I'm a beginner with ROS, so i thank you in advance for your answers.

I have a file.bag (Video) available and I would like to publish the various frames on a specific topic at defined moments of time so that I can view this frame and work on it later. My question is how can I accomplish this in ROS Melodic with Python?

Thank you.

    $\begingroup$ Welcome to Robotics Stack Exchange! As you are getting started with ROS, I suggest using existing ROS packages to achieve this functionality. Following are the steps: 1) Export images from the bag file, 2) Select the frames you are interested in, and 3) Publish those frames/images one by one. $\endgroup$
