Multiple classification results

Hi all,

I ´m trying to achieve the same as described in this post. However, I have not succeeded.

I tried activating “output-tensor-meta=1” for the pgie but when iterating over user metadata structure (NvDsUserMeta) like it is done in pgie_pad_buffer_probe() function of quoted example, user metadata structure seems to be empty because the execution doesn´t go inside the loop.
