. This is not a bug but a logical consequence of the encoding process.

    How can I change the frame rate of a video?

    Some codecs, like MPEG-1/2, only allow a small number of fixed frame rates. To change the frame rate, you need to choose a different codec that supports variable frame rates. You can do this using the `-c:v` command line option. For example: “`bash ffmpeg -i input.mpg -c:v libx264 -r 30 output.mp4 “` This command changes the frame rate to 30 fps using the H.264 codec.

    How do I encode Xvid or DivX video with FFmpeg?

    Both Xvid and DivX (version 4 ) are implementations of the ISO MPEG-4 standard. To encode in these formats, use the following command: “`bash ffmpeg -i input.mpg -c:v mpeg4 output.avi “` If you want a specific fourcc (like ‘xvid’), you can use the `-vtag` option: “`bash ffmpeg -i input.mpg -c:v mpeg4 -vtag xvid output.avi “` This will force the fourcc ‘xvid’ to be stored in the output file.

    Why can I not read this file although the format seems to be supported by FFmpeg?

    Even if FFmpeg can read the container format, it may not support all the codecs within that format. Make sure to check the supported codec list in the FFmpeg documentation. If the codec is not supported, you may need to use a different tool or convert the file to a supported format.

    How can I read from the standard input or write to the standard output?

    To read from the standard input or write to the standard output, use the `-` as the file name. For example: “`bash ffmpeg -i – output.mp4 “` or “`bash ffmpeg -i input.mpg – “` This allows FFmpeg to read from or write to the standard input/output streams.

    Why does FFmpeg not see the subtitles in my VOB file?

    FFmpeg may not automatically detect subtitles in certain file formats. Ensure that the subtitle stream is of the correct type (text-based or image-based) that matches the output format’s default subtitle encoder. If necessary, use the `-map` option to explicitly include the subtitle stream.

    How do I join or concatenate video files?

    To join or concatenate video files, you can use the `concat` demuxer. First, create a text file listing the files to be concatenated: “` file ‘file1.mp4’ file ‘file2.mp4’ file ‘file3.mp4’ “` Then, use the following command: “`bash ffmpeg -f concat -i mylist.txt -c copy output.mp4 “` This will concatenate the listed files into a single output file.

    Why was the `-sameq` option removed? What to use instead?

    The `-sameq` option was removed because it was misleading and did not do what users expected. Instead, you should specify the quality or bitrate explicitly. For example, to set a constant quality, use the `-crf` option: “`bash ffmpeg -i input.mpg -crf 18 output.mp4 “` This sets the quality to a specific value (lower values mean higher quality).

    How do I install FFmpeg on Windows?

    To install FFmpeg on Windows, you can follow these steps: 1. Download FFmpeg: Go to a reliable source like gyan.dev/ffmpeg/builds/ and download the `ffmpeg-release-essentials.7z` file. 2. Verify the download: Use PowerShell to check the integrity of the download by comparing the hash. 3. Extract the archive: Use a file archiver like 7-Zip to extract the contents to a folder (e.g., `C:\FFmpeg`). 4. Add FFmpeg to the system path: Edit the system environment variables to include the path to the `bin` folder (e.g., `C:\FFmpeg\bin`).
