title: Simple frame grabber from video file
body: <p>I would like to find simple lib for my C++ project which can start thread with video and audio decoding and I can grab some frames?
  I try to explain my expectations about lib API and behavior in sample code:</p>
  
  <pre><code>player = new Player("video.avi");
  player-&gt;Play();   // lib start video decoding into internal hidden buffer 
                    // and audio decoder start play sound from video file
  .....
  buffer = new ....
  player-&gt;SyncCopyCurrentFrameIntoBuffer(buffer);   // copy last decoded frame into buffer
  ....
  play-&gt;Pause();    // lib freeze video and audio decoding
  </code></pre>
  
  <p>May be somebody can recommend me something? (for Win)</p>
