CBaseRenderer::Render
Microsoft DirectShow 9.0 |
CBaseRenderer::Render
The Render method renders a sample.
Syntax
virtual HRESULT Render( IMediaSample *pMediaSample );
Parameters
pMediaSample
Pointer to the sample's IMediaSample interface.
Return Value
Returns an HRESULT value. Possible values include those in the following table.
Value | Description |
S_FALSE | The filter is stopped, or pMediaSample is NULL. |
S_OK | Success. |
Remarks
This method calls the pure virtual method CBaseRenderer::DoRenderSample, which does the real work. The derived class must implement DoRenderSample.
Immediately before calling DoRenderSample, this method calls the CBaseRenderer::OnRenderStart method. Immediately after, it calls the CBaseRenderer::OnRenderEnd method. The derived class can override those two methods as needed.
Requirements
** Header:** Declared in Renbase.h; include Streams.h.
** Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
