This method provides support for forward and reverse scan modes.

Syntax

HRESULT Scan(
  BOOL bForward,
  double dRate,
  double* dwActual,
  DWORD* bVobuSkip
);

Parameters

  • bForward
    [in] The following table lists the values for the bForward parameter.

    Value Description

    TRUE

    Tells the renderer to scan forward.

    FALSE

    Tells the renderer to scan backward.
  • dRate
    [in] Rate range of greater than 1.0 to 400.
  • dwActual
    [out] Returns the actual rate that the driver can achieve given dRate.

  • bVobuSkip
    [out] The skip factor returned to the navigator.

    These values control how the navigator skips VOBU’s. This value must be in the range [0 – 15, 20, 60, 120, 240].  These ranges correspond to the FWDI and BWDI values found in table 4.5.4-1 (VOBU_SRI) of the official DVD Specification.  The next VOBU sent to the renderer will be approximately (0.5 x bVobuskip) seconds from the current VOBU.

Return Value

If the method completes successfully, the return value is S_OK.
