VLC opencv video-filter-event in Python

[biga]

Hi!

I am new to VLC development, please help me.
I am planning to use VLC python bindings with opencv enabled. I found in the opencv_example.c source that it raises a video-filter event. I didn't find such an event type in vlc.EventType. How can I handle this event? I need it because the event contains an event_info structure where the detected face's positions stored, and I need them for further calculations to control servos.

Thanks for your replies.
