Hi,
my pipeline is pgie->tracker->sgie(detector)->dsexample->sgie(classify). I use deepstream-app code, at sgie(classify) src pad, i use nvds_remove_obj_meta_from_frame to remove some object by object label but it does not work, it still show on the output frame although i see it jump to the remove function. Can you explain why it happen please ?
oh i found the difference, instead of using l_obj = l_obj->next in for loop, you try to use NvDsMetaList *obj_next = l_obj->next. I also try it and it worked, but could you explain why it worked please although the two way is almost the same .
