title: C# extract frames from part of a video file
body: <p>Using AForge ffmpeg wrapper you can extract frames from a video using the VideoFileReader class and save it as a bitmap.</p>
  
  <p>See this for the exemple:
  <a href="https://stackoverflow.com/questions/17825677/extracting-frames-of-a-avi-file">Extracting frames of a .avi file</a></p>
  
  <p>My problem with that is that you cannot specified where to start reading the frames. It always starts from the beginning of the video file.</p>
  
  <p>But what if i wanted to extract frames that are in the middle of a two hours long video file. Using that class you'd have to parse the whole first hour juste to get to those frames.</p>
  
  <p>Does anyone know a way to achieve that?</p>
