Video playback problems with intel graphics [solved]

General system Multimedia
1

Hi,

Freshly installed i3 and xfce on a Dell XPS 9315 (intel graphics). I get sound from videos, but no moving pictures.

Running mpv from the shell shows no errors. With vlc I get the following output:

LC media player 3.0.18 Vetinari (revision 3.0.13-8-g41878ff4f2)

Any suggestions?

I have installed libva-intel-driver, rebooted and now get:

It looks like it is not finding a lib file still, if you install libvdpau-va-gl that should provide it for you.

Also, there is a newer driver now, which may or may not work better for you

Pulled from optional dependancies of libva

Thanks for helping out.

I installed libvdpau-va-gl and intel-media-driver and rebooted and still no luck. libva-intel-driver was already installed.

When running VLC from the command line I get no errors, but the image still does not move. When quitting VLC I get (opening an mp4 file):

VLC media player 3.0.18 Vetinari (revision 3.0.13-8-g41878ff4f2)

With mpv I see no errors in the console, but still no moving pictures.

It always worked perfectly until recently :frowning:

Interestingly, video playback works fine when running directly from the installation medium in xfce (I use i3).

Oh! Knowing it had worked until recently triggered a thought. By recently, would that be today? The libplacebo pkg was updated today.

yay -Qi libplacebo

From the last error, it looks like you have v5.229.2, so you could try to downgrade it to the previous.

sudo downgrade libplacebo

If this works, you may want to report the error upstream at https://github.com/haasn/libplacebo

At the moment, that seems like it would support the theory that downgrading the libplacebo library will help. There are still other factors at play between the ISO and bare metal, so that might only be wishful thinking.

Edit:
I also use i3, but on a HP Omen Optimus laptop. I did find an mp4 in my library, and it plays in mpv on my system. As I am using nvidia, this doesn’t really provide much help as to whether it is libplacebo, or still hunting a missing lib or config, unfortunately.

I downgraded to 5.229.1-1 without luck. Going down to version 4 breaks an mpv dependency.

What analysis can I do to compare the live ISO with the installed version?

10

I removed the xf86-video-intel driver, according to this page.

I also installed the same packages as in the live distro. VLC still gives some errors, but plays videos.

Sorry, had to run a couple of errands.

Sounds like you figured out how to compare and find the differences for ISO and installed files.

Glad to hear you got it working. Not sure why it would have stopped working for you, but you might take a look at Arch Wiki Intel, to see if you can get direction for any of the remaining errors.

Thanks. That looks very technical. It works so I stick with what I have now. I am sure any issues will fix themselves in future updates. I don’t know enough about hardware to properly troubleshoot this issue.

Postscriptum: I did a fresh install, removed xf86-video-intel, rebooted and presto.
