It did not compile anymore, so I did some qick fixes to update it to svn
head. I hope I did the porting correctly (I am not sure about the
configure and makefile parts).

Anyway, here is the ALSA input/output format... Apply the patch, and
copy alsa-audio.c in libavformat. Then, recompile and enjoy :)
Something like
./ffmpeg -f alsa -ac 2 -i writesomethinghere test.mp3
should work.

As you can see, the code is far from perfect (and some important parts
are not implemented yet). But it works (at least, it works for me :)...
To be clear: the code is not submitted for inclusion in svn, but if
someone wants to work on alsa, this is a good starting point.
