Lagging on Youtube while watching 1080p 60fps and 4K

Hi friends, i have a problem while watching 60fps and 4K videos in Youtube. When i set resolution to 1080p 60fps and increase video speed the video starts to lagging and loses smoothness. I try this on Youtube vanced and official youtube app and result is same.
Also in 4k i have same problem.
I am waiting for your answers.
My device
Huawei P20 Pro CLT-L09
9.0.0.163

Latest youtube vanced,
4K 60Fps HDR - 1,5x playback speed (although purpose of 60fps was for slower playback to be honest)
all work fine.
Is your battery saver on ?

Could be down to your Internet speed and not your phone. My phone doesn't have any issue with playback lag at higher resolution and frame rate.

I have no problem on 1x speed but when i switch to 1.5x or 2x video loses smoothness. When i enable performance mode sometimes fix issue. But still i don't understand the reason of this issue

Hello , I have the same problem. Still on 8.1.0.156. Using std youtube or vanced.. when in portrait the video looks awesome and smooth. On full screen becomes laggy and slow in 1080p60. I would like to add it to game suite app but you can't. Still looking for a solution....
SOLVED. Was using Fluid Navigation Gestures App and that was causing the lag in Youtube Vanced. Just add YT to blacklist and now works fine.

The problem is your hardware not the device, To fix this you have to go in developer options in settings and turn disable Hardware overlay on. if you dont have this option update your device, if this also does not work get a new device.

10bit HEVC Extreme Black Crush after using Camera App

Somthing I noticed a few times on my Note 9 was that some times my media files would play very dark. Now this would only happen with 10 bit Hevc files.
So I did some trouble shooting and found that whenever I start and exit the camera in "Photo" mode this would happen.
I have put a pic for a 10 bit hevc video paused on the phone, in both instances all settings are the same, the pic titled "No Black Crush" is before using the camera and the other after using the camera and exiting in Photo mode. From the pic we can see that one pic is significantly darker and details are lost (eg. White spots on the sign and some background stuff).
The only way to fix the black crush is to restart the device.
Would really appreciate if some one out there that is using an Exynos version and plays 10bit hevc videos on the phone would help in testing some stuff out.
Edit - Ok so I guess some more info is in order.
Device info - Note 9 Exynos (Model SM-N960F) on latest official build and NON ROOTED
To replicate issue download the video in the link (https://drive.google.com/open?id=1QR-5JEWNOFI3nbvbLR_80Z7BgA37Dil_)
1. Restart phone
2. Play the video using stock video player (keeping Video Enhancer on makes noticing the bug easier as screen is brighter, Video Enhancer off should also work)
3. Open stock camera and make sure "Photo" mode is selected and then exit staying in "Photo" mode (switching camera modes wont let the bug show up.)
4. Play the clip again. BOOM everything is a dark mess.
5. Restart phone and play the clip again and everything looks clear again

does changing the the screen mode from adaptive display to amoled cinema or even basic help at all?
if you get inconsistent results then it would seem that is would have something to do with the "auto" nature of the display mode. moreover the ambient lighting in the room you are watching might also be a cause. adaptive brightness might produce different results and might be tied the the screen mode as described above.
so remove auto brightness and put screen mode to Amoled cinema or even basic if you really want to compare apples with apples.

Since I have been seeing this behaviour for some time now I have actually checked to see what was triggering it. Changing the screen mode does not help. Also in the pic I attached the brightness level is the same since adaptive brightness is off.
Now I understand where you are coming from but this is not a screen illumination issue. If I play a H264 file everything works fine no black crush even HEVC files which are not 10bit play correctly, the issue is only with 10bit HEVC files.
Oh and am not sure if you are aware as to what "black crush" is, it basically is the tendency of amoled panels to make dark areas so dark that u loose details in the video. In the pic I uploaded u can clearly see that one pic is significantly darker than the other even though all settings are kept exactly the same even the brightness levels are the same but dark areas appear much too dark when the bug is triggered.

Ok, so you are right. More info definitely needed so I have updated the original post with details on how to replicate the issue and have shared a clip as well that you can download and play using the stock video player.

Below mentioned steps should work to replicate the bug.
Testing to be done on Exynos version.
To replicate issue download the video from the link in the very first post
1. Restart phone
2. Play the video using stock video player (keeping Video Enhancer on makes noticing the bug easier as screen is brighter, Video Enhancer off should also work)
3. Open stock camera and make sure "Photo" mode is selected and then exit staying in "Photo" mode (switching camera modes wont let the bug show up.)

so i forgot before leaving for home to do the test while having access to an other phone taking a picture of both scenarios so that i could analyze both pictures. but by testing it right now doesn't seem to make any difference.( picture seems ok.) but i am using a custom rom and kernel and system is heavily modded so who knows that might have had an impact. also when you do switch from camera to video, do you remove the camera app from memory( remove it from recents? i left it and no change)
for what's it worth im on a july build...
ill try again tomorrow this time taking before and after pictures

Ahh so I should have mentioned. Am on July official build, non rooted (still have 2 months on the warranty). I guess rooting and a modified system would have an impact on the issue but thanks for testing out. Out of curiosity what is your setup? Which custom rom and kernel are u using and what extra addons if any.

No Video Playback in Native Gallery App.

I'm having a strange issue where no videos, either taken myself or downloaded from elsewhere, will play in the Huawei Gallery app. They all play correctly in Google Photos and when sent to other people.
I've reset the Gallery app data twice and tried various video formats and none play. It simply kicks me back to the previous screen (camera if trying to view straight after recording or Gallery main screen if trying to access via gallery).
I'm not sure when this issue started but it's not always happened and didn't start as soon as I upgraded to EMUI 10.
P30 Pro VOG-L29 all stock on EMUI 10.0.0 with all updates installed.
Any help is appreciated,
Luke.
Edit: an example of what happens after recording & trying to view. https://photos.app.goo.gl/EZWGCqtkkk7LprjL8

Din you uninstall Huawei's native video app?
(com.huawei.himovie)
If yes, that's the problem.
Reinstall it via adb.

I don't remember doing so but it appears I have uninstalled it; where is best to get the APK to use?
EDIT: disregard the above question; quick Google for the full path took me to the play store which showed HUAWEI Video as still installed. Uninstalled it which takes it back to factory settings and this fixed it. Re-updated the app via Google play then via in app prompts and it stops working so it seems to be an issue with the update.

Question Video is Rendering Over Sharped in Streaming apps like YouTube, Prime Video and Local player's also like MX player etc.

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 the same issue ... i sent it to mi store to check it up for a few days and they said it was alright ...
i also checked another note 10 s device in the store .. it has the same issue
the issue exist in youtube and google chrome ....
not sure if its a software issue that will be fixed or bad qc

since u posted 20 days ago .. did u do anything about this issue ?

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

i kinda like it although it might have to do something with miravision
best is to ask people using realme 7 and redmi note 8

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.

Has this been fixed? is it even fixable via firmware updates?
As far as i know the Redmi Note 8 Pro has the same problem and still has it to this day
I was going to pick this phone up for my mother by this is definitely a turn off

try chaging the codec override in vanced setting , also to enable extra options in the override menu tap many times on about to unlock hidden setting

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.

I also have the same problem on JMGO O1 projector. Every time I play another video I have to go into settings and adjust the sharpness, from 0 to 1 then back to 0.

Question 11T Pro HDR doesn't work on YouTube videos

Hi, this is my first post, i bought 11T Pro few days ago and noticed problem that HDR doesn't work on YouTube videos (which has this option). The colors are faded, and brightness does not change. But WHEN I ROTATE THE PHONE HDR ENABLE AND WORK FOR 0,1sec, then goes out...
I did a hard reset and HDR worked for 5 min.. brightness were changing and the colors were deep. But when i play next video (not changing any settings) HDR stopped working. I try reinstall YT app, without changes. Please help, it's very annoing..
MIUI 13.0.20
edit 1. Just a moment ago i discovered that HDR work fine when i press (up or down) Volume Button, but when sound level goes out the HDR stopped working. Any ideas?

edit 2. I found on reddit info that disabled HW overlays may help. And it worked for a while...
Fact: after reboot and first launch of YT everything works perfectly, however when I exit YouTube, lock the screen and enters back YT it not working and the colors are washed out. Only again reboot helps at this point. does anyone have ideas? can you check it on your devices?
The video which i use:

This is happening not only in YT, also Netflix. I tried to find some solutions but for now the only one is disabled HW and watching movies. Miui 13.0.7 xiaomi.eu on *.0.6 problem also existed.
But this video from your link works fine for me but Netflix not.

I agree netflix works properly after disable that option, but YouTube works as it wants. One time I turn on and it's fine but other time HDR on youtube doesn't work. I don't know what it depends on. Does anybody have an idea?
ps. sory for bad english, i am using a translator
