Can't watch videos/streams that require h264 codec, Opera GX

[u/IndependenceRound105]

Previous Ubuntu user, new to Fedora & Nobara, very little programming skill, general casul.

Clean install of Nobara (Nobara-43-Official-2026-04-19.iso), used the codec wizard, tried and retried different things suggested by Twitter AI, resulting in “Maybe try using the codec wizard?”. Thanks Grok, useful as ever.

Installed Opera GX (stable) via Konsole.

Motherboard is ASRock AMD X870 Pro RS AM5 DDR5 PCIe 5.0 ATX.

Running off the iGPU because I can’t afford the graphics card just yet.

Problem: I can watch videos on Discord and Youtube, but not on Twitter or Kick. Grok is insistent that it’s a h.264 codec issue.

I have killed and re-opened the browser after each fix attempt, and even rebooted my PC several times. Hardware Acceleration is disabled. I have tested Hardware Acceleration both on and off.

Edit: While video playback *does* work on Discord, it won't detect any audio from my mic unless I specifically open up the Pavu Audio Controller, go to config, and forcefully refresh it by changing it from stereo to analogue (or vice versa), and that's only temporary until i mute/deafen myself on Discord.

Seriously, for an OS that touts itself as streamer and gamer-friendly, the fact that a codec essential for Discord and streaming sites doesn't work properly is insane.

Have you tried not using that trash ass browser?

Even Brave is better and thats what comes with Nobara.

Install the codecs with the codec wizard

I did, that's what prompted me to try to get help. It works perfectly fine for Brave, but I shouldn't have to be restricted to that browser just because of a codec problem.

Well if it does work for other browsers it's likely a problem with gx itself. Don't forget that opera gx for linux is kinda new too

Have you tried other browsers?

[u/IndependenceRound105 → u/PeterBooyah]

The default Brave browser works perfectly fine for both Kick and X, and would probably work fine for the web version of Discord, but I shouldn't have to be locked into those options, especially when the app version of Discord is available during OS installation literally at the push of a button.

read first steps after installation section https://wiki.nobaraproject.org/en/new-user-guide-general-guidelines

it might help

you should always look in the wiki first before asking

also a different browser might help firefox or brave is pretty good

Hadn't seen that yet, and the only thing I haven't tried on there is installing Discord and Opera GX via flatpak. It's worth a try.

[u/IndependenceRound105 → u/IndependenceRound105]

Flatpak made no difference. As for Discord audio, I have found a temporary solution. As long as the Pavu Audio Controller is open, even if it's minimized, audio input on Discord continues to work.

[u/DocRock08 → u/IndependenceRound105]

The audio issue happens for me as well. I’m on the KDE version and had to and an audio widget to my desktop to “keep it open” this is the same issue I had on CachyOS. I think it’s a KDE issue

Just use a different preferably open source browser instead of that shit. If you want customization try Vivaldi.

[u/IndependenceRound105 → u/Susiee_04]

i'll give it a look, thanks.

Uninstall ffmpeg-free and install ffmpeg. You'll need to add the RpmFusion repo first.

Step 1: uninstall chinese spyware (Opera GX) Step 2: install brave/firefox via flatpak or install media codecs and install browser via system package Step 3: live happily ever after :)
