Why screen capture of youtube video turns out to be blank?

My Note was playing a video via the Youtube App. When I did a screen capture using the S-pen, the resulting image was a blank/black with the control keys. How come? Is this a bug?

Most likely copy protection, just like on Windows PC you won't be able ( in most scenarios ) to capture screen from any video player.

Maybe it depends on the video and copy protection, although I doubt it. Try taking a screen print with a palm swipe. It works for me. The only problem is trying to avoid the menu popping up.

Friend, I have replied to somewhat the same in here.
Hope this helps
And yes, you can capture screenshots using the above discussed techniques.

Video Playback

I downloaded my football teams app. And when I try to watch the videos they post of Press Conferences and other stuff. The video shows up pretty small and it gives me no option to make it full screen.
I just tested it on my S4 and it shows full screen in the same app.
Is there a setting that I don't have turned on to make all videos appear in full screen mode?

How to make YouTube app full screen without black bars

Is there a way to make video fit to screen with no black bars on each side when on full screen or landscape mode. My phone is currently rooted as well. Thanks

You may want to reword the thread as a question. It seems more like a statement that you have already figured this out. Just a thought.

I don't know if this works as i don't have recieved the phone yet, but try to copy the youtube link and paste it here.
stretch.site
It has sliders that let you chose your own aspect ratio. Maybe you can reach fullscreen in that way?

i think the only way you can do it is to root, install xposed, and make changes with per app settings. that should work i think

I currently download the youtube video with TubeMate, then open the clip with MX Player Pro or KMPlayer. In MX Player Pro it's possible to enable pintch to zoom, so you can over-zoom until there are no black bars visible. KMPlayer allows to zoom in a bit, which for some youtube videos is sufficient to remove all black bars, but not for the youtube videos that have black bars encoded in the video already.
Anyone successfully changed the Youtube DPI with an xposed DPI changer, to allow overzoom?

Because the aspect ratio is different, it won't happen natively. Like the other poster suggested, you need to zoom in the screen to chop off the top/bottom of the video.

just bumping this thread. Has anyone come up with a solution for per app? would love to be able to pinch-zoom native in the app.
Some apps like Netflix scale pretty damn well, most shows will take full advantage of the screen and movies will zoom to fit the width (leaving very narrow black bars), whereas youtube and iplayer leave these little black edges left and right... is a shame.

I just tried the latest guardians of the galaxy trailer and it played in full screen, i was trying to so what size that video is. Maybe new videos on YouTube are going to start being played in different ratios since the new up coming phones are 18.9

You can do it without root on every video on Youtube !
Just activate the "Magnification gesture" setting and then triple tap whenever you want to "zoom in" a Youtube video,it will still crop a little part of the video to make it full screen if the ratio is not the same though.

Native app feature from Youtube app version 12.44.54. Updated today and works fine.

So we no longer need Vanced?

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.

btw its hard to help or replicate when you provide 0 info on your testing enviroment....
like what player are you using?

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

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.

Question Black level of youtube videos

Hi all, i just tried my tab S8 and when playing videos on youtube app, the black level of video is good. But when i press any button on the keyboard cover, the black level on the videos changed become more grey/ white. I have to close the video, and reopen the video to have normal black level on the video again. Anyone know what happened and how to resolve it? Many thanks

I have this EXACT SAME ISSUE, but with the Sling app on my tab S8+. Whenever I open the app and start a video stream, the picture looks greyed out. I have to hit the home button to minimize the picture, which forces the app to resize the video without stopping the stream. That clears it up. Then I can maximize the video for full screen and there is no problem. However anytime I stop the video stream for whatever reason, like for example to resize the window or change the channel, the video opens up greyed out again and I have to go through this entire process all over again. I have not been able to find a solution to this problem. Don't mean to thread jack but I believe that the problem the OP has with the you tube black levels is exactly what is happening in the sling app. So perhaps whatever fix someone has for the OP's issue can be applied to my issue. Thanks.

I just checked that using usb keyboard and looks like this is an app interface bug. The app uses keyboard to navigate through interface. When you press a button it greys out element that is currently chosen. Apparently video player window is one big element, that's why it is being greyed out.
P.s. looks like it is possible to fix that by minimizing video player and pressing arrow keys

I haven't tried yet on the Tab S8 but on the Tab S6 I had the exact same thing happen when using an external BT keyboard / mouse combo, so I would assume this is some kind of Youtube app bug. I think you can also exit out of the video so it goes popup and go back in. I was using Youtube Vanced now that I think about it.
