IDVDUserOperation::BackwardScan

  • 项目

This method performs scan play in reverse at the specified speed.

HRESULT BackwardScan(
  double dblSpeed
);

Parameters

  • dblSpeed
    [in] Scan speed multiplier. A value of 1 will cause play to resume at normal speed and a value of 0 will cause play to proceed by a single step. For other values of dblSpeed, the actual player behavior is dependent upon the capabilities of the renderer. If you specify a speed that the renderer does not explicitly support then the renderer will choose the closest speed that it does support.

If the function succeeds, the return value is S_OK.
