Videos grayed out, cannot play (Debian 12 KDE )

vishv

Can't play the video on https://help.vivaldi.com/desktop/media/html5-proprietary-media-on-linux/ . Works fine with chrome on the same computer. Vivaldi used to work on the same computer, albeit with manjaro OS.

OS: Debian 12, KDE on x11.

If you are on the Snapshot, read also the Announcements, they shows info and the replies have found bugs too.

@Zalex108 I'm not on snapshot. I had downloaded and installed some file named vivaldi-stable_6.5.3206.61-1_amd64.deb . Anyway, inserting the ffmpeg file and restarting did not help.

Then follow the firsts steps

@Zalex108 But what steps? Problem persists with incognito window, where no extensions are active.

@vishv You do not need the libffmpeg file; after install the 6.5 Stable with deb packag from https://downloads.vivaldi.com/stable/vivaldi-stable_6.5.3206.61-1_amd64.deb all works nice on Debian 12 KDE. The installer fetches its own correct libffmpeg.
I tested this and all works on my Debian 12.

You can try it with theses commands in shell:

sudo apt purge vivaldi-stable
wget https://downloads.vivaldi.com/stable/vivaldi-stable_6.5.3206.61-1_amd64.deb
sudo dpkg -i vivaldi-stable_6.5.3206.61-1_amd64.deb
sudo apt -f install

@Zalex108 But what steps? Problem persists with incognito window, where no extensions are active.

Mostly,
Point 3, Clean Profile.

But follow @DoctorG before, if persist, then the Point 3.

vishv

@DoctorG - Yes, that's how I installed. I later tried and removed flatpak version as well (no use).

Point 3, Clean Profile.

I already tried with incognito window - so we're covered there.

@vishv Have you checked https://wiki.debian.org/NvidiaGraphicsDrivers#GPU_isn.27t_functional.2C_even_with_a_compatible_driver_version_installed

vishv

Driver is installed -

$ lspci -nnk | egrep -i --color 'vga|3d|2d' -A3 | grep 'in use'
        Kernel driver in use: nvidia

Also chrome seems to display videos at https://help.vivaldi.com/desktop/media/html5-proprietary-media-on-linux/ fine.
