[Solved] True mono playback of live captured audio

[mark_orion]

I am using the following command line to play live captured video from a Hauppauge WinTV USB2 card:
vlc v4l2:///dev/video1:width=720:height=576:input=1 --input-slave=alsa://hw:2,0
Video and audio are fine except that the audio is only coming out of the right speaker.
Is there a way to tell VLC via command line to have real mono audio output (same signal on both speakers) ?

Solved it myself - this transcode did the trick:
vlc v4l2:///dev/video1:width=720:height=576:input=1:fps=25 --input-slave=alsa://hw:2,0 --sout '#transcode{acodec=mp3,ab=64,channels=1}:display'
