I'm tracking several markers in an area of about 6m. Since I need to have control over the camera settings such as the image's brightness etc. I can not use a normal webcam and I am using a dslr camera with 4k resolution. Now I am trying to access the video stream in Unity using a capture card (Elgato HD 60). It seems Vuforia only recognizes the camera image if I send the signal as a virtual webcam to Unity. Unfortunately if I do so I have a dealy of about 0,5 seconds between the original video capture and the video stream in Unity/Vuforia.
Is there any way I can use a capture card directly in Vuforia to obtain a smooth performance? Is there any other capture card which is compatible to Vuforia? Or do you have any suggestion how I could receive a high quality video stream with controllable light settings?
Help is highly appreciated!!!
