Some users, particularly on seedboxes, may have an outdated/limited ffmpeg installed that will not function correctly with UA.

One method to check is below:

`which ffmpeg` -v quiet -hide_banner -version | grep -q -- --enable-libzimg && echo "FFmpeg compiled with libzimg" || echo "FFmpeg not compiled with libzimg"

Since UA version 5.2.0, you can now provide a static binary for UA to use. Create a folder named ffmpeg within the UA bin directory: https://github.com/Audionut/Upload-Assistant/tree/master/bin

And place the ffmpeg binary ffmpeg within this folder.

The following repos have been suggested as suitable ffmpeg binaries:

https://github.com/BtbN/FFmpeg-Builds/releases/tag/latest // Some issues have been reported with these builds.

https://github.com/eugeneware/ffmpeg-static

For Windows, the author uses: https://github.com/BtbN/FFmpeg-Builds/releases/tag/autobuild-2025-08-31-13-00 The ffmpeg-n7.1.1-57-g1b48158a23 type.

There were issues in builds after this date, they may have been resolved since last checked.

Another way to do this is adding to the start of PATH environment variable the extracted ffmpeg<version>/bin path from the release bundles linked above and UA will use that instead.

Example, in my own environment, added this line in ~/.profile

export PATH="/home/ppkhoa/ffmpeg-master-latest-linux64-gpl/bin:$PATH"

Continued issue may be resolved by setting use_libplacebo to False in config https://github.com/Audionut/Upload-Assistant/blob/b7aea987b147e903115e46121675b91549ad017c/data/example_config.py#L82
