IAMTimelineSrc::FixMediaTimes

The FixMediaTimes method rounds the specified time values to the nearest frame boundary, as defined by the output frame rate. In general, applications do not need to call this method.

Syntax

  HRESULT FixMediaTimes(
    REFERENCE_TIME *pStart,
    REFERENCE_TIME *pStop
);

Parameters

pStart

Pointer to a variable that contains the start time, in 100-nanosecond units. If the call succeeds, this variable is set to the rounded time.

pStop

Pointer to a variable that contains the stop time, in 100-nanosecond units. If the call succeeds, this variable is set to the rounded time.

Return Value

Returns S_OK if successful, or E_POINTER otherwise.

Remarks

This method is similar to the IAMTimelineObj::FixTimes method, but it preserves the original ratio of media times and timeline times. Just rounding the times to the nearest frame boundary could distort this ratio.
