I've intentionally kept this initial version simple (no styling etc) to focus
on the basics. As this goes through review, additional features can be added
(I had initial PoC for styling implemented some time around previous VDD), and
there is another patch set in my queue which would then add support for muxing
TTML into MP4.
Changes from the sixth version:
- Split the lavc and lavf bits.
