DXGI_ERROR_UNSUPPORTED error when recording #220

Closed vincent1000 closed 1 year ago

vincent1000 commented 1 year ago

DXGI_ERROR_UNSUPPORTED error appears when I start to record on some machines. I am not sure whether this is related with cpus and graphics card, but both of these two machines have these same information: CPU: AMD Ryzen 7 5800H with Radeon Graphics Graphics card: NVIDIA GeForce RTX 3050.

My setting is as followed.

VideoEncoderOptions = new VideoEncoderOptions
                {
                    Framerate = 8,
                    IsFixedFramerate = false,
                    IsFragmentedMp4Enabled = false,
                    IsThrottlingDisabled = false,
                    IsHardwareEncodingEnabled = false,
                    IsLowLatencyEnabled = false,
                    IsMp4FastStartEnabled = false
                },

As these are laptops, I'm guessing it's related to a known bug with Windows and dual GPU's described here. If so, it should work using Windows Graphics Capture mode instead, or by forcing the program to use the dedicated GPU. I'll try to see if i can implement a way to force what GPU to use.
