Re: ioctl Errors and Intermediate Vision sample not working
We seem to be having the same issue.
We are just trying to initialize the USB camera (using Java) by doing this: camera = CameraServer.getInstance().startAutomaticCapture() and we are getting this: CS: ERROR: ioctl VIDIOC_S_EXT_CTRLS failed at UsbCameraProperty.cpp:66: Input/output error (UsbUtil.cpp:122) Exception in thread "NTListener" VideoException [edu.wpi.cscore.VideoException: property write failed] at edu.wpi.cscore.CameraServerJNI.setProperty(Native Method) at edu.wpi.cscore.VideoProperty.set(VideoProperty.jav a:68) at edu.wpi.first.wpilibj.CameraServer.lambda$new$1(Ca meraServer.java:498) at edu.wpi.first.wpilibj.CameraServer$$Lambda$2/3326003.apply(Unknown Source) CS: USB Camera 0: set FPS to 0 CS: ERROR: ioctl VIDIOC_S_EXT_CTRLS failed at UsbCameraProperty.cpp:66: Input/output error (UsbUtil.cpp:122) Exception in thread "NTListener" VideoException [edu.wpi.cscore.VideoException: property write failed] at edu.wpi.cscore.CameraServerJNI.setProperty(Native Method) at edu.wpi.cscore.VideoProperty.set(VideoProperty.jav a:68) at edu.wpi.first.wpilibj.CameraServer.lambda$new$1(Ca meraServer.java:498) at edu.wpi.first.wpilibj.CameraServer$$Lambda$2/3326003.apply(Unknown Source) CS: ERROR: ioctl VIDIOC_S_CTRL failed at UsbCameraProperty.cpp:72: Input/output error (UsbUtil.cpp:122) Exception in thread "NTListener" VideoException [edu.wpi.cscore.VideoException: property write failed] at edu.wpi.cscore.CameraServerJNI.setProperty(Native Method) at edu.wpi.cscore.VideoProperty.set(VideoProperty.jav a:68) at edu.wpi.first.wpilibj.CameraServer.lambda$new$1(Ca meraServer.java:498) at edu.wpi.first.wpilibj.CameraServer$$Lambda$2/3326003.apply(Unknown Source) |
