Stuttering in YTUHD 2160p but perfect in vanilla YouTube

[UprisingPulse]

Hi, I got iPhone 13 Pro Max, in the vanilla YouTube app from appstore I have the option to play 2160p resolution smoothly, however when I sideloaded YouTube with YTUHD, when I choose 2160p it stutter and buffer.

[PoomSmart]

That makes sense. Your sideloaded version of YTUHD probably doesn't include VP9 entitlement spoofing.

[UprisingPulse]

So you mean the problem is with the YouTube ipa itself or the tweak?

I tried it on my iPad Pro 2020 also same results, stuttering and buffering for anything above 1440p or above 1080 HDR.

[PoomSmart]

The issue is that you didn't compile YTUHD for use with your IPA with VP9 entitlement spoofing code uncommented.

[UprisingPulse]

Affirmative. And how can I do that?

[PoomSmart]

@UprisingPulse Assuming you can compile YTUHD from source, line 6-7 and line 60-65 are to be uncommented from Common.x before you compile the tweak.

I'm getting this error

[UprisingPulse]

Yes I have the latest build, I will reinstall it and try to work it out
Thank you very much, it’s working perfectly

[UprisingPulse]

Sorry to bother u again, but it’s not working anymore, even with ur deb and I complied you source and injected it, it stopped working, it stutter like before on 2160p resolution

[PoomSmart]

Reopen for later investigation.

[UprisingPulse]

I injected the deb you sent above to youtube 16.54.5, you can see the stutter after sideloading and enabling vp9 and 2160p res.

And this one I injected it with my complied deb

[PoomSmart]

@UprisingPulse With the latest version of everything, does it work? Can you also post the screenshot of "stats for nerds" for the video you are testing with?

[UprisingPulse]

Just tried, no it still doesn't work, I have the latest YouTube with the latest everything "tweaks".

This is the screenshots:

Got this error again. using latest THEOS and 15.0 SDK

[PoomSmart]

Copy Xcode’s SDK into $THEOS/sdks and then add PrivateFrameworks from the latest SDK in theos/sdks repo to it.

[UprisingPulse]

Copied Xcode SDK (15.0) to sdks and added PrivateFrameworks from the latest SDK 14.4 from theos repo.
Still getting the same error.

[PoomSmart]

@UprisingPulse Could you try adding a framework in Makefile like this:

$(TWEAK_NAME)_FRAMEWORKS = Security

[PoomSmart]

Also, this dylib you may use: https://github.com/qnblackcat/uYouPlus/files/7738656/YTUHD.dylib.zip

[UprisingPulse]

Tried my own complied deb and yours dylib

I got this in both:

still it doesn’t show HV but not stuttering for now, need to test it longer.

[UprisingPulse]

It still stuttering

[qnblackcat]

For me, it only happens when playing at 2160p. 1440p is fine. YTUHD 1.2.6
