I’m trying to install Chromium on Rawhide,but dnf is displaying nothing provides libopenh264.so.7 which is required by Chromium.
The Fedpra Packages web site shows the noopenh264 package includes this particular library and the package is installed, yet dnf continues to display the above.
But in /usr/lib64, there is a symlink for libopenh264.so.8 pointing to libopenh264.so.2.6.0.
Would this require an updated Chromium version, that is not yet available for Rawhide?
Thank you in advance.
Just a couple comments.
First, rawhide is the development version of fedora that is constantly changing and is never recommended for users that may expect stability. Some things break regularly in rawhide.
Second, expecting user apps such as chromium to keep up with the fast paced changes of rawhide is sadly expecting something that is impossible.
I would strongly suggest that instead of using rawhide where you seem to expect everything to just work you should fall back to the currently stable release of fedora 41, or at worst fall back to fedora 42 that is almost ready for BETA release (it is not yet ready for full release, but is much more stable than rawhide will ever be)
I also run Rawhide. I see the exact issues with libopenh264 that you report if you try to install it from the Fedora rpm repositories. However, you can easily install Chromium from Flathub (I did it as a test case and Chromium was installed without a problem). This is actually a good use of a Flatpak when otherwise package dependencies get in your way.
I would not discourage you from using Rawhide at all. In my experience it provides a great user experience. But you will face these library mis-timings occasionally (especially it seems with openh264 
).
There’s a major OpenH264 update, and Chromium hasn’t been rebuilt yet.
I’ve also been using Rawhide for years and have rarely had any problems.
Since I already have Chromium installed (134.0.6998.88-3), I’m not having any issue because dnf is refusing the OpenH264 update due to missing dependencies.
Now I’m rebuilding Chromium because I don’t know when the update will be available.
The build has started.
We’ll have an update soon.
