CTransformOutputPin::m_pPosition member

  • Article

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

Helper object to pass seek commands upstream.

Syntax

IUnknown *m_pPosition;

Remarks

When the pin is first queried for the IMediaPosition or IMediaSeeking interface, it creates and aggregates a CPosPassThru helper object.
