大视频文件转换使用ffmpeg

Question

I am using ffmpeg tool to convert videos from wmv to mp4 formats using the following code -

        string outputPath = args[1].ToString();
        string[] files = Directory.GetFiles(inputPath);               
        Console.WriteLine(files.Length);
        foreach (var item in files)
        {
            itemBkp = item;                                       
            Process proc = new Process();
            proc.StartInfo.FileName = @"e:\test\ffmpeg.exe";                   
            string filename= Path.GetFileName(item);                    
            proc.StartInfo.Arguments=  " -i "  + item + " " + outputPath + filename.Split('.')[0] + ".mp4";
            proc.StartInfo.UseShellExecute = false;
            proc.StartInfo.RedirectStandardInput = true;
            proc.StartInfo.RedirectStandardOutput = true;
            proc.Start();
            proc.WaitForExit();
        }

It works fine for videos up to 20mb but when i try for videos above 70mb it throws following error -

Is there a limit on video size to be converted?
