I flash the JetPack2.3 on TX1 , then I install yolo detection( darknet) on TX1 . But I can’t run the demo because the OpenCV4tegra don’t support the camera, i change to OpenCV3.1 . but the demo of darknet capture nothing but black ,and the fps
is just 1.3? but i can run the yolo test

Hello, Keson:
if you are using opencv4tegra, you can use USB camera by opencv.
by opencv 3.1 and on-board camera, you need use GST pipeline, refer to https://devtalk.nvidia.com/default/topic/943129/jetson-tx1/highgui-error-v4l-v4l2-while-opening-camera-with-opencv4tegra-l4t-r24/post/4921383/#4921383
