IAMExtTransport::SetBump

The SetBump method temporarily changes the playback, for synchronization of multiple external devices.

This method is not implemented.

Syntax

  HRESULT SetBump(
  long Speed,
  long Duration
);

Parameters

Speed

[in]  Specifies the temporary speed (a multiple of normal speed) as a long integer.

Duration

[in]  Specifies the duration of a bump as a long integer. The duration is given in the current time format; see IAMExtTransport::SetTransportBasicParameters for more information.

Return Values

Returns an HRESULT value that depends on the implementation of the interface.

Remarks

This method causes a temporary speed variation of the transport. The transport operates at the new speed until the specified duration elapses. Then it returns to its previous speed.

DV Implementation

MSDV does not support this method. It returns E_NOTIMPL.

Requirements

Header: Declared in Strmif.h; include Dshow.h.

Library: Use Strmiids.lib.
