could you tell us your specific use scenario？
- I need to access to image by cpu after inference. so nvnuf-memory-type-3 needed after streammux->nvinfer(server)
- I need to use streammux new
- Sadly, streammux-new always return nvbuf-memory-type=0 buffer (DeepStream 6.1 new streammux CUDA unified vs. default problem - #19 by Fiona.Chen). Thus nvvideoconvert need to change nvbuv-memory-type without changing resolution
