Issue with libvlc_video_set_callbacks

[fabsther]

I use this function :
https://www.videolan.org/developers/vlc ... 021d714bf0

I use it wrapped in C#.

The problem : I create 2 different instance of VLC, and also two different VLC Player , using two different VLc media.

Naturally I call libvlc_video_set_callbacks at start, setting up all I need.
At each time, calling libvlc_video_set_callbacks Stop activity from all previous callbakcs already set with libvlc_video_set_callbacks. If I achive to set them both at the almost exact same time it works fine, but it append 1 time over 4... I don't even need to play the second player to stop the first one, just setting up callbacks.
By the way, when i do that, the first player is still running, I still ear the sound and see the time moving...

What Can I do ?

I would guess that your wrapper is buggy then,

For anybody who could havce the same issue, I've just forgotten to pin in memory the callback, in the c# side. I assume that any new set of the callback using wrapping pin temporaly only the last callback used, than kto the marshaller.
