I recently screen recorded my first Ubuntu video. I saved it to my desktop and when I play it, it works fine.

But when I copy the video (mp4 format) to my local disk c drive and reboot it to windows to play it. It gives me an error "Bad file descriptor"

How do I export my Ubuntu screen recorded files to windows.

  • You have to recode using avconv from libav-tools, avconv -i MyMovie.mp4 -vcodec libx264 -preset veryfast -pix_fmt yuv420p -acodec libmp3lame -ar 44100 -ab 64k -threads 4 -y MyMovieForWindows.mp4. Not all options are needed the "pix_fmt yuv420p" is essential I think.

While MP4 can contain many different codecs, Kazam's codecs are quite straight forward. It's h.264.

This is a fairly universal codec these days but I wouldn't be surprised if you still needed to download a decoder codec for Windows.
