No frame data with External Display(Portrait)

[sharimken]

Thanks for the good tool of capturing displays. May I know if Display Orientation in Portrait supported? I tested few situation, but only Mac OS can return the correct result:

• Windows 11 Main Display(Portrait): return a cropped frame of portrait from "OnNewFrame", as the width and height remains the same of landscape mode. like a portrait frame masked by landscape frame, the missing part is black pixels.
• Windows 11 External Display(Portrait): nothing return from "OnNewFrame" or "OnFrameChanged", no callback at all.
• Ubuntu 21(Landscape): Get Frame Data, but all black pixels (maybe there is some permission issue?)
• Macbook Pro M1 Max External Display(Portrait): Correct Frame Data, Width and Height

i just moved to windows 11, so ill check if there are any issues with that. linux distros should work without issue. I dont have a real linux machine to test this on however. All of my tests have been in virtual box.

Unfortunately, you would have to debug these issues yourself :( Screen capturing can have some interesting side effects in ways that I have not encountered.

Id like to expand this library to capture these new scenarios, but it requires help from people like you since I dont have the same environment setup for testing

Awesome, glad to know that you have a chance to check the Win11 Portrait mode.

For Ubuntu testing, I tried installing all the required missing library and compiling the linux ".so" via CMake, with the default cmake commands "cd directory" -> "cmake ." -> "make". It looks fine since the ".so" does generate, but I am not 100% sure if it's correct or not. I can get the monitor width/height..etc. The Linux Frame pixels are always black.

Edit: My Dual Boot Ubuntu OS and Win11 are both running with Intel CPU, RTX 3060

If you have a testing app for Linux, I'd like to help to check and run the result.

I am able to reproduce the Win11 issue so i am trying to fix that now.

It does look like theres a win11 bug in the desktop duplication. I loaded Microsoft's official demo code and it fails in the same way.

Thanks for your updates.

Are you referring to this example for your Win11 test? I haven't tried their example yet, but hopefully they will fix it soon. or probably we should report the bug to them. https://github.com/microsoftarchive/msdn-code-gallery-microsoft/tree/master/Official%20Windows%20Platform%20Sample/DXGI%20desktop%20duplication%20sample

For Linux Platform, do you have testing example or compiled ".so" from your side? I still doubt about my cmake compile result, as it always return black pixels.
