Installing ffmpeg

FFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. It supports the most obscure ancient formats up to the cutting edge.

Videos uploaded to YouTube or other platforms are often stored on the server in separate files, one file for the video track and one for the audio track. To merge these two files, the Moodle downloader needs ffmpeg.

On Linux ffmpeg can be easily installed using the package manager.
