[SOLVED] Wayland, mplayer system freeze

I'm not sure this is the correct place to post this since I'm not sure what the issue is.

The system
Using a thinkpad laptop with an integrated video system and a nvidia card as well. Using nvidia drivers.

The issue
When I try to play a video with mplayer, the system freezes. Can't move the mouse, open anything, use anything that is open, change to another tty or anything. I have to hard reset the system.

I put "Wayland" in the title because mplayer can play the video if I switch to X11.

Here's what I tried before switching to X11:
- Had some mplayer error messages about sound so I added my user to the audio group
- Had some journalctl error messages about i2c access so I added my user to the i2c group
- Reinstalling the nvidia drivers (nouveau is not installed)
- Using prime-run to run mplayer
- Editing the plasma-powerdevil.service, adding

[Service]
Environment=POWERDEVIL_NO_DDCUTIL=1

Last lines of log from journalctl before the crash

Jun 04 19:43:23 thinkpad-p1 systemd[1]: Started dbus-:1.3-org.kde.powerdevil.backlighthelper@1.service.
Jun 04 19:43:33 thinkpad-p1 systemd[1]: dbus-:1.3-org.kde.powerdevil.backlighthelper@1.service: Deactivated successfully.
Jun 04 19:43:42 thinkpad-p1 kernel: nvidia-modeset: WARNING: GPU:0: Correcting number of heads for current head configuration (0x00)
Jun 04 19:43:42 thinkpad-p1 kwin_wayland[924]: kf.windowsystem: static bool KX11Extras::mapViewport() may only be used on X11
Jun 04 19:43:50 thinkpad-p1 systemd-logind[740]: Power key pressed short.

I don't know if I should report this as a bug and, if so, where. I don´t know if this is a X11/Wayland problem, powerdevil problem or something else. I decided to post it here and maybe someone can point me in the right direction.

To whoever finds this while searching
Switching to X11 seems to fix everything.

Re: [SOLVED] Wayland, mplayer system freeze

Reinstalling the nvidia drivers (nouveau is not installed)

nouveau is part of the kernel, xf86-video-nouveau us irrelevant on wayland and possibly doesn't even support your GPU on X11

Using prime-run to run mplayer

mplayer freezes the system regardless of prime-run?

glxinfo -B
prime-run glxinfo -B
qdbus6 org.kde.KWin /KWin supportInformation

Does mpv also freeze the system?
How does mplayer perform on weston (reference wayland compositor, it's mostly to test "not-kde" you can also try sway or hyprland)?

I'm not sure what the issue is.

Makes the newbie corner a fine pick smile

Switching to X11 seems to fix everything.

I'm inclined to turn that into a wallpaper cool

I'll get on testing these, might take a while. I'll update as they come along.

UPDATE
mpv works fine, mplayer still crashes the system.

Weston, when called from inside Plasma (Wayland), crashes the whole system, had to hard reset.

Weston by itself doesn't crash the system but also doesn't play the video. Some messages about the video's audio, some message about codecs (I still can play the video under X11).

Hyprland doesn't crash the system but also doesn't play the video, just gives me a black screen that won't play the video. If I CTRL+C the terminal I used to call mplayer, the window doesn't close either, just stays there, blank.

Re: [SOLVED] Wayland, mplayer system freeze

The outputs you posted were apparently drawn on an X11 session - that's pointless.

Weston, when called from inside Plasma (Wayland)

Yeah, no - the point was to not use plasma at all.

Weston by itself doesn't crash the system but also doesn't play the video. Hyprland doesn't crash the system but also doesn't play the video

Can you run xterm on plasma/wayland?
Do you have a custom mplayer config, https://wiki.archlinux.org/title/MPlayer#Configuration ?
(I suspect it's trying to output on an X11-specific backend)

Re: [SOLVED] Wayland, mplayer system freeze

Sorry, didn't even think of that.

"Unfortunately" the output is effectively the same (and unsuspicious)

Yes

So it's not xwayland per se.
Nevertheless, looking at the -vo modules provided by mplayer, there's nothing that would not depend on X11 so you'll likely be getting an xwayland client (you can check on hyprland/weston whether that's the case)
Does "mplayer -vo sdl video.mp4" work?

Re: [SOLVED] Wayland, mplayer system freeze

I double checked the outputs from wayland and x11 after you mentioned they're similar and it's right, they're very similar.

mplayer -vo sdl video.mp4

Works (as in no crash) but only for audio, I don´t get an image/video.

Re: [SOLVED] Wayland, mplayer system freeze

So equivalent to /dev/null

SDL_VIDEODRIVER=wayland mplayer -vo sdl video.mp4 # video or rather crash?
mplayer -vo gl video.mp4 # this will probably only work via xwayland
mplayer -vo xv video.mp4 # this will for sure and is probably the crashing one

Sanity check: since mplayer doesn't seem to have any native wayland support nor be in frequent development, did you consider to just switch to mpv if you want to use wayland instead of X11?

Re: [SOLVED] Wayland, mplayer system freeze

SDL_VIDEODRIVER=wayland mplayer -vo sdl video.mp4

No crash and no video output

mplayer -vo gl video.mp4

Works with video under Wayland

mplayer -vo xv video.mp4

Works with video under Wayland

I don't mind the video player. I just used mplayer because it's what I used in the past. Muscle memory I guess. I also thought it was a problem with something else and not with mplayer. But sure, if mplayer is no longer under active development, I'm fine switching to something else. Just didn´t know that was the case.

'key

2. what output did you use by default otherwise?

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

I just used "mplayer" without any arguments other than the video. Is there any command I should use to get the default vo or the above output is enough to find it out? This was under X11 since I didn't want to crash again.

Re: [SOLVED] Wayland, mplayer system freeze

It'll default to vdpau unconditionally - I don't think that mplayer has any wayland gateway.
If you're feeling adventurous, does "vdpauinfo" fail on sway/hyprland and/or crash kwin_wayland?

UPDATE
This is under Hyprland, the command didn't crash it but when I tried to exit it, it frooze. Had to restard sddm and save the output to a file. It (hyprland) also seems to have erased my browser cache: had to relog into email and this forum.
