I have not enabled this option when configuring ffmpeg.
I have made a copy of the wanted files (alsa-audio-enc.c, alsa-audio-dec.c,
alsa-audio-common, alsa-audio.h) in my version of ffmpeg in libavdevice. I
have made some modification so as to compil.
But I have forgotten to do something because, I can't find the format using
guess_format("alsa", NULL, NULL).
I have also made modifications in libavdevice/Makefile,
libavdevice/alldevices.c and configure.
