.SH "DESCRIPTION"
.LP 
\fBMP4AddSceneTrack\fR adds a scene (aka BIFS) track to the mp4 file. MP4WriteSample() can then be used to add the desired BIFS commands to the track. The burden is currently on the calling application to understand BIFS.
.LP 
Those wishing to have a simple audio/video scene without understanding BIFS may wish to use MP4MakeIsmaCompliant() to create the minimal OD and BIFS information.
