I understand if this is more of a question for the Firefox forums, but I am encountering issues using Twitch.tv with a fresh Fedora 38 installation. I encountered the same issues on Fedora 37 as well.
I encounter the following error when opening a stream:
Based on a bit of preliminary research, it seems to have something to do with the package (and dependencies) ffmpeg either being misconfigured, disabled, or not installed.
A common solution for this issue seems to be installing the Firefox flatpak (which I can confirm works), but the flatpak version of Firefox does not have things like touchpad gestures enabled by default, and I was unable to configure the flatpak version to mimic the one installed by default.
Any help with configuring Firefox or installing the needed packages is greatly appreciated. Thank you!
We do not know anything about the system.
Please post the output of inxi -Fzxx so we can see what hardware and drivers are in use. This sounds like it may be a video driver or codec issue but we need more info to know.
I have not installed any additional codecs on this machine.
I just attempted to install mozilla-openh264-2.3.1-2.fc38.x86_64, which, by its description, seems to be exactly what I need, but it doesn’t seem to have resolved the issue.
I would suggest that you install
libavcodec-freeworld & ffmpeg as well as libheif-hevc.
This would need to be done in 3 steps. dnf install libheif-hevc dnf swap libavcodec-free libavcodec-freeworld dnf swap ffmpeg-free ffmpeg
It also would require that you install/enable the rpmfusion-free and rpmfusion-nonfree repos as shown here before the above can be done. https://rpmfusion.org/Configuration
This would enable most/all the codecs that are restricted within fedora.
I’m not sure how to check the status of these via command line, but in the Software program, all repos are enabled aside from the test ones (e.g. RPM Fusion for Fedora 38 - Nonfree - Test Updates).
Sorry, that was a typo above and has been fixed.
It was meant to be libheif-hevc and is available from rpmfusion.
I would not suggest having any of the testing repos enabled for long periods unless you intend to always test new packages as soon as they are available and maybe even while bugs exist before they are released.
Use dnf repolist as suggested to see what is enabled on your system.
I’ve followed the instructions provided to install the following packages:
libheif-hevc
compat-ffmpeg4
I receive a broken packages warning when running the following commands:
dnf swap libavcodec-free libavcodec-freeworld

I am digging around in the Firefox UI and have found the following in the Add-ons Manager:
