  public static class AVFormatContext extends Pointer {
  
      static { Loader.load(); }

  I’ve tried to run a java application with an FFMmpegFrameGrabber while trying to run on windows. However same jar file runs on linux with no exceptions.

  I have included javacpp and javacv jars .

  However while running on windows I am getting this error
  main" java.lang.NoClassDefFoundError : Could not initialize class org.bytedeco.javacpp.avutil"

• What is the "Error initializing filter 'drawtext' with args..." error in using of ffmpeg at c# process class ?

  7 novembre 2016, par parsa

  I used this below code for create a resolution of a video and write text on it.

      var proc = new System.Diagnostics.Process();
  
      strin OrginalResolution="nhd";
  
      proc.EnableRaisingEvents = false;
  
      proc.StartInfo.FileName = ffmpegPath;
  
      proc.StartInfo.Arguments = "-i \"" + fileIn +
  
                                 "\" -f mp4 -s " + OrginalResolution + " -vf drawtext=fontfile=/OtherProjects/ConvertProj/ff‌​mpeg/OpenSans-Reg‌​ular.ttf:text=Parsa" \"" + fileOut.Split('.')[0] +
  
                                 ".mp4";
  
      proc.StartInfo.UseShellExecute = false;
  
      proc.StartInfo.CreateNoWindow = false;
  
      proc.StartInfo.RedirectStandardOutput = true;
  
      proc.StartInfo.RedirectStandardError = true;
  
  
  
      proc.Start();
  
      proc.WaitForExit();
  
      string sdsd = proc.StandardError.ReadToEnd();
  
      proc.Close();

  I faced with this problem(some string output of StandardError is in below) :

  Fontconfig error: Cannot load default config file\r\n[Parsed_drawtext_0       
  
  @0000000002fd8c20] Cannot find a valid font for the family 
  
  Sans\r\n[AVFilterGraph @ 0000000000511660] Error initializing 
  
  filter'drawtext' with args 
  
  'fontfile=/OtherProjects/ConvertProj/ffmpeg/OpenSans-
  
  Regular.ttf:text=parsa'\r\nError opening 
  
  filters!\r\n

  In cmd the same argument value of process works fine.
  I read that this issue related to how to using quotation mark at using
  of text property of drawtext in ffmpeg.but I can’t find any
  solution for solving this issue.
  Can anyone help me ?

  Can anyone help me still ?Is this a bug ?
  I used any solutions for escape from : in my code,but can’t solve this problem.
  It can’t find font.I delete other filters of drawtext to findout that any of filters don’t mistake, but still error exists yet.

  expansion=none property of drawtext doesn’t influence on this case, for escape :.
