Hi,
test_video_resource.py
to help debugging?video_stream_opencv
do you use? Could you run rosversion video_stream_opencv
and paste the result if you installed this package via apt-get
, otherwise roscd video_stream_opencv && git rev-parse HEAD
?No reply in almost a year, I'll close this issue, feel free to reopen it if there is any further info @furushchev @dohkim119 :)
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 anyone can give me some advice to solve this problem?
