Hello, I need to live stream my webcam, I want to have access to that stream from every PC in the same network - so I thought that UDP is the perfect solution for that. After some testing, reinstalling etc… I get that to work (I do not know if that work like UDP) : ./test-launch "v4l2src device=/…

Hi @Legion , I’ve given this a try and found it was working as expected. I can get about 350 ms latency with sync and about 150ms latency wiithout sync. For this, on jetson (NX), I ran: in a first terminal display a clock: while true; do date +%s.%N; done you may zoom in this terminal from men…

You may be confusing RTSP with RTP over UDP. test-launch will run a RSTP server. Not sure, but several clients may connect and read from it. With VLC, you would just provide the URI starting with rtsp:. Another way is using RTP/UDP with multicast address (you may check this ). In such case you woul…

Ok, the second solution worked and I can see the video on my PC! :D But it’s delayed like 2 seconds, can I somehow speed this up? PS: What if I want to play it in a different application or inside an OpenCV program on my PC how to do that, I can’t use .sdp file after all?

Hi, For UDP streaming, you may refer to [image] Jetson 4k Encoding -> Decoding Pipeline and latency Jetson Nano Hi, We can run 4K UDP streaming on two Jetson Nanos. One Nano runs two cases: videotestsrc gst-launch-1.0 videotestsrc is-live=1 ! 'video/x-raw,format=NV12,…

That doesn’t seem right? :/ I do not want to know my PC IP beforehand on Jetson, I want any PC to connect whenever.

I think most of the latency is due to VLC itself. You may ask to VLC users forum. Quickly tried some options as here but just reduced latency from 5s to 2s with still available options. From gstreamer receiver, you may try using rtpjitterbuffer that may try to adjust latency (in ms) sending upstrea…

Oh after trying that I get great improvement. Can I receive that stream any other way (other than VLC)- on Windows 10? I got some application from the client to test, but I can’t receive it thru it - I wonder is that my fault or application. So I would like to test it some other way I tried using …

You would try to specify the video capture backend. Seems ffmpeg is available, so you would specify: VideoCapture("udp://224.1.1.1:5000", cv::CAP_FFMPEG); Seems Windows Media Foundation backend is also available, but I have no experience with it. You may also have gstreamer installed on Win10, bu…

I tried with CAP_FFMPEG but get the same messages :<

I fixed that OpenCV issue with FFmpeg (some issues with Path and compilation mode), but I still can’t connect. .isOpened() returns false for me now. Do I specify something in the wrong way? After all, VLC has that .sdp file with some specification, maybe I need to pass them in OpenCV as well. Or m…

Sorry I missed that (I’m more familiar with gstreamer for such case). You would use the sdp file as well : setenv ("OPENCV_FFMPEG_CAPTURE_OPTIONS", "protocol_whitelist;file,rtp,udp", 1); cap = cv::VideoCapture("test.sdp", cv::CAP_FFMPEG);
