I'm running the AI SDK on a ZCU104. I'm attempting to run the usb video input sample version from UG1354 (page 19).
The displayport output shows the correct Xilinx splash screen on boot and the facedetect program works perfectly when running the image only version.
However, when I run the command:
./test_video_face_detect_dense_box_640x360 0 -t 8
I get the following error:
VIDEOIO ERROR: V4L: device 0: Unable to query number of channels
I ran "ls -ltrh /dev/video*" and it shows both my usb webcam (video0) and hdmi camera (video1).
Both of these cameras I've used in other projects on the ZCU104 so I'm confident it's not a hardware issue.
Thanks!
