Solution

This doesn't happen if the patch is disabled, but then the buffering problem persists, which this patch was made to solve.

Additional context

This stuttering doesn't happen on every video, maybe due to the uploaded video's codec.
Some of the youtube channels I've faced this issue are known as (Tech Karan) and (Everything Android).

Compare the codec used in the unpatched app and the patched app via the nerd menu in YouTube

Try turning off iOS spoofing (which then uses Android VR spoofing).

Also verify Spoof device dimensions is not enabled.

Sure, here's the stats from original youtube app:

And the patched app:

Device dimensions patch is not enabled...
And yes, this issue doesn't happen with the Android VR spoof, just the iOS one...

Apparently late versions of iOS only support avc1: https://www.reddit.com/r/AV1/comments/16uy52m/comment/k2pxbwn/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

From what I can gather, that has a Snapdragon 712 and has hardware AVC1 support but not AV1.

I just noticed your logs show you are using a fork of ReVanced.

Check again using the latest official ReVanced, with iOS spoofing, the same video, and report back which codec is used.

Alright, I patched the app myself using the official patches(only selected the patches for ADs, spoof client and GmsCore while patching), but it's still stuttering with the spoof iOS patch enabled... here's the stats...

[LisoUseInAIKyrios]

It's correctly using vp9 (since the device av1 check did not pass), but it's still stuttering. Lots of dropped frames showing in the stats.

So the issue is not the codec, but something else with the iOS spoof.

[oSumAtrIX]

The unpatched app uses avc1 whereas the patched app uses vp9, probably that's why.

@YouSummoner what codec is used with Android VR spoof?

Stats with Android VR spoof:

[oSumAtrIX]

You previously claimed:

And yes, this issue doesn't happen with the Android VR spoof

In your latest picture it shows dropped frames though. So what now?

[YouSummoner]

I can't say about the stats, but I can confirm that no stuttering was visible to the eye while playback of the video. Though I did check again on the same video with Android VR spoof and here's the stats from that, this time it isn't showing any dropped frames.
