• 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 ?

  avcodec/dca_parser : Extend DTS core sync word and fix existing check
  Check extended sync word for 16-bit LE and BE core streams to reduce
  
  probability of alias sync detection. Previously sync word extension was
  
  checked only for 14-bit streams (and this check did not properly work
  
  across buffer boundary).
  Use 64-bit parser state to make extended sync word detection work across
  
  buffer boundary.
  This is sufficient to make the sample in ticket #4492 parse
  
  successfully.
