• ffmpeg installation on windows 8 xampp v3.2.1 php 5.5.3

  4 mai 2014, par user3454835

  I am trying to install ffmpeg extension on windows 8 xampp v3.2.1 for php 5.5.3.

  I have files of ffmpeg and i am doing following steps

  1. Placing file php_ffmpeg.dll in xampp/php/ext/
  2. Rest files i am keeping in windows/system32
  3. I have added extension=php_ffmpeg.dll in php.ini
  4. Restarted xampp

  but when i see php_info then my extension ffmpeg still not enabled.

  I think ffmpeg files are not compatible to php 5.5.3. May be i have old files so will you please provide me new and correct ffmpeg files for php 5.5.3

  or do you know why i am facing this problem ? any solution for this

• Running ffmpeg.exe through windows service fails to complete while dealing with large files

  28 avril 2013, par Harun

  I am using ffmpeg.exe to convert video files to flv format. For that purpose i use a windows service to run the conversion process in background. While trying to convert large files(i experienced it when the file size is >14MB) through windows service it gets stuck at the line which starts the process(ie, process.start();).

  But when i tried to execute ffmpeg.exe directly from command prompt it worked with out any problems.

  My code in windows service is as follows :

  private Thread WorkerThread; 
  
  protected override void OnStart(string[] args)
  
  { 
  
  
  
     WorkerThread = new Thread(new ThreadStart(StartHandlingVideo));
  
     WorkerThread.Start();
  
  }
  
  
  
  protected override void OnStop()
  
  { 
  
     WorkerThread.Abort();
  
  }
  
  
  
  private void StartHandlingVideo()
  
  {   
  
     FilArgs = string.Format("-i {0} -ar 22050 -qscale 1 {1}", InputFile, OutputFile);
  
     Process proc;
  
     proc = new Process();
  
  
  
     try
  
     {
  
  
  
       proc.StartInfo.FileName = spath + "\\ffmpeg\\ffmpeg.exe";
  
       proc.StartInfo.Arguments = FilArgs;
  
       proc.StartInfo.UseShellExecute = false;
  
       proc.StartInfo.CreateNoWindow = false;
  
       proc.StartInfo.RedirectStandardOutput = true;
  
       proc.StartInfo.RedirectStandardError = true;
  
  
  
       eventLog1.WriteEntry("Going to start process of convertion");
  
  
  
       proc.Start();
  
  
  
       string StdOutVideo = proc.StandardOutput.ReadToEnd();
  
       string StdErrVideo = proc.StandardError.ReadToEnd();
  
  
  
       eventLog1.WriteEntry("Convertion Successful");
  
       eventLog1.WriteEntry(StdErrVideo);               
  
   }
  
   catch (Exception ex)
  
   {
  
       eventLog1.WriteEntry("Convertion Failed");
  
       eventLog1.WriteEntry(ex.ToString());            
  
   }
  
   finally
  
   {
  
       proc.WaitForExit();
  
       proc.Close();
  
   }

  How can I get rid of this situation.

• 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
