Thank you for your help.
I got some insight looking at audiobargraph.c . In my other post, I have added some pseudo code on how I think a line should be drawn. I would appreciate it if you could take a look at it and tell me if I am going in the right direction.

Years ago we implemented the audiobargraph module that was drawing bargraphs representing audio levels on top of the video, it might give you some ideas.
PS: I am not sure this module is still working correctly...
