• Transcode livestream on the fly and output to another server

  3 juillet 2014, par user2757842

  Currently I have my live stream transcoding and saving to a destination on my desktop, but what I would like is to transcode it and send it to another server.

  I create the outstream I would like my stream to go but it returns this error :

  events.js:72
  
          throw er; // Unhandled 'error' event
  
                ^
  
  Error: ENOENT, open 'C:\Users\Jay\workspace\FFMPEGtest\http:\192.168.201.237\LiveSmoothStreaming.isml\Streams(video)'

  Any help would be appreciated

  Here is my code :

  var ffmpeg = require('./index.js');
  
  var fs = require('fs');
  
  
  
  var outStream = fs.createWriteStream('http://192.168.201.237/LiveSmoothStreaming.isml/Streams(video)');
  
  
  
  //set the path to the live stream
  
  var proc = new ffmpeg({ source: 'rtmp://localhost/livepkgr/livestream live=1', nolog: true, timeout: 432000, inputlive:true})
  
  
  
      //set video bitrate
  
      .withVideoBitrate(1024)
  
  
  
      //set h264 preset
  
      //.addOption('preset', 'superfast')
  
  
  
      //set target codec
  
      .withVideoCodec('libx264')
  
  
  
      //set audio bitrate
  
      .withAudioBitrate('128k')
  
  
  
      //set audio codec
  
      //.withAudioCodec('libfaac')
  
  
  
      //set number of audio channels
  
      .withAudioChannels(2)
  
  
  
      .toFormat('ismv')
  
  
  
      .on('error', function(err, stdout, stderr) {
  
          console.log("ffmpeg stdout:\n" + stdout);
  
          console.log("ffmpeg stderr:\n" + stderr);
  
      })
  
  
  
      .on('end', function() {
  
          console.log('file has been converted successfully');
  
      })
  
  
  
      .on('error', function(err){
  
          console.log('an error happened: ' + err.message);
  
      })
  
  
  
      .writeToStream(outStream, { end: true}); // <-- Where I would like my stream to go
  
      //save to file
  
      //.saveToFile('C:/Users/Jay/Documents/movie/liveStream.ismv');

  8 juillet 2014, par harisK92

  I installed pulse00/ffmpeg-bundle

  and set it up like in documentation

  dubture_f_fmpeg:
  
      ffmpeg_binary:  C:\FFMPEG\bin\ffmpeg
  
      ffprobe_binary: C:\FFMPEG\bin\ffprobe

  But I got errors

  Unable to load FFProbe

      try { 
  
     }       return static::load($binaries, $logger, $configuration); 
  
     catch (BinaryDriverExecutableNotFound $e) { 
  
          throw new ExecutableNotFoundException('Unable to load FFProbe', $e->getCode(), $e); 
  
      } 
  
  }
