      <br>
      I am trying to write a pipeline which generates thumbnails of
      video files using pngenc.<br>
      <br>
      My pipeline runs without any error but the output png image is of
      0 bytes size i.e. nothing was written onto it.<br>
      <br>
      Below given is my pipeline:<br>
      <br>
      filesrc location=video.avi ! decodebin ! ffmpegcolorspace ! pngenc
      ! filesink location=video_thumb.png<br>

    this won't work. You are trying to produce one ng for every frame
    and send them to the same file. Take a look at the snapshot feature
    in playbin2/camerabin2.<br>
