Description Jer Noble 2022-05-24 17:01:49 PDT

When a new cue is emitted from the parser that has the same contents and similar start time to an existing cue, it will be de-duplicated by dropping it. However, some encoders will split cues across WebVTT file boundaries and in this situation, valid cues are dropped.
