Would welcome comments on the second bit, whether the second patch
idea-wise is too bad for inclusion in upstream or not.

Additionally, I note that I've been way too focused on API-changing
changes with regards to library versions (major/minor), so while I
missed this during the TTML-in-mp4 muxing addition, would this sort of
a change be good to have a micro version bump for when applying?
