<a name="details" id="details"></a><h2 class="groupheader">Detailed Description</h2>
<div class="textblock"><p>According to the spec, when cues overlap, samples must be created.<br/>
The example below has 2 WebVTT cues:<br/>
00:01:00.000 &ndash;&gt; 00:02:00.000<br/>
hello<br/>
<br/>
00:01:15.000 &ndash;&gt; 00:02:15.000<br/>
how are you?<br/>
<br/>
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/>
start_time: 00:02:00.000<br/>
duration: 15 seconds<br/>
cue payload: how are you?<br/>
<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>
