IDvdControl2::SelectAngle method (strmif.h)

  • Article

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The SelectAngle method sets the new angle when the DVD Navigator is in an angle block.

Syntax

HRESULT SelectAngle(
  [in]  ULONG   ulAngle,
  [in]  DWORD   dwFlags,
  [out] IDvdCmd **ppCmd
);

Parameters

[in] ulAngle

Value of the new angle, which must be from 1 through 9.

[in] dwFlags

Bitwise OR of one or more flags from the DVD_CMD_FLAGS enumeration, specifying how to synchronize the command.

[out] ppCmd

Receives a pointer to an IDvdCmd object that can be used to synchronize DVD commands. The caller must release the interface. This parameter can be NULL. For more information, see Synchronizing DVD Commands.
