====== Video decoders ======

Avidemux uses built-in decoders for video decoding, mostly from the libavcodec library from FFmpeg. It does not use any external decoders(nbsp)(ndash) for example, it uses built-in FFmpeg MPEG-4 for video encoded with Xvid, there's no option to use external Xvid decoder. External FFmpeg is not used either.

The table below shows which video formats (specifications) Avidemux supports and which decoders (software implementations) it uses for decoding them.
