I am not understanding how to run a video using ros_kinetic_kame. Please share me a video or complete process with all required packages that how to convert a .avi file into rosbag format.


Edit: This is my error I found :

$  roslaunch video_stream_opencv camera.launch video_stream_provider:="/home/test/Desktop/Prj/output.avi"

Yes, it is possible. Can you please tell us what have you tried and what didn't work exactly. As a start you can use video_stream_opencv, video_player is outdated.

How to get the video_stream_opencv I have tries to get its packages but all I find the error for broken packages only

I've posted an answer for your first question that should work once the package is installed correctly. Can you please share the dependency errors that you've got to help you solve them.

Jasmin gravatar image Jasmin  ( 2019-03-07 02:36:14 -0500 )edit

did you use sudo apt-get install ros-kinetic-video-stream-opencv to install the package or install it from source?

I've used video_stream_opencv once with ROS indigo,

Installed it with sudo apt-get install ros-indigo-video-stream-opencv

And run it on an .avi video as follows:

#check if the input video is fine:
$ rosrun video_stream_opencv test_video_resource.py path_to_your_video/your_video.avi
#run it:
$ roslaunch video_stream_opencv camera.launch video_stream_provider:="path_to_your_video/your_video.avi"

The output topic is /camera/image_raw, note that you may need to adjust some parameters if needed (fps, frame_id...)

Once you have your topic ready you can record a bag of your video data directly with rosbag record

If your need is images published to a ROS topic, we are already there!

But if you just need the bag file and want a more direct conversion you may make use of this link and this question's answer.

After executing $ rosrun video_stream_opencv test_video_resource.py home/Desktop/Prj/output.avi Error: Trying to open resource: home/Desktop/Prj/output.avi Error opening resource: home/Desktop/Prj/output.avi Maybe opencv VideoCapture can't open it

Please tell me the process to execute this code with ROS. Does it need video_stream_opencv?

Check the path to your video file again, I think that the user name is missing, it should be something like /home/user_name/Desktop/...

$ roslaunch video_stream_opencv camera.launch video_stream_provider:="path_to_your_video/your_video.avi" To launch this command roscore opened in another tab is required?

SUBHASH gravatar image SUBHASH  ( 2019-03-07 04:07:13 -0500 )edit

It should run roscore automatically... Maybe, I'm not sure in this case. Did it work only when having a running roscore?

This worked properly: rosrun video_stream_opencv test_video_resource.py path_to_your_video/your_video.avi Now I want to convert my .avi file to .bag file How to do that? $ roslaunch video_stream_opencv camera.launch video_stream_provider:="path_to_your_video/your_video.avi" above command gave me err
