Hello folks, I have got the logitech C920 connected to the USB port on the pi zero streaming video to the jetson Nano. Using UDP. This works flawlessly and I am able to do image recognition, classification on the video that is streamed to the nano. Next, I checked the Lepton 3.5 connected to the …

hi @DaneLLL I got some help and finally got it to work perfectly. See attached for screenshot. This is what worked: ########################################################################### PIPELINES FOR LEPTON3.5/PURETHERMAL ###################################################################…

Also, the release version: R32 (release), REVISION: 4.4, GCID: 23942405, BOARD: t210ref, EABI: aarch64, DATE: Fri Oct 16 19:44:43 UTC 202

Hi, So the lepton/pure thermal is connected to USB port of raspberry pi zero, and you can successfully run the pipeline on Pi Zero: gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=UYVY ! videoscale ! videoconvert ! video/x-raw,format=I420,width=640, height=480,framerate=9/1 ! x264en…

[screenshot] Hi DaneLLL, See attached screenshot please. The window on the right is the Pi zero (SSH) Window on the left nano. The camera launches as you can see but it shows the redistribute latency … On the nano, you can see the output: (gst-launch-1.0:24007): GStreamer-CRITICAL **: 23:15:…

Hi, When copying the pipeline, 'application/x-rtp,encoding-name=H264,payload=96' becomes ‘application/x-rtp,encoding-name=H264,payload=96’ This leads to syntax error. Please correct the marks.

hmm, strange. So, I fixed that syntax and it took a little while, but for the first time I did see the video preview! I have hope now! I had to reboot the nano because there was no option to close the almost full size window. Video was super slow, but I’m just happy to see a stream. Should I try th…

Hi DaneLLL, This is what I used:(replaced the rtsp url from the example you quoted). It doesn’t work. See output attached. ########################################################### import cv2 import numpy as np cam=cv2.VideoCapture("rtspsrc location=rtsp://192.168.0.43:5000 ! rtph264depay ! h…

@DaneLLL The pipeline to launch camera on the pi as suggested by you yesterday that I tested and it worked, was using UDP The example you asked to try today on the nano to receive the stream is rtsp…wouldn’t this be an issue? Just so you know I am using this pipeline on the pi to launch the camer…

@DaneLLL If I use the udp source to capture the video streaming (using the modified version of what worked yesterday on nano CLI, then I get error: ###################################################### Using UDP source to recieve the video stream camSet= ‘udpsrc port=5000 ! ‘application/x-rtp,en…

Hi, Please ensure you can run the gst-launch-1.0 command: gst-launch-1.0 udpsrc port=5000 ! application/x-rtp,encoding-name=H264,payload=96 ! rtph264depay ! h264parse ! nvv4l2decoder enable-max-performance=1 ! nvvidconv ! video/x-raw,format=BGRx ! videoconvert ! video/x-raw,format=BGR ! fakesink I…

Hi,
You may try this python sample on Jetson Nano:
Doesn't work nvv4l2decoder for decoding RTSP in gstreamer + opencv - #3 by DaneLLL
Would need to modify the gstreamer pipeline in cv2.VideoCapture() accordingly.
