Hi,

The version of Firefox 68.9 on Linux CentOS 8.2 has problem playing videos from https://www.udemy.com Testing on macOS and Windows 10 the Udemy Courses are presented fine. I get dark video.

Chosen solution

Due to proprietary reasons and such some packages do not get installed on new Linux installs. Among those is the FFmpeg as it is needed to help fully support HTML5 players on websites.

This page mostly does what the old youtube.com/html5 page is telling you if you support all six things or not. https://www.jeffersonscher.com/sumo/html5-video.html

According to computingforgeeks. com/how-to-install-ffmpeg-on-centos-rhel-8

sudo dnf -y install https://download.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm sudo dnf -y install --nogpgcheck https://download1.rpmfusion.org/free/el/rpmfusion-free-release-8.noarch.rpm sudo dnf -y install --nogpgcheck https://download1.rpmfusion.org/nonfree/el/rpmfusion-nonfree-release-8.noarch.rpm

sudo dnf -y install http://rpmfind.net/linux/epel/7/x86_64/Packages/s/SDL2-2.0.10-1.el7.x86_64.rpm sudo dnf -y install ffmpeg

Until here works! sudo dnf -y install ffmpeg-devel
