Can't find or install missing codex for Parole

I’m trying to listen to .mp4 files I’ve downloaded from Youtube on Parole, but it keeps telling me that it can’t locate the H.264 codec needed to play them. It also offers to install it for me but fails. using dnf provides H.264 doesn’t find anything and leaving the dot out doesn’t help. However, Audacity not only plays the files but exports them as .mp3 as needed for my car’s radio. Does anybody know where to find what I need?

There are a few options, but you’ll likely want to enable RPMFusion. From there you can install vlc, which is capable on its own of playing h264, but ffmpeg and gstreamer are also common backends used by other media players.


And what makes you think I didn’t install and enable all of the rpmfusion repos when I installed Fedora? However, I’ve installed vlc and can play .mp4s now.

Hey, nobody here is fortuneteller! As long as you not mention it, we will propose even if you are a Q&A Leader. Just saying thanks and maybe give a like would save you the initial sentence.
Be kind be friendly :wink:
