  lavf/mpegts : drop a cargo-culted check
  This check has survived the transition to AVCodecParameters, but is no
  
  longer relevant after it, since the codec context is no longer updated
  
  or accessed at all from the demuxer.

• Browser MediaRecorder API - video controls not working / headers set incorrectly ?

  7 avril 2017, par leo

  I’m trying to record a webcam video in the browser and save the stream on a node server.

  Approach with MediaRecorder API

  // CLIENT
  
  // Init MediaRecorder with camera stream 
  
  recorder = new MediaRecorder(...)
  
  // Serialize data and send it to backend
  
  recorder.ondataavailable = (event) => {
  
     const reader = new FileReader();
  
     reader.readAsArrayBuffer(event.data);
  
     reader.onloadend = function (event) {
  
       socket.emit('message', reader.result);
  
     };
  
  }
  
  
  
  // BACKEND
  
  // Receive data and append it to the file
  
  client.on('message', (data) => { 
  
    fs.appendFileSync(filePath + fileName + videoFileExtension, data);
  
    ... 
  
  }

  Problem

  The first time the video is played in the browser the controls for forward and backwards are not working. Once it has been played, controls are ok.

  Assumption

  My assumption is that the headers are somehow broken.

  Question

  Any ideas how to repair the video captured by MediaRecorder and streamed to the NodeJS ? Or how to save the data chunks properly in a video file so that controls work ?
