Ah, yes, of course.  I thought we were just discussing captions.

So are you proposing a single general utility function which you would
pass AVFrames, and it would perform changes to any side data that is
present (e.g. captions, MVs, etc)?  I had assumed we would introduce a
function specific to captions, which can be reused without having an
underlying AVFrame.
