Source ID is always 0 for multi camera streaming

Accelerated Computing Intelligent Video Analytics DeepStream SDK

My application streamed 4 video cameras.
I am using deepstream-app.
Inside deepstream_app_main.c, all_bbox_generated function is used to get camera source id for each frame.

static void
all_bbox_generated (AppCtx * appCtx, GstBuffer * buf, NvDsBatchMeta * batch_meta, guint index)
{

}

static void
all_bbox_generated (AppCtx * appCtx, GstBuffer * buf, NvDsBatchMeta * batch_meta, guint index)
{  
  guint num_male = 0;
  guint num_female = 0;  
  for (NvDsMetaList * l_frame = batch_meta->frame_meta_list; l_frame != NULL; l_frame = l_frame->next) {
    NvDsFrameMeta *frame_meta = l_frame->data;
    guint stream_id = frame_meta->pad_index;
    for (NvDsMetaList * l_obj = frame_meta->obj_meta_list; l_obj != NULL; l_obj = l_obj->next) {
       
    }    
 }
}

Tested
guint stream_id = frame_meta->pad_index;
and
guint stream_id = frame_meta->source_id;

Both gives 0.
Why I can’t have different camera id there?

Hi,
Currently the latest release is r32.6.1(Jetpack 4.6) + DeepStream SDK 6.0. If there is no strong reason to stay on r32.4.3 + DeepStream SDK 5.1, we would suggest upgrade to latest release and try again.

Ok let me update and I’ll update again. Thanks
