Oak D lLite resolution and bandwidth

Raspberry Pi 4 can barely handle 1080p never mind 4k. Can you down convert the 4k stream? How does it work?

Hi @rlaferla,
you can downscale the 4K stream using the Image Signal Processor (ISP) the following way:

camRgb.setResolution(dai.ColorCameraProperties.SensorResolution.THE_4_K) # 3840 x 2160
camRgb.setIspScale(1, 3) # 1280 x 720

For more information about the setIspScale method, see the documentation here.
Is this what you meant by "down converting" the 4K stream"?
