[vlc-devel] Re: RFC3016 (LATM) streaming

[PERET Pierre-Hugues]

I'm responding to myself.
It seems that the nigthly is not compiled with faac support.
Anyone can confirm ?
If yes , so i can use my windows to transcode files and the up them to the 
server, but i walk through the transcode from 2 to 1 channel pb.
any ideas ?

thx
