From the deepstream pipeline, normally video stream will go through a primary detecter (gst-nvinfer), then to tracker (optional).
So, what if I installed several cameras to one Deepstream pipeline, but for different cameras, I want to use different models.
Is it possible in this way?
No. With nvstreammux, the multiple streams will be bundled into the batch, either PGIE or SGIE should work on batch but not single stream. If different streams need different models, please put them in different pipelines.
