| Microsoft DirectX 9.0 |
A new segment has started.
Parameters
lParam1
Pointer to a REFERENCE_TIME value that specifies the accumulated stream time since the start of the segment.
lParam2
DWORD value indicating the segment number (zero-based).
Default Action
This event is not sent to the application. Applications cannot override the default action for this event.
Remarks
If a filter will send an EC_END_OF_SEGMENT at the end of a segment, it sends this event at the start of the segment. The filter graph manager uses this event notification to compute how many EC_END_OF_SEGMENT notifications it should expect at the end of the segment.
By default, filters do not send EC_END_OF_SEGMENT events at the end of segments, and therefore should not send this event. For more information, see IMediaSeeking::SetPositions.
