Bug 1440331

Created attachment 1269956 [details]
enable 3rd party screenshot

This pop-up says it's provided by "fedora" which isn't 3rd party to me, so in retrospect this dialog seems specious.

It does not work on my Fedora26 when I try to play mp4 files. There are several dup bugs against this plugin.
It impacts user's experience in multimedia using Fedora. So, could you evaluate this problem and assign it to the right component if needed?

I found a workaround in below link, which, at least, makes my player works on my Fedora26.
Just need to follow the step1~step3.

Still not fixed in Fedora 27.

On Fedora 27, it is now possible to click on the "Enable and Install" button. However, clicking the button displays a "repo already enabled" error message and installation is aborted.

More information from Christophe Fergeau (https://bugzilla.gnome.org/show_bug.cgi?id=786038#c1):

Happens to me on f26 as well as with gnome-software master. With gnome-software master, this gives an error that the repository was already enabled.
The code goes up to gs_plugin_app_install() in gs-plugin-packagekit.c, GsApp::state is AS_APP_STATE_UNAVAILABLE so it tries to enable the repo, but for some reason it's already enabled, so an error is returned, which makes gnome-software stop the installation.

This is affecting me on F27 too. Suddenly, mp4 playback doesn't work, when I open a video in the Videos application I'm shown the message "H.264 (High Profile) decoder is required to play the file, but is not installed".

Below that is a "Find in Software" button, but clicking through and trying to install the codec results in the same problem above, where installation fails because the repo is supposedly already enabled.

Thus, video playback is utterly hosed on this system.

I've tracked this down to a bug in setting "origin" in gnome-software, fixing it now.

Should be fixed in https://gitlab.gnome.org/GNOME/gnome-software/commit/8c87d39351c976873c791e39732763f85b86660f

Kalev, can you please backport the same fix for F26?

No, sorry, this change is particularly invasive and can break a lot of unrelated things.

I added the rpmfusion repo and the gstreamer package installed because that was the external repo it was trying to add.

Can you open a new bug with a detailed description what's going wrong, and how to reproduce it, please? The original issue here should be fixed.

After doing these steps, it works.

sudo dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm
sudo dnf install gstreamer1-libav
