CMediaPosition class

CMediaPosition Class Hierarchy

The CMediaPosition class handles the IDispatch methods of the IMediaPosition dual interface.

This class inherits the IMediaPosition interface but does not implement it. It implements IDispatch through the CBaseDispatch class and the DirectShow type library. Do not use this class directly. Instead, use one of the following classes:

  • Source filters: Use the CSourceSeeking base class to implement seeking.
  • Transform filters: Use the CPosPassThru class to pass seeking commands upstream.
  • Renderers: Use the CRendererPosPassThru class to pass seeking commands upstream.
