• Merge Multiple Videos using node fluent ffmpeg

  8 juillet 2015, par shyamshyre

  requirement is to read all the files in the directory and merge them.
  I am using node fluent-ffmpeg to achieve this.
  First of all reading all the files in the directory appending concatenating the string by adding .input.

  var finalresult="E:/ETV/videos/finalresult.mp4"
  
  outputresult : It consists of all the files read in the directory.
  
  
  
  /*Javascript*/
  
  MergeVideo(outputresult);
  
  function MergeVideo(outputresult){
  
  console.log("in merge video");
  
  var videostring = "";
  
  
  
  for(i=1;i<5;i++)
  
      {
  
  videostring = videostring+".input("+"'"+outputresult[i]+"'"+")";
  
  }
  
  console.log("Video String"+videostring);
  
      var proc = ffmpeg()+videostring
  
      .on('end', function() {
  
        console.log('files have  succesfully Merged');
  
          })
  
      .on('error', function(err) {
  
        console.log('an error happened: ' + err.message);
  
      })
  
      .mergeToFile(finalresult);
  
  }

  It gives the following error :

  TypeError: Object .input('ETV 22-02-2015 1-02-25 AM.mp4').input('ETV 22-02-2015
  
  9-33-15 PM.mp4').input('ETV 22-02-2015 9-32-46 AM.mp4').input('ETV 22-02-2015 8-
  
  32-44 AM.mp4') has no method 'on'
  
      at MergeVideo (D:\Development\Node\node-fluent-ffmpeg-master\node-fluent-ffm

  Any help is appreciated.

• Recapping WebM’s First Week

  25 mai 2010, par noreply@blogger.com (John Luther) — webm, vp8, vorbis

  The WebM project launched last Wednesday with broad industry backing (watch video of the announcement). The list of supporters keeps growing with new additions such as the popular VLC media player, Miro Video Converter, HeyWatch cloud encoding platform, and videantis programmable processor platform. We’re also happy to see that future versions of IE will support playback of VP8 when the user has installed the codec.

  Our announcement sparked discussions in the community around the design and quality of our developer release. We’ve done extensive testing of VP8 and know that the codec can match or exceed the quality of other leading codecs. Starting this week, the engineers behind WebM will post frequently to this blog with details on how to make optimal use of its VP8 video codec and Vorbis audio codec. We are confident that the open development model will bring additional improvements that will further optimize WebM. In fact, the power of open development is already visible, with developers submitting patches and the folks at Flumotion enabling live streaming support in their product just three days after the project was launched.

  Keep an eye on this blog for regular updates on the adoption and development of WebM. To participate in the conversation or to ask questions of the WebM team, please join our discussion group.
