These are added (AddSample()) as 2 samples but must be split into 3 samples and 4 cues ('vttc' boxes).< br / >
First sample:< br / >
start_time: 00:01:00.000< br / >
duration: 15 seconds< br / >
cue payload: hello< br / >
< br / >
Second sample:< br / >
start_time: 00:01:15.000< br / >
duration: 45 seconds< br / >
cue payload: hello< br / >
cue payload: how are you?< br / >
< br / >
Third sample:< br / >

This class buffers the samples that are passed to AddSample() and creates more samples as necessary. Methods are virtual only for mocking, not intended for inheritance. < / p >
