I would be very happy if devices were turned into lavfi sources and
sink. So if you're unable to make sarcasm that's actually relevant, next
time just shut up.

Anyway:

(1) It is not happening anytime soon, and blocking an immediate feature
for a distant refactoring is not acceptable in FFmpeg, only in avconv.

(2) the main advertised API for applications is not lavfi+movie, it is
lavf+lavc, so we have >15 years of applications written like that, and
we still need a mechanism to make filters and devices transparently
available in them.
