Set the video device synchronization values
#include <gf/gf.h> void gf_vcap_set_sync_values ( gf_vcap_t vcap, int h_offset, int v_offset, int h_total, int v_total );
gf
This function specifies device-dependant values to allow the captured image to be synchronized and centered properly. These settings have no effect on many devices, and do not always need to be supplied.
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(). |
