CBaseRenderer::GetCurrentSample

  • 项目

Retrieves the current sample waiting at the video renderer, or NULL if there is not one.

virtual IMediaSample *GetCurrentSample(void);

Parameters

None.

Return Values

Returns a pointer to the sample.

Remarks

The reference count for the sample is incremented before returning. This is so that if the sample comes due for rendering, it is not added back to the allocator free list until the caller of this member function releases it.

Requirements

DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
