That would require the search engine to be able to parse the media
formats, which I guess may increasingly be the case.

I was more thinking about the way in which a media resource works that
has captions inside it and that can expose them either as a separate
text file (which can then of course be indexed by a text-only search
engine), or multiplexed into the binary media file. If agree, if the
server doesn't do this, then the browser itself will need to do it to
expose it to screen readers - or search engines will need to do it
themselves.

As I said - there are experiments with ideas happening around captions. :)
