Hello everyone!

I am running an inference pipeline which resembles to deepstream-test-3 from NVIDIA-AI-IOT GitHub with DS 6.0 and i implemented a logic to restart the pipeline every time the camera changes stream.
My question is:
Can I somehow make the nvstreammux leave the output frame at the same height and width with the input one?
Or take the dimensions of the stream from the first element of the pipeline (source bin) which connects to the nvstreammux), so i can set the nvstreammux properties to them?
As the next element (nvinfer will make it the appropriate dimensions to be compatible with my model’s inference 640X640) i don’t want to perform another change at the nvstreammux, i think I do not need it and I loose information from the frame. What is your opinion on this?

Thanks a lot!

nvsterammux’ width and height are configurable. you can set to source’s dimension.

if nvinfer’s input resolution is not same with model 's input dimension. nvinfer will do scaling.

Sorry for the late reply, Is this still an DeepStream issue to support? Thanks! noticing you will restart the pipeline, you can set the width and height of nvstreammux before starting the pipeline.
