• Acess to path is denied in ffmpeg conversion

  17 décembre 2013, par user1830062

  I have Windows 2008 R2 server, and am trying to convert my videos from any type to mp4 format. Everything is fine when running locally.

  However, when I try to do the same on the live web server, I am able to upload the file, but then when I try to convert the file, it says the file access is denied.

  Steps that I tried to sort but no clue pops the same server.

  1. changed the identity to network service /localhost
  2. gave full permission to the folder
  3. created virtual directory.
  4. impersonation is true.

  I have done all these things, but no response. One thing which I found was for eg :

  c:\inetpub\vhosts\mydomainname\httpdocs\myfolder_to save_uploaded_file

  which is readonly by default, I couldn't change them to all permission. Please advice how to change them to read/write.

  By the way, I am trying to save the converted file to

  c:\inetpub\vhosts\mydomainname\httpdocs\test_folder

• Error finding watermark path using ffmpeg in asp.net application

  27 août 2013, par irfanmcsd

  I am using .net ffmpeg wrapper to post watermark on videos. Posting watermark works fine if i execute ffmpeg command directly but failed to find suitable watermark png file location if command executed via asp.net application.

  here is sample ffmpeg command

  string RootPath = HttpContext.Current.Server.MapPath(HttpContext.Current.Request.ApplicationPath);
  
  _mhandler.FFMPEGPath = RootPath + "/ffmpeg_aug_2013/bin/ffmpeg.exe";
  
  _mhandler.InputPath = RootPath + "/contents/original";
  
  _mhandler.OutputPath = RootPath + "/contents/mp4";
  
  _mhandler.BackgroundProcessing = false;
  
  _mhandler.FileName = "wildlife.wmv";
  
  _mhandler.OutputFileName = "wildlife_ddd";
  
  string presetpath = RootPath + "/ffmpeg_aug_2013/presets/libx264-ipod640.ffpreset";
  
  _mhandler.OutputExtension = ".mp4";
  
  _mhandler.Parameters = "-s 640x380 -b:v 500k -bufsize 500k -b:a 128k -ar 44100 -c:v libx264 -vf \"movie = watermark.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:main_h-overlay_h-10 [out]\"";
  
  _mhandler.Parameters = _mhandler.Parameters + " -fpre \"" + presetpath + "\"";
  
  VideoInfo info =  _mhandler.Process();

  i tried direct code too

  string _out = "";
  
  Process _process = new Process();
  
  _process.StartInfo.UseShellExecute = false;
  
  _process.StartInfo.RedirectStandardInput = true;
  
  //_process.StartInfo.RedirectStandardOutput = true;
  
  _process.StartInfo.RedirectStandardError = true;
  
  _process.StartInfo.CreateNoWindow = true;
  
  _process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
  
  _process.StartInfo.FileName = _ffmpegpath;
  
  _process.StartInfo.Arguments = cmd;
  
  if (_process.Start())
  
  {             
  
      _process.WaitForExit(ExitProcess);
  
      _out = _process.StandardError.ReadToEnd();
  
      if (!_process.HasExited)
  
        _process.Kill();
  
  
  
      return _out;
  
   }

  Error on point ( Could find no file with path 'watermark.png' ) shows watermark.png file not found.
  I place watermark.png file in the following locations but still can't found

  i : application root

  ii : root where actual aspx page located

  iii : ffmpeg root

  iv : ffmpeg/bin/

  I also used complete path but still can't detected.

  Note : if i use same ffmpeg command in php and place watermark.png on location where actual php page exist watermark properly detected and command executed properly, but same approach not working in asp.net

  Can any one help me where should i place watermark.png file so that script can access it.

• Se passe de zpip-dist

  21 août 2013

  Il faudrait pouvoir se passe du plugin ^? zpip-dist.

  Il est dans les plugins obligatoires :

  
  zpip-dist ;svn ://zone.spip.org/spip-zone/_squelettes_/zpip-dist/trunk

  On devrait le surcharger complètement pour que mediaspip_core en soit indépendant et ne se basant que sur z-core.
