Comment (by giwiniswut):
I am also affected by this issue. German TV station ZDF for example serves
their livestream with WebVTT subtitles served via HLS.
I found that there is a patch for X-TIMESTAMP-MAP support on
[https://patchwork.ffmpeg.org/project/ffmpeg/patch/20170205194344.333-1-franklinphillips@gmx.com/
patchwork.ffmpeg.org].
It is rather old (from 2017-02-05) but i changed it a little bit so that
it applies to the current master branch. I also made it so that it treats
all timestamps relative to the first fragment. See the attached patches.
