Hello,

I have downloaded and installed this ROS package. I was able to build the src with no issues, I also executed the make install command and that did not have any issues. However, when I run the package I see the following errors. Any advice or help is much appreciated. Thanks!

Looks like you forgot to source your environment.

The error says it's not finding the package video_stream_opencv. Also, did you modify the launch file with a video file of yours? Otherwise when you fix the first problem you'll get another error about that :)

If you are on indigo you can just install the package with apt-get. Kinetic is on its way, but not yet.

Thanks for the help. I am using Indigo on Ubuntu 14.04.

Sorry, I’m a bit of a novice with all of this, what would be the correct source command for this?

I did modify the launch file with an AVI file that I have on my desktop. What will be the error that I will receive with this when the first problem is corrected?

My overall end goal is to create a ros bag of the AVI file. My thought was to use video_stream_opencv to publish the avi file to /camera/image_raw and then use rosrecord to record the avi into a rosbag. Do you think that will work?

Thanks!

Hello. Install the package from apt-get and that error should disappear. (sudo apt-get install ros-indigo-video-stream-opencv). Then you can launch the launchfile you made. It should work. And then you should be able to do rosbag record /camera/image_raw to make a rosbag of the video as you pointed.

Thank you very much! That worked.
