I have been getting this error:
CS: ERROR: ioctl VIDIOC_REQBUFS failed at UsbCameraImpl.cpp:513: Device or resource busy (UsbUtil.cpp:156)
CS: WARNING: USB Camera 0: could not allocate buffers (UsbCameraImpl.cpp:514)
My camera code:
UsbCamera camera = CameraServer.getInstance().startAutomaticCapture(0); UsbCamera camera1 = CameraServer.getInstance().startAutomaticCapture(1); camera.setResolution(128, 96); camera1.setResolution(128, 96); camera1.setFPS(5); camera.setFPS(5);
It was previously working and then it simply quit and started giving the error. I have independently tried both cameras on both USB ports on the roborio.
