7.3.6. Sample Control Code
A Windows API function set is provided for controlling
the VPX. This API is independent of the actual used ver-
sion of the VPX. It is recommended to control the VPX
via this API, which allows flexible switching between dif-
ferent VPX family members. The API is available on re-
quest. The following code demontrates the usage of the
API to initialize the VPX.
#include <vpx.h>
// VPXAPI support header
VPXInit();
VPXSetVideoSource(VPX_VIN1, VPX_COMPOSITE);
VPXSetVideoWindow(VPX_VIDEO_WINDOW1, 23, 288, 0, 720, 720, 3000, 0);
VPXSetVideoWindow(VPX_VIDEO_WINDOW2, 0, 0, 0, 0, 0, 0, 0);
VPXSetVideoWindow(VPX_VBI_WINDOW, 320, 336, 7, 23, 0, 0, 0);
VPXSetVideoStandard(VPX_PAL);
VPXSetVBIMode(VPX_VBI_SLICED_DATA, VPX_VBI_ACTIVE);
VPXSetVideoAttribute(VPX_VIDEO_WINDOW1, VPX_CONTRAST, 128);
VPXSetVideoAttribute(VPX_VIDEO_WINDOW1, VPX_BRIGHTNESS, 128);
VPXSetVideoAttribute(VPX_VIDEO_WINDOW1, VPX_SATURATION, 128);
VPXSetVideoAttribute(VPX_VIDEO_WINDOW1, VPX_HUE, 128);
VPXSetVideoAttribute(VPX_VIDEO_WINDOW1, VPX_PEAKING, 128);
VPXSetVideoAttribute(VPX_VIDEO_WINDOW1, VPX_CORING, 128);
