For filters, now that they use AVFrame and the complex buffer management API
is gone, it seems much more realistic. If someone were to try to work on it,
though, I would appreciate they contact me to discuss some of the points in
this mail:
It would be a waste to make public an API and deprecate it immediately.

Concerning the current issue, maybe add to vf_subtitles an API to read the
subtitles directly from a memory stream. That would still not be as good as
real support for subtitles in filters, but at least it is not too
ffplay-specific and could be used by other applications.
