Watching in Firefox

Hi everyone,

I understand if this is more of a question for the Firefox forums, but I am encountering issues using 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.

Do you have the proprietary codecs installed? Twitch uses H264.

Here is the output of running inxi -Fzxx:

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.

This would enable most/all the codecs that are restricted within fedora.

Thank you for your suggestion. libheic-hevc doesn’t seem to exist in any of the repos I’ve enabled.

Here is the output of ls in /etc/yum/repos.d:

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).

Any additional help would be appreciated.

Current Firefox version still doesn’t support ffmpeg 6.0. You need to install compat-ffmpeg 4.4 from the RPM Fusion repository:

sudo dnf install compat-ffmpeg4

Restart your browser.

You can use dnf repolist to list enabled repos; you can also specify the options --disabled or --all.

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.

Hi everyone,

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
 Problem: problem with installed package libavformat-free-6.0-4.fc38.x86_64
  - package libavformat-free-6.0-2.fc38.x86_64 requires libavcodec-free(x86-64) = 6.0-2.fc38, but none of the providers can be installed
  - package libavformat-free-6.0-4.fc38.x86_64 requires libavcodec-free(x86-64) = 6.0-4.fc38, but none of the providers can be installed
  - conflicting requests
  • dnf swap ffmpeg-free ffmpeg
 Problem: problem with installed package libswscale-free-6.0-4.fc38.x86_64
  - package ffmpeg-libs-6.0-6.fc38.x86_64 conflicts with libswscale-free provided by libswscale-free-6.0-4.fc38.x86_64
  - package ffmpeg-libs-6.0-6.fc38.x86_64 conflicts with libswscale-free provided by libswscale-free-6.0-2.fc38.x86_64
  - package ffmpeg-6.0-6.fc38.x86_64 requires ffmpeg-libs(x86-64) = 6.0-6.fc38, but none of the providers can be installed
  - conflicting requests

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

Despite what the yellow message says, the codec is never installed.

You might try the options --best --allowerasing to that; and the same for the ffmpeg swap.

It seems that with F38 the package libheif-hevc has been replaced by libheif-freeworld which should automatically be done with an upgrade.

Thanks, @computersavvy! This has resolved the issue.

I’ll go ahead and mark your original post as the solution.
