CRendererPosPassThru Class

CRendererPosPassThru Class Hierarchy

The CRendererPosPassThru class handles seek commands for renderer filters.

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.) In addition, however, the renderer filter must update the object's cached time stamps, as follows:

For an example of how to use this class, refer to the CBaseRenderer source code.

Requirements

Header: Declared in Ctlutil.h; include Streams.h.
