Do you mean that you want to send the frames with detections in it to another application?
I’ve been trying to do something similar and have managed to just drop frames when’re there is no detections. It’s seems to work fine when using the display or a file as a sink however I haven’t managed to get any other type of sink to work yet. ;-)
For me this is key for any IoT usage of deepstream and it doesn’t seem to be a use-case nvidia have thought about. Who wants an IoT camera that constantly streams - for me I only want streaming when there is something interesting to look at.
That’s not what I mean.
I want to use a broker subscription as SOURCE for the deepstream pipeline, because I have an image stream, that will not only be used by the deepstream pipeline, but also by other applications.
