IDVDRenderer::Scan (Windows Embedded CE 6.0)

1/6/2010

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.
