Adds a picture to a video track.

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 video track.

Parameters sampleTime and sampleDuration specify the insertion point and duration of the video sample. Both must be expressed in the movie's time scale. If sampleTime is -1, the video sample is added to the end of the track. In that case, parameter sampleTime also receives the actual time at which the sample was added.

Parameter pictSample is a picture variable.

Example

`Append a picture to video track ID $trackID

C_PICTURE($samplePict)
C_LONGINT($sampleTime;$sampleDuration)

$samplePict:=[Slides]Image
$sampleTime:=-1 `Append
$sampleDuration:=[Slides]Duration

$err:=QM_AddVideoMediaPicture ($movie;$trackID;$sampleTime;$sampleDuration;$samplePict)
