• using node-fluent-ffmpeg to transcode with ffmpeg on windows not working

  25 juillet 2015, par jansmolders86

  I’m trying to use the module node-fluent-ffmpeg (https://github.com/schaermu/node-fluent-ffmpeg) to transcode and stream a videofile. Since I’m on a Windows machine, I first downloaded FFMpeg from the official site (http://ffmpeg.zeranoe.com/builds/). Then I extracted the files in the folder C :/FFmpeg and added the path to the system path (to the bin folder to be precise). I checked if FFmpeg worked by typing in the command prompt : ffmpeg -version. And it gave a successful response.

  After that I went ahead and copied/altered the following code from the module (https://github.com/schaermu/node-fluent-ffmpeg/blob/master/examples/express-stream.js) :

  app.get('/video/:filename', function(req, res) {
  
  res.contentType('avi');
  
  console.log('Setting up stream')
  
  
  
  var stream = 'c:/temp/' + req.params.filename
  
  var proc = new ffmpeg({ source: configfileResults.moviepath + req.params.filename, nolog: true, timeout: 120, })
  
      .usingPreset('divx')
  
      .withAspect('4:3')
  
      .withSize('640x480')
  
      .writeToStream(res, function(retcode, error){
  
          if (!error){
  
              console.log('file has been converted succesfully',retcode);
  
          }else{
  
              console.log('file conversion error',error);
  
          }
  
      });
  
  });

  I’ve properly setup the client with flowplayer and tried to get it running but
  nothing happens. I checked the console and it said :

  file conversion error timeout

  After that I increased the timeout but somehow, It only starts when I reload the page. But of course immediately stops because of the page reload. Do I need to make a separate node server just for the transcoding of files ? Or is there some sort of event I need to trigger ?

  I’m probably missing something simple but I can’t seem to get it to work.
  Hopefully someone can point out what I’ve missed.

  Thanks

• php_ffmpeg module not loading in Windows 7

  28 mars 2014, par Warwick

  PLEASE help me ! I have been searching for solutions for days !

  I am running Apache 2.2.22 and PHP 5.3.21 on Windows 7.

  I have extracted and copied php_ffmpeg.dll to C :\Program Files (x86)\PHP\ext ; copied avcodex-51.dll, avformat-51.dll, avutil-49.dll and pthreadGC2.dll to C :\Windows\System32 ; and added the extension=php_ffmpeg.dll directive to php.ini. However, the module is still not loading.

  I found the following error in the PHP error log :

  PHP Warning :  PHP Startup : Unable to load dynamic library 'C :\Program Files (x86)\PHP\ext\php_ffmpeg.dll' - The specified module could not be found.

  Any help would be dearly appreciated !

• trim MULTIPLE .mp4 files using ffmpeg in WINDOWS DOS

  22 février 2014, par user1530322

  My goal is to trim the first 4 seconds of, say 100 .mp4 files at once.

  I can easyly do it and in a quite quick way for one single .mp4 file at a time using :

  **ffmpeg -i MYFILE.mp4 -ss 00:00:04.000 -c:v copy -c:a copy Trimmed_MYFILE.**mp4

  I have a folder with those 100 mp4 files and want to bulk trim the first 4 seconds and save the new files on a folder in the same location called "newfiles".

  I'm imagining something like a loop, using FOR or so, but have no ideia how to do it.

  Thank you in advanced
