Hi,
You may check the source code of gst_dsexample_transform_ip(). There is a for loop:
for (l_frame = batch_meta->frame_meta_list; l_frame != NULL;
l_frame = l_frame->next)
Probably you don’t need the loop in your case and can remove it. Since the default dsexample is for demonstration and reference, you would need to look at the code and customize it to fit your usecase.
