IAMMultiMediaStream::OpenMoniker method (amstream.h)

  • Articolo

[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]

Note  This interface is deprecated. New applications should not use it.
 
The OpenMoniker method opens a file or device moniker; you can read media data from this moniker if DirectShow supports the moniker.

Syntax

HRESULT OpenMoniker(
  [in] IBindCtx *pCtx,
  [in] IMoniker *pMoniker,
  [in] DWORD    dwFlags

Pointer to the bind context associated with the moniker.
