CBaseRenderer::ClearPendingSample

  • 项目

Called to clear the pending sample when in a stopped or inactivated state.

virtual HRESULT ClearPendingSample(void);

Parameters

None.

Return Values

Returns an HRESULT value.

Remarks

This member function releases the IMediaSample interface. This allows the allocator to reuse it and allocate it to the upstream filter again. If the state is being changed to inactive, IMemAllocator::GetBuffer will return an error. This function also resets the current media sample to NULL to indicate that no data is now available.

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.
