On Kinoite it will be included as a Flatpak, on the Spin as an RPM.

~~Comps PR:~~ https://pagure.io/fedora-comps/pull-request/844

Edit: Whoops, wrong issue.

I have a prototype for the flatpak, but without a runtime extension or the like for openh264, I'm not sure how useful it will be.

No decision so far. We need to compare functionality / codec support between Dragon Player & Haruna.

I have used both and while not extensively my preference is for Haruna.

Verified on a virtual machine that Haruna can play H264 out of the box.
Dragon instead currently fails (!) with

I don't think auto-installation of codecs works with Plasma Discover at all right now.

mmmh i'm not sure where would Discover be involved at all?

Discover is the frontend for PackageKit. In order for package installation to work with PackageKit, the frontend needs to be able to handle the signal and do something with it.

The failure to install gstreamer1-plugin-openh264 was caused by the request not being able to be handled by Discover.

Eh? Doesn't make sense to me. PackageKit is completely indipendent of Discover.
Requests go from clients to PackageKit through dbus, then PackageKit runs libdnf.

In facts the error would indicate that pk-gstreamer-install fails to find org.freedesktop.PackageKit on the bus

Apparently something is supposed to implement a session version of packagekit implementing org.freedesktop.PackageKit.Modify? Oh well; i don't know.

That's supposed to be Plasma Discover. GNOME Software does it for GNOME.

Update from the meeting:
If Haruna is preinstalled, it won't pull in the weak dependency on openh264 so it wouldn't be able to play h264 video.

This is held off until openh264 can be installed from an initial setup wizard

-- side note, at the moment installing Haruna would also not pull openh264 because it is a weak dependency of libavcodec and that is itself preinstalled as a dependency of Plasma. openh264 needs to be added as an mpv weak dependency.

Note that the openh264 can not be included in any of our images (KDE Spin our Kinoite) by default for licensing reasons: https://fedoraproject.org/wiki/OpenH264

This is why Neal created https://fedoraproject.org/wiki/Changes/AutoFirstBootServices

Adding that as a page in plasma-welcome is indeed a good option.

• openh264 is now installed by default (well, noopenh264 is, which is going to be upgraded to the real thing on the first system update)
• phonon doesn't use gstreamer anymore, which means that Dragon does not prompt to install extra codecs anymore. In facts one without vlc-plugins-ffmpeg it can't play much (https://pagure.io/fedora-kde/SIG/issue/612)

So there's no reason to have Dragon as a default anymore.

Well ok, there is one reason: it can playback from CD drives while i think that Haruna cannot. But Haruna offers such a better experience in everything else that I think it overweighs the value of a CD player.

Fine, let's do this for F43.

We may not be doing this as Dragon was rewritten as a QML app that uses QtMultimedia directly (and thus can use GStreamer again).
