That was the only thing I could think of, but as far as I can tell there
*is* no way to configure libavcodec via MPlayer's configure script; I'd
inferred from that that MPlayer would simply compile *everything* in
libavcodec which it possibly could. If that isn't the case (which seems
likely, since there are parts of libavcodec I've never been able to get
to compile as part of FFmpeg), then how *does* one tell MPlayer which
parts of libavcodec to include and which to omit?

I've seen that reiterated numerous times over the past month or three,
and I can of course do that, but that isn't the real point. The point is
that this capability used to be available, but no longer is, even though
as far as I can tell I'm not doing anything different.

I try to compile in everything I can manage to, even down to
blinkenlights support despite the fact that the odds of my ever being
connected to the necessary hardware are ridiculously slim; even if it's
useless in practice, I want to have libavcodec's MP3 encoder available,
just on principle.
