This has been driving me nuts. I have been recieving samples through Transform (I am using the CTransformFilter), but I want to buffer the data, then send it on downstream (after some filtering) when the filter is stopped. I buffer the data in my own structures, but I can''t seem to figure out how to send the data on when I am not supplied with a IMediaSample by the framework. I have tried using IMemAllocator from the downstream filter, tried storing the IMediaSample from the Transform (stupid I know)... If anyone can help that would be great.
