Hello,

first i want to say im relatively new to linux and even newer to fedora… i think im quiet a noob so dont be too hard to me :sweat_smile:

when i try to play a twitch livestrem in firefox im getting this Error:
Your browser encountered an error while decoding the video. (Error #3000)

when i look in the console i see this error:
Player stopping playback - error Decode:4 (ErrorInvalidData code 3 - NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - mozilla::MediaResult mozilla::FFmpegDataDecoder<59>::InitDecoder(): Couldn’t open avcodec)

i have installed the rpm fusion repository and already installed alot of varietys of the different ffmpeg versions in dnfdragore.
i also installed vlc.
i also tried different firefox profiles (also default) so its not a setting i changed for hardening.
i also searched for avcodec in dnfdragora and installed them.

nothing of that worked, i hope someone can help and thanks in advance!

I think, but someone should correct me, that if you use the Flatpak version, you can install whatever codec you want on the system, but they will not be used by flatpak version of Firefox since it uses the ones bundled in the flatpak itself (or by using a runtime extension [1]). So, probably, the “issue” lives in the flatpak package.

Well. Which package are you using? [2]
If it is the Fedora Flatpak one, it is likely that some codecs are not included (due to licences and patent issues). On the other hand, Mozilla Flatpak (installed from Flathub) is supposed to include various codecs, and as far as I understand, Twitch should work.

  1. Available Runtimes — Flatpak documentation ↩︎

  2. for instance, open the terminal and issue this command flatpak list | grep Firefox ↩︎

i installed firefox using the pre installed “app store” and in the top right i chose

Fedora Linux (Flatpak)
URL: registry.fedoraproject.org
Installation: system
Branch: stable

when i issue your command i get this output:

Firefox	org.mozilla.Firefox	100.0	stable	fedora	system

Yep. This is the point. As I’ve briefly exposed in the previous post.

I think that you have two options.

  • Install the flatpak version of Firefox from Flathub: Firefox | Flathub

  • Install Firefox from the Fedora Linux RPM repository. In addition you have to install the third party RPM Fusion repository and all the multimedia codecs. But as far as I can understand from your first post, you already installed such things.

Alright thank you very much!
i just installed the Flathub version and it works.
Can i somehow implement the Flathub versions in the “Appstore” or do i always have to use their website?
