How to activate Vout/Overlay option?

[tamiro44]

Hi everybody,
Does anyone knows how can i activate the text overlay option through code? (say C#)
I saw that with vlc 0.9.8a you can easily do it through original vlc gui.

Thanks,
Tamiro.

Currently, OSD is not available from Libvlc, except via the antique mediacontrol API.

Thanks Remi,
I'll be happy if you would give me a direction.
I've made a player (version 0.8.6i) written in C# and using libvl.dll.
How can i work with mediacontrol API?
Thanks,
Tamiro.

Personnaly, I don't know of any C# binding for mediacontrol.

And with C++?
How can i expose the appropriate functions in order to achieve my goal:
I want to extract "User Data" from RTP packets (using header extensions) and put it
on top of the movie.

With C (and C++) you can use the old mediacontrol API. The documentation is in the mediacontrol.h header file.

And display_text() allows me to display text on live video (RTSP/RTP)?
