The CRendererPosPassThru class handles seek commands for renderer filters, by passing them upstream to the next filter.
This class derives from the CPosPassThru class. It adds support for caching the time stamps from samples as they arrive. Use this class in the same way as the CPosPassThru class. Refer to the CPosPassThru documentation for details.
The renderer filter must update the CRendererPosPassThru object's cached time stamps, as follows:
For an example of how to use this class, refer to the CBaseRenderer source code.
Header: Declared in Ctlutil.h; include Streams.h.
