title: DirectShow : IMediaSeeking::SetRate not working with H.264 streams
body: <p>How can I set video playback rate when working with H.264 video streams with DirectShow?</p>
  
  <p>It looks like IMediaSeeking::SetRate dosen't work on H.264 video decoder. I tried the following decoders so far : Microsoft DTV-DVD Decoder (shipped with windows 7), FFDShow Video Decoder and Axis H.264 Decoder.</p>
  
  <p>Also, I noticed a DMO called Frame Rate Converter. Do you think it could help in this situation?</p>
  
  <p>Thank you.</p>
