[joeyparrish]

Write a plugin for WebVTT in MP4.

i have a PR that implemented segmented webvtt. Maybe it is of some use to this project,

#291

[joeyparrish]

@kfwerf, #291 doesn't address the same feature.

#277 is about WebVTT embedded in MP4. #291 adds segmented WebVTT to v1 by parsing WebVTT cues.

We have already implemented segmented WebVTT in v2 (#150) and do not plan to backport to v1. v1 is in maintenance.

Please see the preview branch for the v2 work in progress. Thanks!
