Extract sections from openCast

[Romern]

OpenCast videos can contain segments in

next(for m in ["search-results"]["result"]["mediapackage"]["metadata"]["catalog"] if m["type"] == "mpeg-7/text")["url"]

Example: https://gist.github.com/Romern/00939b6864b6c7fe2c450073ab713ada Extract all:

Description -> MultimediaContent -> Video -> TemporalDecomposition -> VideoSegment -> MediaTime -> MediaRelTimePoint

and add it to the mp4 if it supports segments or pack it into an mkv.

Similar information seem to be available in .vtt files which are also requested by javascript and seem to have a stable url
