Hello, This does not seem to be documented anywhere, and I have not been able to find any command line magic that does it. Either it's broken in 0.9.0 or it's really really well hidden. How to down mix (from stereo to mono) in the stream output chain in 0.9.0?? -- Rémi Denis-Courmont http://git.remlab.net/cgi-bin/gitweb.cgi?p=vlc-courmisch.git;a=summary
