Mi box s 4k and on all Xiaomi devices I get video pixelation issue? - Redmi Note 8 Pro Questions & Answers

Broken H.264 (avc) codec bug!
Problems:
0. Artifacts and ghosting
1. There is a shadow left from the last image onto a black scene that comes after.
2. There is a trailing edge of every lighted scene around the picture.
3. The problem is wide, not only related to single app.
I did notice on Xiaomi devices pixelation on videos.
I have mi box s 4k and chromecast ultra while there is no pixelation for the same video for chromecast ultra I'm getting pixelation issue for mi box s 4k and redmi note 8 pro.
This issue I did notice it for local videos and youtube app (I didn't notice for netflix).
So I did try some methods my self. switching to sw decoding on mx player got pixelation fixed but this isn't precise solution cuz I did read somewhere that hdr is gone for sw decoding and youtube app problem stays.
For Xiaomi devices I did find a video on YouTube. so on mine redmi note 8 pro I did as the video told.
the video did told me to turn on hw overlays so I did turn it on and I got pixelation fixed!!!
youtube .com/watch?v=MGxh2vCmR1E
But for mi box When I turn on disable hw overlays I'm getting no screen I'm only getting audio what could be the cause of this could someone help me to turn this on?
Or is there any other solution how I can fix the pixelation?
Update:
İn mi box s 4k There is no pixelation in apps like netflix!!! but vlc, mx player and chromecast built-in playing local video file is the issue getting pixelation in hw decoder!
imgur. com/a/OO2R8VI
Example:
Hw decoder: imgur. com/US8Xzor
Sw decoder: imgur. com/fUzwKvw
You can see white line in hw decoder.
İn sw decoder the white lines pixelation is fixed.
Update 2:
Someone told me this is a known broken H.264 codec bug! (avc bug, h.264 and x264) I think that person is right! I did encode my video to H.265 and the pixelation was gone!!!
Does someone When did this problem start?
İt is aggravating I hope Xiaomi will fix this problem soon.

[Solved] Video camera not showing full resolution

When I go into video recording mode, the max resolution is displays is 1280x720 even though this phone supports 1080p. I checked the hardware with software info apps and the camera is supposed to be able to capture 1080p as well. Is this a hardware or software problem? Anyone else not able to record video in 1080p?

not quite.....i think SGS Glide only has 720p....
there is a disclaimer at the bottom, but after reading a few reviews of the device, everything says 720p, no 1080p.

That's weird because the video camera is reported to support up to 1080p in apps like Elixir and I vaguely remember rogers showing 1080p recording unless it's been changed now.

In fact, it was changed, just like the NFC, crap, no 1080p video recording, no NFC, what the f*ck was Samsung thinking ?

Google Photos does not show 1080p 60fps or 4K video?

I've noticed that any 60fps 1080p video or 4K video that I take on my Pixel XL and upload to Google Photos always shows up as plain old 1080p. Has anyone else noticed this?
I've noticed that if I download the same video in Google Drive to my machine, 60fps or 4K remains intact- but not when playing back in the browser (either in Drive or Photos).

When playing back in photos, do you adjust the quality in the bottom right? (Similar to YouTube)
Update: I see now. Even though it's got the quality options in the lower right, the options are limited to Auto are various resolutions from 1080P on down. No 4k or 60fps. Weird.

Yep very weird. I haven't seen anyone else talk about this issue either.
I am guessing that like YouTube that because the screen of the Pixel XL is 2k it doesn't give the option for 4k play back on the phone itself
That's a shame.... It should at least do the 60fps

Is X265 10bit 1080p mkv supported?

Is honor 8 pro capable of playing X265 10bit 1080p hevc video?
I've tried samples from jelly fish with stock player, mx player n vlc. None works. Tested the same on friend's op3t phone n it played smoothly with stock player. Even X265 10bit 120mbps 4k video was played without lag on op3t. But this honor 8 pro cant even play 5mbps X265 10bit video?
So is this hardware issue on honor 8 pro?
Any suggestions??

Yes. It's absolutely capable. I just tried. Make sure you're using the latest vlc 3.0.0

Yes i m using vlc 3.0 but no help. Any settings to change? Attached is the screen grab. It plays for few secs and then hangs.

I really have no idea.
Try turning the hardware acceleration to Full in Vlc.
Are you on EMUI8?

Hardware acceleration is to full and m still on emui 5.1, waiting for ota update.
If its of any help, attached is the screen grab from stock player.
Playback is smooth but with distorted colors.

I too had this problem on EMUI 5.1
Wait for the update. It may solve the problem because I didn't encounter this problem on EMUI 8.

Thanks for your help!! Will update once i get oreo update..
So my phone has been updated to emui 8.0 and phone has been factory reset post update but this issue of non playing X265 10bit videos is still there.
Any advise?
1080p hevc mkv videos cannot be played with inbuilt player (due to colour distortion, though videos are played). With MX player, HW decoder is not supported; video automatically starts playing with SW decoder. With VLC full Hardware decoding is supported without color distortion (but still playback is not that smooth, sometimes even videos got stuck).
Overall video playback on honor 8 pro is poor. So don't expect much.

M facing same issues that u highlighted above. Earlier in my posts I was told that this device is capable of running hevc 10bit videos so I thought its my device specific issue.

The chipset is surely capable but I don't know why this happens.
Vlc does play the video but if the video is skipped, it gets stuck on that frame.
Maybe because the kirin chipset isn't widely used and thus, there are optimisation issues with many apps. I get dropped frame rates almost in all games and this baffles me because the chipset is fairly powerful.
I am not buying device with kirin chipset again. Lots of optimization issues with 3rd party apps.

it would be really sad. u've contributed a lot to this community. to say this means we won't see you in the honor/ huawei section that often since they usually stick to their own processor.
but yes, it does seem sad that there's really not much optimisation... though for the GPU, it is still MALI, which is also on Exynos.
i can only hope things will be better and Huawei/ honor can really work with more developers.

I can't really say if that first line was sarcasm or not.
This device can't play any game without skipping frame rates. It lags pathetically on playing temple run 2.
There are clearly optimisation issues for 3rd party apps because they have optimised it exceptionally well for their own apps and the whole software. This ruins the overall experience because as the OP stated that a device with SD821 plays 1080p 10 bit x265 videos smoothly while this doesn't.
Exynos devices may not be relying from this same problem because Samsung sells those devices in a lot more number than Kirin devices.

why do you think it's sarcasm??
as for Exynos devices... they also use MALI GPU, though it's a diff variant of the chip. still, if they can get it optimised... i guess we can hope it's the same for Huawei/ honor. after all, Huawei/ honor is also one of the top manufacturers in the world right now.

I felt it was sarcasm because I don't think I have done anything major for the community here. I am not a dev [emoji12]
I haven't used an Exynos device. So, I am just guessing. Yup, I know they both use the same GPU but with lesser number of cores though. Maybe that's the root cause of this or it's just pure optimisation problems, don't know because reviews didn't show any such issues with this device. I am really confused.

Yes even i am also confused as reviews shows no such issues but it can be possible that not many ppl really tested these specific vidoes on this device. Hence I posted screen recordings of my phone. Need some more testers to see if I m the unlucky one.
Stock player plays video smoothly but with lot of color distortion. VLC just hangs after 1sec and MX player plays through SW decoder with lot of stuttering. XPlayer from Google play plays video much better but still stutter a lot. Overall you can't play x265 10bit HEVC videos with higher bitrate n framerate and of higher file size on our H8Pro. What a disappointment. I tested the Jellyfish sample video which was around ~33mb and main10
Not only in hevc, x264 video playback also have a bug. The 'blacks' are not shown properly in HW decoding of MX player or inbuilt player or VLCs full Hardware decoding or any app using internal codecs including video playback in YouTube app. There is a permanent 'tint' over video (only video screen) when played in these ways. The tint is absent in SW decoding mode of MX player which means the fault is in internal decoding.
To check this pause a black scene of widescreen video (so that there are top and bottom black bars). The black bars are distinctly visible in inbuilt player (and other playbacks that use internal decoding); But screen is full black (black of screen becomes same as that of bars and so can not be distinguished) when SW decoding of MX player or VLC (No harware acceleration) is used.
Not only blacks become greenish black but all colors become slightly dull compared to actual.
This most probably wasn't before oreo update.
Also there is one more magic to it. I tried to attach screenshot, but the screenshots are clear (tint is absent), even when screen recording is on tint dissapears and reappears as soon as screen recording is turned off.
I had to take shot from another phones camera. Pics in attachment is of same black scene (video paused). Screenshot is completely black while photograph shows how it actually appears (distinct top and bottom stripes).
Eye comfort or display color settings has nothing to do with it.
I already reported this issue to honor customer care but I don't think it would do anything.
Anyways, there is NO way to fully enjoy videos in our honor 8 pro. We have to just accept this. To avoid frustrations: stop downloading x265 video, stop comparing with other phones and simply accept what we have.

Question Is the display broken? Colors?

I noticed a problem when watching Youtube videos. For example this video
I can watch that video just fine on a Poco x3 pro (also SD 860 and 120hz), but on the Pad 5 there is a problem. I don't see anything until 10 nits in the video. I also cranked up the brightness to the max. On my mobile I can see something much earlier - with normal brightness.
Does anybody have an idea what the problem could be?
Mine starts from 1 nit onwards, if I enable screen balance app 0.5 nit. Tbh I hate the screen. This device is called 'media consumption'. I can't enjoy a movie when blacks are absent
I am regretting my decision tbh. Should have bought a basic oled device.
I just realized that when I use Newpipe instead I can see the colored boxes from 0.2 nits onwards. So it is not necessarily a screen issue?
I am wondering what could be the difference between Newpipe and Youtube?
Could also be youtubes own codec for videos. However, the ips panel used on mi pad 5 lacks any depth or contrast. checked couple of reviews. One says contrast is 1300:1 the other says 550:1 . What I can tell is, I am not gonna watch a movie on this tablet.
I was reading someone today saying that YouTube only displays HDR with the AV1 codec.
No idea if true or not
With max brightness after 2 nit , in normal brightness after 3 nits
Thanks for your answers and testing!
I guess, there is indeed something broken in the Xiaomi Pad 5. I noticed that the display problem only happens when you play HDR movies. The Netflix movie quality is good in my case. but only because my plan does not include HDR apparently. HDR movies look ok with Newpipe, because Newpipe does not support HDR ...
HDR is basically broken on all Pad 5 tablets. Wow!

Seems to be multiple Codecs for hdr.
Well I am stuck w this tablet. Have to find a way to enjoy it, somehow
Thank you for the added information @parser
What application is that? Very cool the way it displays all formats available

My pleasure,
This is an app called smart tube next. Just Google it. Devs name is yuliskov. It has a github page.
Even though I have youtube premium, I use his YouTube app on my firetv.
Ah yes, i hear it is a superb application.
I too pay for Youtube Premium, but will load it up on my Shield TV as Shield users mention how good it is, all the time.
Thank you! @parser

Question 960 FPS mode is broken

Hello!
Recently I bought a Xiaomi 12X phone, 8/256 variant, OS is MIUI 13.0.3.0(SLDEUXM).
I have a problem with 960 FPS mode, it works, but it output garbage video files.
This is with H.264 encoding
Your browser is not able to display this video.
The H.265 one isn't playable, but I'll throw it here. This one should be a green hell of a mess.
(You can play it in external player, like VLC. Right-click the video, copy the video address and paste it to VLC's "Media-Open Network Stream")
Your browser is not able to display this video.
Is this a hardware or software failure?
Thanks!
Edit: quick update, so the problem only persist if my phone is set to my native language (Hungarian). If I set the phone to English (Great Britain), both H.264 and H.265 videos are perfect.
So there is a software bug there.
I have the same problem, i download the apk of new xiaomi camera app and has Better quality but not perfect
