ffmpeg has a webvtt encoder and decoder already. You can use this command
to convert mpeg2 closed captions into webvtt:
ffmpeg -f lavfi -i 'movie=input.mpg[out0+subcc]' -map s out.vtt

> We are working on an IPTv project using FFMPEG.
> Now we stream Live TV channels in HLS format.
> We need to add Webvtt subtitles but as fare as I known Ffmpeg doesn't
> support it yet.
> We have make some lab test using CCExtractor + Home made Webvtt perl
> segmenter and it works but we are
> unable to sync subtitles with video/audio.
> We have seen that exists some Webvtt patch for FFMpeg but I don't know if
> this code works or not.
> Basically we need to get DVB Mpeg2 TS subtitles track and output it
> as webvtt hls directly with FFMpeg at same time as video / audios tracks.
> We are searching to hire a guy that can achieve this job for us.
