Many dropped frames playing 4k h264 video with mpv

Hello

Many frames are dropped when mpv plays a 4k h264 video (30 or 60fps) on my Arch.
"intel_gpu_top" command indicates that hardware acceleration is working - its "Video" bar goes up to 40% during playback.
Weirdly mpv-based players Celluloid and SMPlayer do not drop frames, or drop much less than mpv; the same videos are watchable with them.

My system:

Operating System: Arch Linux 
KDE Plasma Version: 6.5.91
KDE Frameworks Version: 6.22.0
Qt Version: 6.11.0
Kernel Version: 6.18.8-arch2-1 (64-bit)
Graphics Platform: Wayland
Processors: 8 × Intel® Core™ i7-4790 CPU @ 3.60GHz
Memory: 32 GiB of RAM (31,2 GiB usable)
Graphics Processor: Intel® HD Graphics 4600

The /etc/mpv/mpv.conf file:

hwdec=auto-safe
vo=gpu-next
#--hwdec=vaapi
#keepaspect=no
save-position-on-quit

Any idea on how to solve the problem with mpv on my system?

Thanks for reading.

Re: Many dropped frames playing 4k h264 video with mpv

What's the output of

mpv -v /path/to/some/4k/porn.mp4

The /etc/mpv/mpv.conf file

Tried vaapi & gpu ?
Any change between

mpv --gpu-context=wayland yeahsure.mp4

and

mpv --gpu-context=waylandvk everybodyknowsitsporn.mp4

Re: Many dropped frames playing 4k h264 video with mpv

vaapi and gpu produce the same result. Your alternatives too.

Is at least one CPU core completely maxed out?
Is this a hybrid graphics system?
Can you try the behavior on kde on X11?

Re: Many dropped frames playing 4k h264 video with mpv

No cpu core is completely maxed out.
This pc only has an intel iGPU.
Tested on X11 right now; much less dropped frames on it.

Still many dropped frames with

mpv --ao=null --hwdec=vaapi --vo=gpu --gpu-context=wayland bbb_sunflower_2160p_60fps_normal.mp4

Re: Many dropped frames playing 4k h264 video with mpv

You should be able to inspect the command lines smplayer (and probably celluloid) build for mpv, also make sure they don't end up just turning it into an xwayland client…

SMPlayer is running on Xwayland, Celluloid runs natively on Wayland.

Re: Many dropped frames playing 4k h264 video with mpv

So actually hardly anything, either it reconfigures it through a socket (though none defined there) or stdin (me) or maybe this is also secrectly X11 (while the hosting GUI isn't)
Does xrestop list mpv or do you get output from xprop or xwininfo?

Re: Many dropped frames playing 4k h264 video with mpv

So smplayer runs on X11, celluloid just runs a regular mpv client (in pseudo-gui mode) on wayland and neither result in frame drops, nor does mpv on X11 but does on wayland… great.
How do any of

mpv --gpu-context=x11
mpv --gpu-context=x11egl
mpv --gpu-context=x11vk

perform?

Re: Many dropped frames playing 4k h264 video with mpv

According to info shown by pressing shift+i, mpv drops frames on X11 too, just less than on Wayland.

shift+i of mpv is still reporting many dropped frames with all your 3 commands; but the video playback is satisfactory with the 2nd and 3rd commands.

Re: Many dropped frames playing 4k h264 video with mpv

Occasional framedrops might be AV sync related.
Does native wayland playback behave nicer on other compositors (weston)?

Are there other differences between the celluloid/normal invocation (fullscreen, window decoration, layer)?

Re: Many dropped frames playing 4k h264 video with mpv

There is no significant difference between Celluloid playing in windowed mode and fullscreen mode on Plasma Wayland.
I have just tried Celluloid and mpv under Weston and gotten the same results; MPV drops ~50 frames per second according to info provided by MPV itself by pressing shift+i.

Do you run into this w/ https://download.blender.org/demo/movie … al.mp4.zip or https://download.blender.org/demo/movie … al.mp4.zip ?
Dropping frames w/o resource limits seems a vblank related issue (esp. since this is only on wayland)

Re: Many dropped frames playing 4k h264 video with mpv

Try to report this behavior on Github. Anyway, a workaround to have the smoothest playback possible on wayland is using `vo=dmabuf-wayland`. But, as the documentation says, it's not the same quality as the standard video output (even if I did not notice a big drop in the quality of the images).

Tried the video from the first link; no dropped frame.

Still dropped frames with "vo=dmabuf-wayland".

Edit:
Sorry. "vo=dmabuf-wayland" does not work at all. MPV no even appears on the screen.

Re: Many dropped frames playing 4k h264 video with mpv

I have a laptop with an integrated AMD VGA and a less powerful CPU than yours and I got no dropped frames on H264 2160p60 videos using `vo=dmabuf-wayland` (the only vo that doesn't drop frames on my system, Gnome Wayland).

Well, one more bizarre problem on my system then. I have a laptop with i5 13420h cpu running another OS with Plasma Wayland (neon unstable, based on ubuntu 24.04) and mpv from flathub plays the same 4k video (with vaapi acceleration) smoothly on it.

It could be an older version of mpv which is making the difference. You have to report this behaviour to mpv devs on https://github.com/mpv-player/mpv/issues

I have also tested mpv from flathub on my Arch; it drops frames too.

Re: Many dropped frames playing 4k h264 video with mpv

I have a laptop with i5 13420h cpu

That's a raptor-lake w/ UHD graphics - several generations advanced to the HD4600/Haswell and when it's not rotting away (you're aware of the raptor lake debacle and have the microcode patches?!) quite some faster.

How does the 4k/30fps video perform?
It's not impossible that decoding + scaling + wayland compositor overhead is ultimately too much for the elderly IGP
Since you're losing 5/6 of the frames you'd not be able to decode and play 4k @30fps either in that case - but the magic question is why this doesn't affect
a) xwayland
b) mpv wrapped by celluloid

Does celluloid allow you to configure mpv aspects (decoder/output)?
