[vlc-devel] How to modify video output?

After implementing a stream_filter module, I have become a bit comfortable with vlc development environment.

Now, I have a new task. At a specific time during an mp4 media is being played, I need to draw a thumbnail image at a certain location over the underlying video image. The image should disappear after a few seconds. 

I am wondering what type of module do I need to develop.

I guess the concept is similar to displaying subtitles. Which module displays subtitles? Perhaps I can look at this module as an example.

Any other pointer is appreciated.

Thank you in advance for your help.
