Videos play on my desktop but not on my notebook. The Proton log on my notebook indicates a missing GStreamer plugin, despite having all the necessary plugins (good, ugly, bad, base, etc.) installed.

Both devices run clean installations of Pop_OS! 22.04 LTS with installed GStreamer plugins. The sole difference is that I copied the .steam folder from another Pop_OS! installation to my desktop.

I've tested this across various Proton versions, including Proton Experimental, 8, and 7. All versions exhibit the same problem, videos failing to execute properly, even though they play flawlessly on my desktop.

I'm looking to resolve this issue, whether it's on my end or within Proton. I'm not inclined to install Windows solely for playing this game.

Hello @rafaelhipercg, what game are you showing in your screenshot?

The codecs installed on your host system are not used with Proton. Instead, the Steam client provides access to the h264 codec, but the game config needs to tell the Steam client that it's needed. There's a manual process mentioned at https://github.com/ValveSoftware/Proton/issues/5196#issuecomment-1502075962.

Thanks, the config issue is a game-specific and we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/5520#issuecomment-1912752665.

steam steam://unlockh264/ It works, thank you very much! Why isn't this in the documentation?

Ddpkirchner 2024-06-09 github

What's the deal with this steam steam://unlockh264/ command? Is that how we must start steam if we want to workaround this issue, or is it a one-time thing, or what?
