使用python opencv实时接收webRTC视频流 [英] Receive webRTC video stream using python opencv in real-time

问题描述

我正在创建一个管道，需要在其中访问摄像机的数据并在其中执行一些opencv算法.我可以使用webRTC从源发送视频. https://lostechies.com/derickbailey/2014/03/13/build-a-local-webcam-with-webrtc-in-less-than-20-lines/

Hi,
I am creating a pipeline where I need to access data from camera and do some opencv algorithms in it . I am able to send the video from source using webRTC. https://lostechies.com/derickbailey/2014/03/13/build-a-local-webcam-with-webrtc-in-less-than-20-lines/

但是，我需要帮助的是如何在python中接收视频流并进行处理.如何从webRTC流向python后端访问视频提要?

But, What I need help is how to receive the video stream in python and do the processing. How can I access the video feed from an webRTC stream to python backend?

这是正在运行的javascript代码.

This is the javascript code running.

(function(){
  var mediaOptions = { audio: false, video: true };

  if (!navigator.getUserMedia) {
      navigator.getUserMedia = navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia || navigator.msGetUserMedia;
  }

  if (!navigator.getUserMedia){
    return alert('getUserMedia not supported in this browser.');
  }

  navigator.getUserMedia(mediaOptions, success, function(e) {
    console.log(e);
  });

  function success(stream){
    var video = document.querySelector("#player");
    video.src = window.URL.createObjectURL(stream);
  }
})();

在使用python从此Java脚本接收视频时，我需要帮助.

推荐答案

我是aiortc的作者.您是否已经查看了server示例，该示例说明了如何使用OpenCV处理视频?

I'm the author of aiortc. Have you checked out the server example, as it illustrates how to process video using OpenCV?
