p_sys from filter_t for a Audio - Modul

[Micha2223]

Hello,

Can someone help me with p_sys of filter_t, how can I use this Struct to creat data I need for all Frames?
Because i don't know how can i set a "float Pointer" to p_sys?
and get back it from there?

I found in filter_t the member p_sys from typ of filter_sys_t but i don't
found a document about filter_sys_t...

I looked in the the equalizer.c model for a solution but it doesn't works in my case und my
the vlc player fall down when i will start it.

Hope you can help me !!

Cheers
Micha
