I’m the one who are using ros package named video_stream_opencv.
While I’m using it, I met a problem getting video stream from the device.
Here is my H/W Spec and situation.
-
Board : Jetson TX2
-
Device : Fushicai USBTV007 Video Grabber [EasyCAP]
-
rosdistro : ROS- Kinetic
-
OS : Ubuntu 16.04
-
OpenCV : 3.4.1 (replace 3.3.1-dev cv2.so with 3.4.1 cv2.so)
So I tried to get a video stream through the Easycap.
The ‘./test_video_resource.py’ works well at the moment at it shows video stream.
But when I use ‘webcam_launch’, if keep showing ‘VIDIOC_QUERYCTRL: Inappropriate ioctl for device’ error message.
So would you give me some advice to solve this problem?
