I’m on f36 beta Silverblue
I have some video files
Some of them are .webm
Some of them are .mp4, .3gp
The .webm files have a preview
.m4 and .3go have NO preview
Also I can’t open them as there’s no software able to open them
What should I do in order to play those videos and giving them their previews ?
I’d attach a screenshot of a folder containing video files but the forum software doesn’t want to accept my attachment
We need to install additional plugins/codecs to play proprietary formats. Take a look at this:
(Please use the commands necessary for silverblue to install packages etc., though)
Since you’re running silverblue, you may want to try installing the sushi flatpak from flathub.
flatpak install org.gnome.NautilusPreviewer
It allows you to hit the spacebar and preview things in Nautilus, you may need to add some file system overrides depending on where the files are located. You can also use flatseal to modify flatpak permissions.
VLC, Celluloid, and MPV are also available via flatpak on flathub as well.
Thank you ! 
I get this though
$ rpm-ostree install gstreamer1-plugins-base gstreamer1-plugins-good gstreamer1-plugins-bad gstreamer1-plugin-openh264 gstreamer1-libav --exclude=gstreamer1-plugins-bad-free-devel
error: Opzione --exclude=gstreamer1-plugins-bad-free-devel sconosciuta
“opzione sconosciuta” is the Italian for “unkown option”
So it seems that --exclude=gstreamer1-plugins-bad-free-devel is an unknown option
But I copied that line from the link you provided
Am I missing anyhthing ?
Thanks again
that command is for dnf though, I don’t know if the same options apply to rpm-ostree because I haven’t moved to silverblue/kinonite yet.
The man page here suggests that rpm-ostree install does not have an exclude option:
