• ffmpeg's "clev" and "slev" switches

  7 juin 2017, par Wally Walters

  Do the "-clev" and "-slev" switches have any effect on non-surround audio (e.g., mono and stereo) or are they safely ignored in the absence of the center and surround channels ?

• capture video conference between 1:1 user and broadcast to an rtmp url

  20 octobre 2020, par Asif Alamgir

  I am currently working on nodejs and socket app that is currently doing 1:1 video conference that is using webrtc. Videos are two separate element in the html and i would like to merge them together so that i can broadcast to rtmp url for public view (2:many). Is this possible

  


  For webrtc, i followed this tutorial https://www.youtube.com/watch?v=DvlyzDZDEq4, and for broadcasting i am using ffmpeg which current does 1 video stream.

  


  Please confirm if this is doable

  


  Update

  


  I was able to merge the video using
https://www.npmjs.com/package/video-stream-merger

  


  And now the final issue

  


  i am receiving merger.result which is merged stream and I tried to create a mediaRecorder object. Callback method for MediaRecorder ondataavailable is called only once but not every 250ms which i need to broadcast to youtube. How can i do this ?

  


  var merger = new VideoStreamMerger(v_opts);
...
...
merger.start()
myMediaRecorder = new MediaRecorder(merger.result);
myMediaRecorder.start(250);
myMediaRecorder.ondataavailable = function (e) {
    console.log("DataAvailable")
    //socket.emit("binarystream", e.data);
    state = "start";
    //chunks.push(e.data);
}
