Fixing Firefox Video Playback in Fedora 37

After upgrading to Fedora 37, I noticed that some videos in Firefox were no longer playing. Instead, the error code 224002 was displayed. I have been using Fedora for years and have never encountered this problem. After some research, it was looking like I should enable the OpenH264 Video Codec in the plugin manager and wait for it to download.

Done and done… Except the codec was not downloading no matter how long I waited. Restarting, deactivating/re-activating the video code was also not helping. Turns out that the fix is to install the mozilla-openh264 package yourself:

sudo dnf install mozilla-openh264

Not a big deal, but could have done without the deceptive messaging, Firefox.
