How to edit videos/pictures dynamically?

Question

JavaScript

Can you please tell me if it is possible to somehow dynamically change the content of a picture or video, that is, in fact, edit it?
For example, I added a video via input and I want to paste my logo on it. I would do it manually with a video editor.

If it is possible, then please give a vector of development, what to read.

Answer 1

On the back is ffmpeg and its overlay filter (see examples)
It's a non-instantaneous and little-parallel case (if 100 videos are thrown at once, there won't be enough resources for everyone), so you have to take care of the task queue.
