How do I implement forward/rewind based on key frame??

["Basil Dias" <basil.dias@wipro.com>]

I want to seek to the next/previous key frame in a movie file

using the IMediaSeeking interface of DirectShow.

 

I tried using the SetPositions call from this interface

with the AM_SEEKING_SeekToKeyFrame flag

along with all the positioning flags one by one.

I was trying this on an AVI file. But it didn't work.

It returns the Absolute position only.

 

Is there any other way if not this to do it?
