Set the video capture source
#include <gf/gf.h> void gf_vcap_set_input_source ( gf_vcap_t vcap, int source_index );
gf
This function sets the video input source to a video capture unit. The value is a zero-based device-dependent index, which selects among multiple possible video sources.
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(). |
