.SH "FIELD DOCUMENTATION"
.PP 
.SS "\fBvo_frame_t\fP *(* vo_driver_s::alloc_frame)(\fBvo_driver_t\fP *self)"
.PP
Allocate an \fBvo_frame_t\fP struct, the driver must supply the copy, field and dispose functions 
.SS "void(* vo_driver_s::display_frame)(\fBvo_driver_t\fP *self, \fBvo_frame_t\fP *vo_img)"
.PP
Display a given frame 
.SS "void(* vo_driver_s::exit)(\fBvo_driver_t\fP *self)"
.PP
Leaving video driver. 
.SS "uint32_t(* vo_driver_s::get_capabilities)(\fBvo_driver_t\fP *self)"
.PP
Get capabilities of video driver. 
.PP
\fBSee also: \fP
.in +1c
