Hello Everyone,

A few days ago, I purchased the Redmi Note10s, which worked very fine in every aspect of the smartphone, but I've found issues of video rendering in apps like YouTube and others even in 1080P.
But The Strange thing is that while playing the same video on the youtube website using Firefox browser it renders perfectly and Amazing.

Below I've attached the screenshot of the same video playing in those two different apps.

YOUTUBE:
As You'll see below the SS of the YouTube Sample is Over sharped and isn't pleasing to the eyes

FIREFOX:
In the samples of Firefox, it renders the way we want with perfect colours and sharpening.

Is this problem with Software or GPU rendering, I don't know. If anyone having this phone please share your opinions or thoughts on this, and also let me know if anyone facing the same issue.

P.S: this is my first post on XDA community, hoping XDA community will help with this problem.

I have come across the thing called video decoding, which is done mainly by GPU or processor. In our phone, a MediaTek processor is used which is using a technology called MiraVision to render the HDR video which causing the issue while playing video in lower quality like 480P. Some solutions I found on Reddit is saying to disable the hardware overlays to solve the issue, as this problem already faced by redmi note 8 users. But didn't solve our issue.
But idk why I'm used to this as video of 720P is much sharper and feels good now

It maybe an issue with MiUI's VP9 renderer (VP9 is a new codec developed by Google as a free alternative to HEVC ,or H265).
The codec is used by default by YouTube since it offers higher compression compared to previously used H264 codec (AVC).
The codec is all fine, and it is absolutely recommended to use it since it offers better clarity and saves data at the same time.
The problem is with MiUI's VP9 rendering algorithm which is over-sharpening the video. I suggest you to contact Xiaomi to fix the issue, and disable VP9 in YouTube Vanced for time being.


If the above solution didn't work, you may try changing the decoder in MX Player [Try all 3 decoders - HW, HW+, and SW.]
If you don't observe any changes, use the mx_aio custom codec.


Pls reply if this worked or not, so that others would benefit.

    Begonia user here. .as for most possible fix
    change "ro.vendor.mtk_pq_support" from 2 to 0 (in Vendor/Build.prop)

    *well, it need root access to do that.
