HI,

I just compile and run the imagine-camera example, using a USB camera. The fps is just 5, the picture in tutorial shows a figure of 29. Is the difference caused by the USB camera and onboard CSI camera? If I use a CSI camera (like the Raspberry Pi v2 camera), can I achieve the 2x FPS?

Thanks,

Hi ktktkt, yes it sounds to be limited by the camera USB data connection in this case. Is it a USB2 camera or USB3?

I’d recommend picking up a CSI camera if you want better streaming performance. Some USB3 cameras can also be better.

Thanks a lot. I think that is a cheap usb 2.0 webcam. Using default resolution 1280x720, fps=5, I reduce the resolution to 640x480, I get 15fps now.
