CBaseVideoRenderer::PreparePerformanceData (Compact 2013)

3/26/2014

Sets the m_trLate and m_trFrame values of the current frame.

Syntax

void PreparePerformanceData(
  int trLate,
  int trFrame
);

Parameters

• trLate
  How late the sample was beyond its due time, in reference time units.

• trFrame
  Interframe time, in reference time units.

Return Value

None.

Remarks

This member function sets m_trLate to the value of trLate and m_trFrame to the value of trFrame.

When the CBaseVideoRenderer::RecordFrameLateness member function is called from either CBaseVideoRenderer::OnRenderStart or CBaseVideoRenderer::OnDirectRender, it passes the values of m_trLate and m_trFrame for it to update the statistics.

PreparePerformanceData is called from CBaseVideoRenderer::OnWaitEnd to set these data member values.
