Description
Step the transition to a certain offset. If the transition is set to real- time mode, it will step to the specified offset. If the transition is set to frame mode, it will ignore the offset and simply take the next step.
Parameters
  • pif
    [in]:
    Pointer to the ITransition2 interface object.
  • nOffset
    [in]:
    Specifies the new step offset.
  • pnStatus
    [out]:
    Used to track the state of the transition.

Return
   AEE_SUCCESS         :  The transition step successfully.

Comment
nStatus is set to ITransition2_STATUS_STEP_DONE if the transition has completed, otherwise it will be set to ITransition2_STATUS_STEP_MORE. The transition manager will use this status to determine whether or not the transition needs to be re- queued.
