• Download a stream via ffmpeg in Node.js

  16 juillet 2018, par loretoparisi

  I’m using ffmpeg to download an audio stream in Node.js. I use child_process for that :

  var downloadStream = function(uri,opath) {
  
      var self=this;
  
  
  
      // defaults
  
      var loglevel= self.logger.isDebug() ? 'debug' : 'warning';
  
      return new Promise((resolve, reject) => {
  
        const args = [
  
          '-y',
  
          '-loglevel', loglevel,
  
          '-v', 'quiet',
  
          '-i', uri,
  
          opath
  
        ];
  
        const opts = {
  
          cwd: self._options.tempDir
  
        };
  
        cp.spawn('ffmpeg', args, opts)
  
          .on('message', msg => self.logger.info(msg))
  
          .on('error', reject)
  
          .on('close', resolve)
  
          .on('exit', function (code, signal) {
  
            console.log('child process exited with ' +
  
                        `code ${code} and signal ${signal}`);
  
                        resolve(code);
  
          });
  
      });
  
    }//downloadStream

  What happens is that the close event is called before the file has been written to the disk. I have also registered the exit that is called with the close. While executing the command in bash I get the stream saved in the opath as expected. Which event listener shall I register for that ?

• downloaded a streaming video file from a website with ffmpeg in 1080p but i wanted to download in 720p as i have disk space limitations [on hold]

  22 octobre 2018, par C.J.

  I apologize if my language was unclear let me try to rephrase the question. I have downloaded a video from a video streaming website called "hotstar.com" with the help of ffmpeg. I extracted the m3u8 link from the site and was able to download it. The video is in 1080p video resolution which takes a lot of space. I want to download it in 720p resolution so that it would take less space. the code that i tried for it was this

  ffmpeg -i "https://hsprepack.akamaized.net/videos/hotstarint/world/kwks6/1_2/master.m3u8?hdnea=st=1540184067~exp=1540185867~acl=/*~hmac=a8945f016b594e1e2e4192ee05e2feaa5811c687d1891f69be1acc9057dd725f"
  
  -c copy output.mp4

  I hope I have asked properly this time. If not do tell me what is more needed.
