why video apps do not utilize the entire screen?

Slingplayer, Xfinity, MX player etc...aside from Google Play movies, I have not found a video app that uses the full 6" screen. Slingplayer and Xfinity leave what looks to me to be over 1/4". Is this universal or an issue with my phone? Is there a setting somewhere I haven't found to force full screen for video?
I am completely stock 8.1 at the moment...I don't think I should have to do something via adb like forcing immersive mode for something like being able to use my whole screen to watch video???
thanks for any and all input

I don't use Sling Player and no longer have Comcast cable but I can use the full screen with MX Player. However that isn't the default. The Pixel 2 XL has an 18:9 (2:1) screen. No video formats I have even seen use that aspect ratio. That means any video you watch that takes up the entire screen must be cropped.
I still don't understand the popularity of the taller aspect ratio.

Soon more apps will implement the pinch to zoom feature like YouTube has.

Actually an anamorphic movie should make good use of the screen. I played a Netflix movie (I think it was hateful 8) and it filled the entire width of the screen, with much smaller black bars on the top and bottom like you'd have with a16:9 screen
Hulu doesn't seem to take advantage of this, tried Future man which is filmed in an odd aspect ratio and it has black matte all around

It is pathetic, great phone but media streaming is certainly hampered compared to the note 8

Question Camera software and HDR integration with other apps

So one thing that I understood from the launch live is that google has collabbed with Snapchat to bring full implementation of HDR within the app.
My biggest doubt is.. will it also fully integrate with all the other social network apps or not? I mean apps like TikTok, Instagram and most of all, Whatsapp..
What makes an android phone so bad for socials is that they totally cripple camera performance once you use a third party camera app. On the other end iPhone's do it perfectly. If only the Pixel filled this gap, it would be a no brainer choosing Android over iOS..!
I currently have a Pixel 3 XL and every time I use the camera to take photos in Whatsapp or videos in tiktok, its utterly ugly, it looks like the pic was taken from a Galaxy s4.

I'm still not so sure if we even have "true" HDR10 (or better, like Dolby Vision on Iphone 13Max) on the Pixel. Did anyone actually try to look at picture/videofootage at a HDR capable monitor/TV and did HDR kick in?
As far as I know, it's all some fake-ass SDR vivid-algorithm BS.

I guess we/you'd have to transfer footage of your phone (video/photos) to a HDR capable device (like an LG CX or something like that) and see if HDR kicks in. It's also possible to detect this with Windows tools like MediaInfo. If the video is recorded with HDR it will have a color space of BT. 2020 also know as REC.2020.
Even though it's kinda tricky to determine if it really is shot in 10bit. There is a differenec between color depth and color space, meaning a video can be shot in 8bit and can still output a HDR signal, even though it lacks all basic features that HDR should offer. This whole HDR story is a joke at this point, it's basically broken in Windows, the whole industry is split in several factions (HDR10, HDR10+, Dolby Vision...), there is almost no cross-compatibility and then you can't even trust the output of a file, as explained earlier.
It sucks, and it sucks hard. I - for example - tried to get Mass Effect: Andromeda working with Windows 11 (Dolby Vision) and stopped after about 9 hours of troubleshooting because of Black Screen problems, rainbow color issues, crashs, forced restarts because the Windows UI crashed/became invisible...
HDR is just a mess. It only works well if you put a streaming device directly into an HDR capable Television and use Apps like Disney+, Netflix, HBO MAX or something like that.
It's a shame, because footage shot in true HDR look simply stunning.

I haven't had any issues in Windows with my second Monitor that has HDR capabilities....but there are times when I turn it off because it doesn't look the best in some games.
Mass Effect Legendary Edition was having wash out issues on my pc until I turned it off

Question HDR on Mi Pad 5 doesn't work as it should

Hi guys, I've tried to watch some movies with HDR (1080 and UHD movies) but the image is really really dark even on max brightness level in a dark room; I've tried both Plex and MX Player Pro but still nothing, even the HDR videos on YouTube are very dark.
Also I am sure that the HDR of the video works correctly because on a samsung galaxy s10 it works perfectly and I can see it very well.
Here is a comparison to show you the difference indicatively (S10 VS Mi Pad 5): Imgur Comparisons
Does this happen to you too?
My tablet: International Xiaomi Pad 5 with MIUI 12.5 (12.5.8.0 Stable)

different display, different hdr format. s10 use hdr10+ with a amoled screen so def better than ips panel with standard hdr10.

It's not a question of better or worse panel, here with the mi pad 5 the HDR does not work completely.
It is sold as HDR10 & Dolby Vision certified but then they don't work at all; I've also seen a user on reddit report the exact same thing so I'm starting to think it's a software problem...

when you open hdr video, if it's too dark, yes, that's because hdr is working, but ips panel is not really good at dark color so that's the problem.

I also subscribe to this issue, I own the Non-Pro and HDR videos are way too dark, some movies on Netflix are almost impossible to watch despite cracking the brightness up manually (it makes the subtitle too bright compared to actual video).
I hope Xiaomi will implement a fix in future updates.
Also, when playing Dolby Vision files, the aspect ratio is something bad such as 20:9 (actual videos are played in some ultra-wide aspect ratio), the actual dark frames on top and bottom eat 50% of the vertical space, this is also a bug.
If I knew the software is that bad I would had gone with Samsung tablet instead.
@OP is not wrong at all, this is a software issue, the screen is bright enough for HDR content but the software is lacking.
Bug has been reported on a lot of forums, including here :

Thanks for confirming my theory, it needs a bug fix otherwise so the device is really unusable for HDR content.
Have you also reported this to Xiaomi hoping that it will solve as soon as possible?

The problem is that hdr videos are made for really bright screens (hdr10 1000nits, hdr10+ 4000nits, DV up to 10tsd nits). Now on TVs this is normally not a problem because the TVs know what there max. brightness is and they can adjust the brightness of the movies. The tablet itself does also know the max. brightness but the Netflix or whatever player does not (or at least it does not work). What you can do is, use a player like mpv, and set the target-peak or, which i would not recommend, set the video brightness. Sadly, once again, the users who pay and watch movies legally are the ****ed once.
Its a night and day difference.

By your logic, DV must be completely black but instead, it's the only HDR that works on Pad5.

No, bad wording. It is made for screens up to ...nits. Now when you want to display it on a screen, not as bright, you need to map the colors to a lower brightness. And you don't wan't to simply cut it off on the dark or bright side. But you can tweak the mapping and the default players are really bad at it. Also i have no clue why DV should be the only one working.

I also highly doubt that mpv fixes anything. It uses the same HW decoding than any other player for DV or if it uses the SW decoder the colors will not be correct. Here is the issue: https://github.com/mpv-player/mpv/issues/7326

You don't understand. DV _and_ hdr10 should work, but right now it's only DV and only with mpv and JP. The image is dark but not too dark as with hdr10. Just Player has a bug with black bars (it's not the aspect ratio because the image is cut on top and bottom.), not colors.

I don't wan't so sound rude but mpv just does not support DV. IF mpv playes your DV files i would be highly interessted in those files. I can imagine that you have some hdr10 compatible DV files? These will play in mpv just like hdr10 files. You can check with mediainfo and look for the HDR format string. E.g Lotr DV BD would be :
Dolby Vision, Version 1.0, dvhe.07.06, BL+EL+RPU, Blu-ray compatible / SM PTE ST 2086, HDR10 compatible"
you can also see the mastering brightness here
Mastering display luminance : min: 0.0050 cd/m2,m ax: 4000 cd/m2
Also the cropping for files happens on all DV files (that i could find). All of these players have in common that they use the HW decoding for DV and afaik there are no DV players which do not use HW

JP plays it perfectly (or ok) without cropping problem and mpv has broken colors (so it really can't play DV).

JP has cropping&brightness problems, mpv doesn't. But it looks like mpv is using tone mapping (?) - if you pause the file in VLC and tilt the pad the image would be the same as in mpv.

IMO this is a limitation with the physical screen itself, the fact is pad 5 only had a peak brightness of around 500, 478 nits iirc. Trying to play HDR content on a 478 peak brightness screen is impossible without doing some sort down- "tone mapping" which if it does, it's not HDR anymore, just capable of displaying HDR video. (the S10 iirc has 1000 nits max brightness and can peak to 1200 when required on a short time, that;s why the dark part is clear there).
on a 478 nits screen, even if you crank the brightness as high as it could, the dark part of the video is probably too crammed together, thus you're seeing a crushed black on HDR videos, where the dark part actually blends into a blob instead of just being really dark with some sort of defining shape clarity. The only solution is to change the tone mapping to SDR (BT.709 color space) either by transcoding the video itself or use a player with a tone mapping function (which if exist only useful for video files and not streaming services).

You talking about marketing numbers. Here is a test of S21 https://www.gsmarena.com/samsung_galaxy_s21-review-2218p3.php 416 to 856 nits. https://www.gsmarena.com/xiaomi_pad_5-review-2317p3.php pad5 has 478 nits and they guessing there can be more "Unfortunately, there is no Sunlight Boost even if the settings page suggests that. Maybe it will be enabled with a future firmware update, maybe not. Still tablet can be much brighter when watching HDR content, of course,". Iirc there was a review with 500+ nits max test with this Boost.
And the question is why there is only one player that can show you decent results with dv&hdr10 but has a cropping bug? Why Xiaomi with these hardware specs marketing it as compatible when even their own player can't play this content with decent results?

Updated to miui13 and it looks like the cropping problem on Just Player is gone.

I will refer to displaymate, while 400-800 nits are brightness in manual mode, when used in automatic brightness at high ambient light it could bring up to 900 nits for 50% apl, and 1200+ nits for 1% (which is probably where the 1300 nits marketing came from, while 1% APL is practically useless it's not entirely false either).
I did once owned an S10, and when you play HDR content, the screen will enter that automatic brightness mode, as it does becomes really-really bright, as if I was using it outdoor (high ambient light). So I would assume when comparing HDR vs HDR then the S10 probably should be assumed operated at 800-900 nits. Playing SDR content, you can't achieve the same brightness when playing HDR. I can't comment on s21 since i don't owned one, and can't tell if this automatic brightness thing still exist.
This is the same issue with HDR400, while by specification it is HDR, it sucks. And pad 5 being "Support Dolby Vision" is not equal to a brilliant dolby vision experience, it could be just technicalities that means that it could receive dolby Vision Input.
HDR10 contents usually are mastered at 1000-4000 nits, (I would assume DV is around that or bit higher). HDR TVs are usually only start to have good HDR experience from 600 nits or more, 1000 nits preferable. So I really can't complain if I don't get the same experience with seeing HDR10/DV on a 1000 nits TVs.
OTOH I do agree that there's also a software issues because the inconsistencies I've also experience, like when playing HDR content, even when i pump the brightness to full, it felt like it is not as bright as playing SDR at full brightness. And playing HDR10 in youtube is usually just fine (idk if youtube tone-mapped the HDR), only when playing hdr10 video files or streaming service like netflix/prime that the issue exist.
The only thing I wish it had is a turn off HDR switch or tone-mapping enable switch. Like most dark scene on netflix with DV are unviewable in this device, because it's way too dark, and I'd just rather see the SDR version.

Youtube app doesn't do tone mapping but you can manually set quality to SDR in the smartube app.
With files (or netflix), if it's too dark, you can set the color scheme to "standard" but the image would be low saturated or use built-in brightness&contrast settings in mpv (+10 both is good).
Tone mapping is an app feature not global, so until Netflix does something you can't do much. Only fake the hardware id/specs that it can't support HDR (idk if it's possible).

Just some more info on mpv with hdr (all for normal hdr, no DV):
Use this if you want to use the hardware decoding that normal player use (like the integrated video player):
vo=mediacodec_embed
hwdec=mediacodec
wid=(intptr_t)(*android.view.Surface)
this will directly use HW decoding and present the result on the screen.
Use the following if you want more details in dark scenes (i think this are the default settings):
hwdec=mediacodec-copy
gpu-context=android
I don't know exactly what mpv uses internally here but the main idea is to use the HW decoding, copy the image back to memory, do some post processing and present it on the screen
What i like to use:
hwdec=mediacodec-copy
gpu-context=android
hdr-compute-peak=yes
tone-mapping=hable
Mostly the same, but not as aggressive in my opinion (only personal preference).

Question Really no fix for HDR/DV dark scenes?

I was really satisfied with tablet until I started to watch DV and HDR movies (netflix, hbomax, plex). Searching internet and I could not find nothing to get rid of "ultra" black dark scenes in videos.
Is there any app that would change gamma of video or something like that?
I'm so disappointed that I'm looking which tablet should I buy and sell this one ... wrote to Xiaomi via email and via system bug report and no solution, it seems they really don't care for us - users of this tablet ...
Anyone with some "solution" out there?

I am using kodi + netflix plugin to force SDR streams
It takes some effort to set up and you lose some of netflix functionality (like downloads)
I think there's also similar plugins for other services (disney+, HBOmax, etc) but I have not personally tried them
It's a shame because xiaomi keeps marketing this device as Dolby Vision capable but we have to look for workarounds to disable this "feature"
Hopefully they will fix it if we provide enough reports, and now that the device got released in India it's expected to get more attention because it's a big market for Xiaomi

I'm also looking for this from weeks but no luck. We have to wait if Xiomi will fix this via update or we have to accept and start using as it is.
For the new tablet, you won't get any tablet in this price range which can beat mi tab 5 performance (except DV and HDR issue) if you want to wait then check realme tab having 870 processor and same specifications as mi pad 5.

Maybe new lenovo, but cost more

there is no fix for this, the screen is ips

Go to Advanced tools -> Video toolbox and add apps to video toolbox. Now when you open any added app, you will see a pill at top left corner. Drag it and select different styles of scenes. One of those styles disables HDR.

That's not true at all. There's not a single option that disables HDR, they only apply filters to the apps you chose. HDR is on a system level and it cannot be disabled at this moment.
Toolbox might help if you chose the "Outside" style, but still crap with black/dark content.

Yeah my thought exactly
People are saying this is an ips panel, display does not have enough brightness, etc.
Companies have been doing HDR on cheap displays for years
The ultimate goal of HDR is having better details in dark scenes.
You can still achieve this even if the display is ips or have average brightness, but you get the side effect of somewhat duller colors
But what I see on the Mi Pad 5 is definitely some kind of a software bug or miscalibration, because it does the exact opposite of HDR, it destroys scene details bright or dark
You can throw all the brightness in the world on this and it's not going to fix it

the problem is because the price, if you xiaomi change it with an amoled screen it will easily be 100$ more. your best bet is just sell your tab 5 now and buy a lenovo p11 pro with weaker processor but better screen.

and problems all the way, read their forums, it doesn't look good.

It is a SW issue. DV and HDR is fine with just player and mpv-android. It just doesn't work on streaming platforms.
It's also weird that people point out it's only 500 nits. Many laptop displays, ipads, imacs etc have "only" 500 nits too and they do HDR and DV fine (by fine I mean no black crush issues). So xiaomi just needs to fix it asap.

Question Whats wrong with A52s auto white balance

I would like to hear some opinions on this. I noticed some time ago that my videos had very inconsistent colors - there would be visible change of the balance when paning around or filming different objects to an extent that seems odd. After trying out and comparing I did realise that the main camera tends to very aggresively change the auto white balance, even if the scene is basically the same and the phone just slightly changes angle. It seems as it tries to desperately match white balance to every frame and its content (forgive my amateur vocabulary here), which to me seems strange and looking at other phones they just hold a much more consistent balance.
I attach 2 videos to show the issue - keep in mind that the issue isnt as visible always, as I tried very specific scenes/angles to show it.
When I use manual white balance it works great, so it kinda feels like a software issue (?)
Does anybody have a similar experience?

Would you mind trying to film a video in a similar scenario, but after disabling the option "scene optimizer" in the camera settings? I don't know if it does anything, but might be worth trying.

Thanks for the tipp, I'll try to compare it, although I dont think that scene optimizer affects videos

Unfortunately turning scene optimizer off doesnt change it (video attached).
It still feels like a software issue, but since nobody has yet confirmed a similar experience I'm starting to think it might be a problem with my unit. (Btw my A52s seems to have the Samsung image sensor not the Sony one)
Edit: or, I am exaggerating and this behaviour is actually not unusual - havent had a Samsung phone for a few years before my A52s

I do not shoot a lot of video, but in the few videos I did shoot I never saw what is visible in your videos (Sony sensor). It is indeed very jarring. Do you only have it with footage of grass or just always?
In the Samsung camera app, you can go the "Professional Video" mode in the "More" section (so where macro etc. is), and then set whitebalance manually to e.g. 5500K and see whether it is more stable then. But like I said I do not shoot a lot of video, so I certainly do not have experience with that professional video mode.
Edit: I now see that you already mention manual whitebalance yourself. So are there disadvantages to just using professional video mode all the time then?

It definitely gets more visible in outside scenes, more so if there is a lot of green in the frame - indoors and with artificial light it definitely is hard to spot. As I mentioned above it feels like it tries to match the balance to the content or objects of/in the frame, instead of keeping a consistent balance. I had a video where I stuck my hand in and out of the frame and it would drastically change the whole color to match the hand it seemed (thinking about it, the background was grass also, so ...).
Pro mode is a solution, it's just that I'm not a fan of setting the balance everytime I take a video or photo - and the balance ofc affects photos in the same way, as 2 photos of basically the same scene might have drastically different WB.
Nevertheless thanks a lot for your input - I also very much enjoyed your detailed instructions for Gcam usage

You would not have to set it every time (probably). In the Samsung camera app I have dragged the Pro Photo (not video) mode to the 'main bar' (from the more menu you can hold and drag items in and out of the main bar for quick access), with a changed fixed ISO (for shooting of fast action scenes), and you set it once and the camera app will remember that setting forever. And I think for all outside scenes around 5600K WB will work fine (it's not like the A52s is a high quality video machine anyway).
I didn't want to bring up gcam because I had no idea whether that would make a difference, but now that you brought it up, does that have the same whitebalance issues for you (in video)?

I meant I would have to set it again for every scene, but you are right, something like 5600 would probably be okay for most outdoor stuff. And with rearranging the icons it wouldnt be such a hassle. I'll try that out for daily use, thanks!
I am using BSG gcam also, because I find the nightmode drastically better but unfortunately the balance issue is the same, so I guess the balance gets set on system level. I also tried gcam awb but it always seems to be a bit off no matter the config - but I prefer the stock app for daylight anyway (apart from the wb)
