  <blockquote>
    <p>If you already have image files the best way is using special
    "image2" format (FFMpeg demuxer) and FFMPeg will read files directly
    for producing video
        Video can be produced in real-time with live stream conversion supported by VideoConverter. In this case "rawvideo" should be
    specified as input format and C# application should pass RAW bitmap
    bytes (as mentioned in the question) as input for live stream
    converter.</p>

  <p>I try with this code but I always get video with 1 frame (the first one from array):</p>
  
  <pre><code>NReco.VideoConverter.FFMpegConverter c = new FFMpegConverter();
  
                  ConcatSettings set = new ConcatSettings();
                  set.VideoFrameRate = 5;
                  set.VideoFrameCount = 10;
                  set.ConcatVideoStream = true;
                  set.ConcatAudioStream = false;
                  set.SetVideoFrameSize(704, 576);
  
                   string[] _fileNames = new string[25];
                  _fileNames[0] = "g:\\Storage\\001.jpg";
                  _fileNames[1] = "g:\\Storage\\002.jpg";
                  _fileNames[2] = "g:\\Storage\\003.jpg";
                  _fileNames[3] = "g:\\Storage\\004.jpg";
                  _fileNames[4] = "g:\\Storage\\005.jpg";
                  _fileNames[5] = "g:\\Storage\\006.jpg";
                  _fileNames[6] = "g:\\Storage\\007.jpg";
                  _fileNames[7] = "g:\\Storage\\008.jpg";
                  _fileNames[8] = "g:\\Storage\\009.jpg";
                  _fileNames[9] = "g:\\Storage\\010.jpg";
  
             c.ConcatMedia(_fileNames, "g:\\Storage\\test2.mp4", Format.mp4, set);

  <p>I also try to use ConvertMedia() method instead ConcatMedia but with same result.</p>
  
  <p>Is there any way to tell converter this is a sequence of images ?</p>
  
  <p>Is there any other FFMPEG wrraper or way to do this ?</p>
  
  <p>I found AForge class which is good but working only with .NET 3.5</p>
  
  <p>Tnx!</p>
