CMediaPosition Class

Microsoft DirectShow 9.0

CMediaPosition Class

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 Microsoft® 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.

Requirements

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

**  Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
