Hello Everyone, Right now. i am trying to stream raspberry pi camera from other jetson nano and on the other jetson nano to run darknet object detection. Is there a way to stream the video and run darknet on the other jetson nano for detection? Thank you ---

Hi, You can try to set up RTSP server on the Jetson Nano with raspberry pi camera. Please refer to > [@Jetson Nano FAQ](https://forums.developer.nvidia.com/t/jetson-nano-faq/82953): > > Q: What power supply should I use with Jetson Nano Developer Kit?

Please try with _videotestsrc_ plugin first to make sure it works. And then you can try the command like: ```auto $ ./test-launch "nvarguscamerasrc ! nvvidconv ! nvv4l2h264enc ! h264parse ! rtph264pay name=pay0 pt=96" ``` On the other Jetson Nano, you can run DeepStream SDK to receive/decode RTSP stream and do inferencing.

Hi DaneLLL Thank you for your kind assistance. I’m able to run the stream with the commands that you sent. It turns out, the stream has a delay for around 3 seconds. Is there any way to decrease the latency to perform a better inference on jetson nano? Thank you. ---

Hi, The latency may be from buffering in RTSP. You may try UDP and see if there is less latency. Please refer to test setup in [Gstreamer TCPserversink 2-3 seconds latency - #5 by DaneLLL](https://forums.developer.nvidia.com/t/gstreamer-tcpserversink-2-3-seconds-latency/183388/5) ---

Hi DaneLLL I did try UDP and it works well with latency around 500 milliseconds. Now, i’m trying to stream my pi camera video feeds but it always to show error like this: $ gst-launch-1.0 videotestsrc is-live=1 ! video/x-raw,width=1280,height=720 ! timeoverlay valignment=4 halignment=1 ! nvvidconv ! ‘nvarguscamerasrc ! video/x-raw(memory:NVMM),width=1280,height=720’ ! tee name=t ! nvv4l2h264enc insert-sps-pps=1 idrinterval=15 ! h264parse ! rtph264pay ! udpsink host=192.168.0.101 port=5000 sync=0 t. ! queue ! nvegltransform ! nveglglessink sync=0 (gst-launch-1.0:11878): GStreamer-CRITICAL \*\*: 11:45:04.360: gst\_element\_make\_from\_uri: assertion ‘gst\_uri\_is\_valid (uri)’ failed WARNING: erroneous pipeline: syntax error Is there a way to fix this? i’m new with nvidia jetson nano, so i’m really sorry if there’s a ridiculous error.

Hi, Please make sure `' '`, or `" "` is used, instead of `‘ ’`. Sometimes it is changed to `‘ ’` while copying gstreamer commands. Correct string should be ```auto ... ! "video/x-raw(memory:NVMM),width=1280,height=720" ! ... ``` or ```auto ... ! 'video/x-raw(memory:NVMM),width=1280,height=720' ! ... ``` ---

Hi, DaneLLL It Works! thank you so much. Now i’m trying to run darknet object detection on the other jetson nano. Is it possible to run darknet via UDP Stream? I think streaming udp is already part of the functionality of darknet, as in like to run something as: `./darknet detector demo data/voc.data cfg/yolo-voc.cfg yolo-voc.weights udp://@:5000` Or is there an actual way to perform the detection? Thanks ---

Hi, This probably needs other users to share experience. We are not sure whether the _darknet_ app supports UDP. ---
