D3D11 ERROR: ID3D11Device::CreateTexture2D #280

Closed NotBadCoderr closed 8 months ago

NotBadCoderr commented 8 months ago

Hi! My computer has dual monitors. There is no issue when recording the primary screen, but an error occurs when trying to record the secondary screen. image

The error message seems to indicate an issue with BindFlags, and I have attempted to modify BindFlags=0. However, when attempting to CopyResource this time, another error occurs. image

secondary screen info

I believe the issue was that the texture was created on the ID3D11Device of the wrong monitor. Since you are recording from the outputs of two different video cards, there are also two ID3D11Devices, and textures have to be copied with the CPU between them. I pushed a fix with 805abff, let me know if it fixes the issue :)

Yes, it has been fixed. Thank you for your support.
