I've been through the libavcodec directory with "grep -l CODEC_TYPE_AUDIO
mplayer-checkout-2007-08-10/libavcodec/* | xargs grep _encoder"

and come up with a whole list of audio codecs libavcodec supports (I've tested them too):

[already listed in man]
mp2
libmp3lame
ac3
adpcm_ima_wav
sonic

[not already in man]
vorbis
libfaac
flac
sonicls
wmav1
wmav2
{adpcm_adx}
adpcm_* (in adpcm.c)
pcm_* (in pcm.c)
g726
libamr_nb
libamr_wb
{libgsm}
{libgsm_ms}
roq_dpcm
------------------------------------

those in braces I can't get to work.
How many of these should go into the man/docs?
