I’m attempting to streamline our approach to using the Gst-nvdsanalytics plugin. Currently, we are making extensive use of the feature. To my knowledge, there can only be one group of <roi-filtering-stream-n> per stream, which means that if I would like to apply one ROI to the first class and a different ROI to a different class on the same stream it has to be done in post-processing.

The implementation I have:

[roi-filtering-stream-0]
enable=1
roi-Person=0;0;0;1080;1920;1080
roi-Vehicle=0;0;1920;1080;1920;0
inverse-roi=0
class-id=-1

The implementation I would like:

[roi-filtering-stream-0]
enable=1
roi-Person=0;0;0;1080;1920;1080
inverse-roi=0
class-id=0

[roi-filtering-stream-0]
enable=1
roi-Vehicle=0;0;1920;1080;1920;0
inverse-roi=0
class-id=1

Would it be possible to implement something like this so that I can apply features per class?

No. Seems current nvdsanalyics can not support such case.

Thanks for getting back to me.
Will there be any support for this in the future?

[Fiona.Chen]

We will consider this request in future.
