• avformat/http: pass return code from http_open_cnx_internal() on its failure

  23 octobre 2014, par Andrey Utkin

  avformat/http: pass return code from http_open_cnx_internal() on its failure
  Previously, AVERROR(EIO) was returned on failure of
  
  http_open_cnx_internal(). Now the value is passed to upper level, thus
  
  it is possible to distinguish ECONNREFUSED, ETIMEDOUT, ENETUNREACH etc.

• HTTP Listener continuous data on same request (Keep alive)

  22 janvier 2019, par Kevin Jensen Petersen

  I’m currently trying to create a HTTP Server/Listener in C# which takes a Request and Keeps it open "Keep Alive" for further data being sent on a regular basis (FFMPEG streaming data), however I cannot seem to find an equivalent to what Node.js/JavaScript does in this example.

  I got the basics of HTTP Requests down and being able to "Keep it alive".

  Does anyone know of a way in C# ?

  var streamServer = http.createServer(function(request, response) {
  
  
  
      response.connection.setTimeout(0);
  
  
  
      request.on('data', function(data){
  
           socketServer.broadcast(data);
  
      });
  
  
  
  }).listen(STREAM_PORT);

• FFMPEG HTTP protocol closing after first packet

  27 août 2019, par rusty

  I’m trying to send a live video stream from my webcam to FFMPEG via the HTTP protocol. However after the first packet is sent FFMPEG closes, but does indeed output a fully playable video. As my intention.

  After going over the documentation for the protocol I thought mulitiple_requests would stop this behavior which it did not. After searching online for a few hours I can not find an example specific to my scenario. i.e. receiving a network stream over HTTP.

  Code running on the client-side :

  var xhttp=new XMLHttpRequest;
  
  
  
  if (navigator.mediaDevices) {
  
  
  
      var constraints = { audio: true, video: true };
  
  
  
      navigator.mediaDevices.getUserMedia(constraints)
  
        .then(function(stream) {
  
          var mediaRecorder = new MediaRecorder(stream);
  
          m = mediaRecorder;
  
          m.start();
  
          m.ondataavailable=e=>{
  
            xhttp.open("POST","http://localhost:8080");
  
            xhttp.send(e.data);
  
          }
  
          setInterval(function(){
  
            m.requestData();
  
          },2000);
  
        }).catch(function(error) {
  
          console.log(error.message);
  
        });
  
  }

  The FFMPEG command I have tried thus far :

  ffmpeg -listen 1 -multiple_requests -i http://localhost:8080 file.webm

  Maybe this is not possible with FFMPEG ? If this is the case then it appears the only solution would be to put this command in a loop and keep appending to the output.
