Please don't top post. Well, indeed it's saying it doesn't support more than 2 *input* channels, so it's useless to force to 2 the number of output channels. At this point I don't know if it is possible at all to perform such resampling with ffmpeg (maybe with --enable-liba52?). Has someone any hints?
