How to make video playback auto stop at certain time points?

Question

Video

Hello.
The thought came to mind "what if, instead of a presentation in PowerPoint or Prezi, make a video and make it stop at certain time points and switch by pressing a key"
Actually the question is:
Are there any media players (preferably cross-platform, for example VLC) the ability to place "flags" on the time line and, so that when the time of this "flag" is reached, the playback stops?

Answer 1

no
