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 As a start you can use video_stream_opencv, video_player is outdated.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 ( 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/...

Jasmin ( 2019-03-07 03:56:34 -0500 )edit

$ 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 ( 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?

I got this error: $ roslaunch video_stream_opencv camera.launch video_stream_provider:="/hometest/Desktop/Prj/output.avi" ... logging to /home/test/.ros/log/98df6008-40c1-11e9-9e42-c81f6622f107/roslaunch-DH1CT5Z1-14432.log Checking log directory for disk usage.

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

SUBHASH ( 2019-03-07 04:44:36 -0500 )edit

what kind of error, can you post it here?

Jasmin ( 2019-03-07 04:49:00 -0500 )edit

This is not an error, it means that everything is working fine :). Can you tell me if you are able to visualize your video frames when running rosrun image_view image_view image:=/camera/image_raw in a new terminal just after running the previous command.

Jasmin ( 2019-03-07 05:04:13 -0500 )edit

Sorry I've just seen your answer containing the output messages. don't add them as answer you can edit your question to add them. did it say at some point [ERROR]... Failed to contact master at [localhost:11311]. Retrying... did you try running roscore first then camera.launch ?

Jasmin ( 2019-03-07 05:21:17 -0500 )edit

$ rosrun image_view image_view image:=/camera/image_raw This worked I can see my video but now how to convert it into .bag format?

SUBHASH ( 2019-03-07 05:21:33 -0500 )edit

great! you can use rosbag record for that as mentioned in my answer.

Jasmin ( 2019-03-07 05:27:45 -0500 )edit

I got this error while recording on tab of $ roslaunch video_stream_opencv camera.launch video_stream_provider:="/home/test/Desktop/Prj/output.avi" this command: OpenCV Error: Assertion failed (key_ != -1 && "Can't fetch data from terminated TLS container.") in getData, file /tmp/binarydeb/ros-kinetic-opencv3-3.3.1/modules/core/src/system.cpp, line 1532 terminate called after throwing an instance of 'cv::Exception'

SUBHASH ( 2019-03-07 05:46:33 -0500 )edit

But .bag file also created. Now how to see whether recorded video is the same or not?

SUBHASH ( 2019-03-07 05:49:01 -0500 )edit

rosrun image_view image_view image:=/camera/image_raw and rosbag play your_bag.bag
