Microsoft DirectX 8.1 (C++)

CBaseRenderer::OnReceiveFirstSample

The OnReceiveFirstSample method is called when the filter receives a sample while paused.

Syntax

virtual void OnReceiveFirstSample(
    IMediaSample *pMediaSample
);

Parameters

pMediaSample

Pointer to the sample's IMediaSample interface.

Remarks

The CBaseRenderer::Receive method calls this method. It does nothing in the base class, but the derived class can override it. This method is intended primarily for video renderers. When a video renderer is paused, it typically displays the first sample as a still image.

Seeking the graph while paused also causes this method to be called.
