Fix MATLAB error "only uncompressed AVI movies can be read on UNIX"

MATLAB on Linux claims to only playback uncompressed AVI files on “UNIX” systems. However, MATLAB on Linux can’t even play all uncompressed AVI filed depending on your particular system configuration with gstreamer. The solution thus far with MATLAB seems to be using Motion JPEG in AVI videos.


apt install ffmpeg

ffmpeg -i input.avi -c:v mjpeg -qscale 1 out.avi


  1. Download test video
  2. convert video to Motion JPEG AVI

    ffmpeg -i input.avi -c:v mjpeg -t 1 -qscale 11 out.avi

The sample AVI file is used under GNU LGPL.
