This tutorial is grossly obsolete with regard to ffmpeg API. It uses
img_convert, which has been completely removed more than three years ago and
was already deprecated three years before that. It also uses
avcodec_decode_video, that was also deprecated three years ago.

This is not related to your problem, but you should know that working like
that with the root account is usually a very bad idea. That is also the
reason you need to set the display.
