GStreamer with WebRTC, OpenCV-Server-Client

Question

I don't know if I can say “I'm sorry for ask” but I spent more than a week looking for a solution without success. I have a Jetson Nano and with OpenCV I get and process an image at 4fps, I need to send this video to a web server to allow the client connected to the server get the video. Everything need to be written in C++. Because a need a low latency I did test with GStreamer and WebRTC without success. I don't have any web server ready, so I can use any implementation.

Anyone know where I can find some example implementation with this schema?

Answer 1

You can use mediasoup to send data to the server to then send the stream with rtp to another endpoint like gstreamer or ffmpeg.

Here is a recording project where data is sent from the browser -> server -> gstreamer -> file.

Mediasoup is written in c++ and has a wrapper for js.

Answer 2

I had similar problem and used such example from GStreamer WebRTC official repo. It's written in Python for Janus Gateway video rooms but I think it can be easily rewritten in C++ as you need.

In the code for OpenCV, I used V4L2Loopback as a virtual output device to be used as input for GStreamer WebRTC example.

I hope such approach may help you.
