I need a solution because I don't know how to start doing this. I need to create a short video analysis. Exactly the possibility of drawing on this video. So while playing the movie, I can stop it and draw, for example, lines. This line overlaps the film. It is IMPORTANT that, for example, a line that will be superimposed on the 20 second and erased at the 25 second of the film and saved. It is after the video has been played that after analysis, this line will appear in 20 seconds and disappear 25 seconds. Often it will be a slow motion movie so it's important that the lines do not jump over time.
I am looking for a solution on Xamarina, but if it is active, I will try to rewrite it. Maybe there are some libraries?
