[SOLVED] Videos on web browsers / electron apps stuttering

On any web browser, if I open up any videos, they play slowly and only around 80 frames actually get to the viewport with none dropped (source is youtube's stats for nerds). Nvidia drivers, Hardware acceleration is on, happens on both xorg and wayland. Audio works fine. OS reinstall did not fix. Waiting about 10 minutes seems to fix the issue. I'm not sure what's causing it.

Re: [SOLVED] Videos on web browsers / electron apps stuttering

Does your gpu provide a AV1 hardware decoder? Can you post the output of lspci -v -mm -k and lsmod?

Re: [SOLVED] Videos on web browsers / electron apps stuttering

Video decoder (on brave) is Dav1dVideoDecoder; chrome://gpu says that Video Decode is hardware accelerated. Brave lags less than Firefox, e.g. buffers for a few seconds then plays fine. On firefox, forcing H264 with enhanced-h264ify does not help.

Re: [SOLVED] Videos on web browsers / electron apps stuttering

Acccording to https://en.wikipedia.org/wiki/Nvidia_NVDEC you gpu does not provide a AV1 decoder.

Can you verify that hardware decoding works with GStreamer/VLC/MPV or the backend of your choice by playing an H.264-encoded video locally, for example?

You can get samples at: https://test-videos.co.uk/bigbuckbunny/mp4-h264

Could you please provide the output of :

sudo dmesg | grep nvidia

After a reboot and once you notice the mentioned changes?

Re: [SOLVED] Videos on web browsers / electron apps stuttering

AV1 and AVC1 are (unfortunately) not the same thing, and every turing chip in that list has AVC1 support, but no AV1
The demo video plays format 397 which is av01 which is AV1, not AVC1 and doesn't reflect

although videos don't work well with av1 blocked with enhanced-h264ify

Compare

 mpv --ytdl-raw-options="" --ytdl-format=397+251 'https://www.youtube.com/watch?v=v2AC41dglnM'
 mpv --ytdl-raw-options="" --ytdl-format=135+251 'https://www.youtube.com/watch?v=v2AC41dglnM'

Also the video seems to be buffering a lot?

Waiting about 10 minutes seems to fix the issue.

Try to download the video w/ yt-dlp and play it locally (in your browser)

Re: [SOLVED] Videos on web browsers / electron apps stuttering

I think we can conclude that this is probably not a real issue because your hardware simply doesn't support Hardware Acceleration of AV1. To clarify a few things here: First, your browser reports that you will use the software decoder called dav1d. This, alongside the link I provided containing information on the supported codecs by your hardware, is a good indicator. The output of vainfo suggests that it works properly. So, the options to fix this problem are to maybe use a different browser with a plugin/addon to prevent AV1 videos. Choosing the right browser is a hard decision you should make for yourself, not only because of multimedia. What I can confirm is that using Chromium with the plugin called "enhanced h264fy" should work. But there is a catch: you need to pass the correct parameters to Chromium. Still, I want to remind you that Chromium might not be the best choice for privacy reasons.

In my case, passing the right arguments to Chromium is sufficient. After finding the appropriate arguments, you can then modify .desktop files to better integrate it with the desktop environment of your choice. "For example: chromium --enable-feature=...

Re: [SOLVED] Videos on web browsers / electron apps stuttering

Both mpv videos work properly: i believe sofware decoding is being used, but it still works fine, setting --hwdec=nvdec falls back on av1 and works fine on h264
yt-dlp video does not work in browser but works in mpv.
test-videos video works properly.
Also I find it important to add that this has only occurred recently, within the last 2 months.

Re: [SOLVED] Videos on web browsers / electron apps stuttering

mpv --ytdl-raw-options="" --ytdl-format=397+251 'https://www.youtube.com/watch?v=v2AC41dglnM'

uses yt-dlp to obtain the video uri and then stream that, so the problem is w/ the browser specifically - do *both* videos cause problems?

test-videos video works properly

In the browser or mpv?
What about this video (in the browser)

yt-dlp -f 135+140 'https://www.youtube.com/watch?v=v2AC41dglnM'

Re: [SOLVED] Videos on web browsers / electron apps stuttering

yt-dlp video in browser does not work properly.
test-videos video was in the browser and works properly.

do *both* videos cause problems?

Both work fine over software, and H.264 video works over hardware, but not the AV1 video.

Yep, did not work properly in browser. Works in mpv using software decoding.

135+140 is h264+m4a and should™ decode in HW?

Just to clarify, mpv seems to use software by default unless hardware is specified (e.g. --hwdec=nvdec)
From command 

mpv 'AC⧸DC - Thunderstruck (Official Video) [v2AC41dglnM].mp4' -v
[vd] Opening decoder h264
[vd] No hardware decoding requested.
[vd] Using software decoding.

And when hardware is enabled it still works fine:

Re: [SOLVED] Videos on web browsers / electron apps stuttering

New thing: I downloaded the fedora live iso, and youtube videos work. Switching to nouveau on arch does not change anything.

Re: [SOLVED] Videos on web browsers / electron apps stuttering

We're looking more at a problem w/ the browser than the driver (version difference between fedora and arch might matter, have you btw. tested eg. firefox?)
The irritating thing is that

test-videos video works properly

Which of the bigbuckbunny videos did you test (in your browser) specifically?

(1080p, 10s, 30MB)

Also, firefox was on 126.0 on Arch, and 125.0.3 on Fedora

Re: [SOLVED] Videos on web browsers / electron apps stuttering

The bunny is a mute…

yt-dlp -f135 'https://www.youtube.com/watch?v=v2AC41dglnM' # this is heresy

and test the downloaded musicless sadness in the browser.
This might be down to pipewire/pulseaudio - so please post your complete system journal for the boot: 

sudo journalctl -b | curl -F 'file=@-' 0x0.st

Re: [SOLVED] Videos on web browsers / electron apps stuttering

The news are 2 years old.
Unfortunately your setup doesn't show any obvious errors. The journal doesn't cover a GUI session/browser video playback? Or does it? Do you start w/ startx/xinit?
In that case please see the last link below and post your xinitrc.

I started with 'Hyprland', but it still does not work with a display manager enabled.

Re: [SOLVED] Videos on web browsers / electron apps stuttering

Does the issue remain w/ a fresh user account?
Try to move away ~/.config/wireplumber/

Re: [SOLVED] Videos on web browsers / electron apps stuttering

Do you have ~/.local/state/wireplumber ?
Did you try the behavior w/ a fresh user account?
