gf_vcap_set_input_dimensions()

Set video capture input dimensions

Synopsis:

#include <gf/gf.h>

void gf_vcap_set_input_dimensions (
        gf_vcap_t   vcap,
        int         width,
        int         height );

Arguments:

vcap: The handle of the video capture unit, returned by gf_vcap_attach().
width, height: The width and height of the captured frames, in pixels.

Library:

gf

Description:

This function sets a video capture unit's source dimensions. The source dimensions specify the size of the frames as they received by the video capture unit, prior to any cropping or scaling.

Changes made to a capture unit via the gf_vcap_set_*() set of functions are enqueued and do not take effect until you explicitly call gf_vcap_update().
