QM_SetTrackOffset

QM_SetTrackOffset(movieRef; trackID; trackOffset):error
	movieRef	Longint	Movie reference
	trackID	Longint	Track ID
	trackOffset	Longint	Track offset
	error	Longint	Error result

Changes the starting offset of a track. The track offset is the duration of the empty space at the beginning of the track. Changing the track's offset also affects the track's duration.

Parameter movieRef is the reference to the movie instance. The movie reference must have been previously obtained with a call to QM_NewMovieFromFile.

Parameter trackID is the ID of the track.

Parameter trackOffset specifies the track's offset and must be expressed in the movie's time scale.

Example

`Set the offset of track ID $trackID of movie $movie to 5 seconds

C_LONGINT($timeScale)
$error:=QM_GetTimeScale ($movieRef;$timeScale)

C_LONGINT($offset)
$offset:=$timeScale*5

$err:=QM_SetTrackOffset ($movie;$trackID;$offset)
