      Hi xiaoniu,
      Unfortunately I didn't implement the IMediaSeeking interface so I can't give you any advice on that.
      I would have a look at the source code of CTransformFilter, etc in the DirectShow base classes.
      Maybe you can find an example in there and then apply the concept to the case where there are two inputs?

      I'll have a look at that when I get a chance, let me know if you come right though.

    Sorry to resurrect an old thread, but I have the same question for the Picture in Picture filter.  My graph crashs when I try to seek the graph.  Am I right in thinking that this still hasn't been implemented?

    Cheers, Dave.

    Hi Dave,
    That's correct, it has not been implemented and we currently do not have any plans/resources to do so.

    Of course if you do implement it, we'd be more than happy to add it into the project :-)
