hello anupam.kumar, it shows fence timeout from the VI crash logs, let’s narrow down the issue, could you please refer to [Applications Using V4L2 IOCTL Directly](https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-325/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/jetson_xavier_camera_soft_archi.html#wwpID0EWHA), by using V4L2 IOCTL to verify basic camera functionality. thanks ---

Hi Jerry, it is not like that this command is not working…some times we are able to capture the video usng gst-launch command but some time it is giving error in nvargus-deamon and VI crash. can you please help here it is random behaviour. Also we are able to capture video using v4l2 command,v4l2 command is working properly we are able to capture raw image. ---

**There is no update from you for a period, assuming this is not an issue any more. Hence we are closing this topic. If need further support, please open a new one. Thanks** hello anupam.kumar, may I know what’s the failure rate? could you please try to enable camera stream with argus\_camera application, and enable ae\_lock to force exposure controls for verification. thanks ---
