Examples of combined audio video players?

Question

HTML

You need a player for combined audio / video lectures for the site (technology does not matter).
For example, a regular audio player, only in parallel with the audio is a slide show, as in a presentation.
Another example is a video player, only there is an additional window in which the slides switch at a certain time in parallel with the video.
Are there any examples of such players?
