The browser then shows an error message “To play video, you may need to install the required video codecs”.
On Firefox I can play the videos without any issues.
YouTube is running fine.
In an attempt to solve this, I manually installed
gstreamer1-libav-1:1.20.0-1.fc36.x86_64
gstreamer1-plugin-openh264-1.20.0-1.fc36.x86_64
