Hi,

I need help with mplayer ...

First, I'm trying to force mplayer to make its output in /dev/stdout ... 
I don't know how to do !! (i found a way but wit pcm audio output driver 
only)
Second, I want that the sound which is going to stdout is encoded as 
ALaw with a bitrate of 8000Hz / Mono. (This is for telephony applications)

I want to use mplayer because it can reads many streams format (MP3 
streams, WMA, ...). But I want that it outputs the audio to stdout as 
Alaw 8000Hz...

Does anybody know how to do it ?

What i got after a night of research  :

/usr/local/mplayer/bin/mplayer http://radionova.ovh.net:8000/ -format 
0x10 -af format=alaw,resample=8000:0:0,channels=1 -ao 
pcm:nowaveheader:file=/dev/stdout | ./cache
But it doesn't output alaw ! I think the driver "pcm" outputs PCM Audio 
datas ...


Thx for any response !

Guillaume
