Random youtube framedrops.

Open SleepyAlpha opened this issue 1 year ago • 7 comments

Lately, I have started noticing that YouTube has been randomly dropping frames, and by "dropping," I mean in a noticeable way. Is this a known bug?

OS: Windows 11 Pro Browser: Microsoft Edge 114.0.1823.67 Other extensions used: Ublock Origin

In stats for nerds, there is an actual stat for dropped frames. Can you confirm if it's reporting the dropped frames and how it's interacting with sponsorblock? (After skips, on load, etc)

Yes it's dropping and it is at completely random times.

Some times it drops a ton of frames but the playback remains smooth just like in the video below, other times it's like a 30 fps video, since it's so random it becomes hard to capture.

You can see it dropping frames beggining at 12:08

Edit: Forgot to mention this happens in both Microsoft Edge and Google Chrome, tested on Windows 11 Pro and Arch Linux

Hmm, this is nowhere close to any sponsorblock segments and it seems to be consistently dropping frames at 15-20fps. If you notice, the frame it starts to drop frames, your internet connection speed also drops by 10,000 kbps (12:14.154) and again to 15fps/20 at 12:23.916

1st time noticing that, my internet is crap but the buffer is maxed out, so it should not be the issue.

Also the internet speed does not explain why everything works fine without sb installed, but now that I think about it, it is really weird how it drops frames consistently.

It's not close to any sponsorblock segments at all, if you want you can try testing it on a video without any sponsorblock segments , I suspect it might just be a coincidence or some cache somewhere is being populated while you have sponsorblock enabled.

I've been having this issue as well. I'm running Firefox on Linux. With SponsorBlock disabled, I no longer get framedrops. I get framedrops with SB enabled regardless if a video has any SB segments or when video playback is close to a segment. When I skip back to the dropped portion of the video, the video buffers.

-- If it helps any, I'm running an older laptop with dual core and integrated graphics, but it plays video just fine both inside and outside the web browser.
