CLI conversion (Transcode / Upmux)

[smitht3]

Hi,

Please be gentle, my explanation and terminology might be dreadful here...

I am using VLC via CLI to convert file types and attributes.

CALL "C:\Program Files\VideoLAN\VLC\vlc" -I -vvv %1 --sout=#transcode{venc=ffmpeg,vcodec=mp1v,vb=1800,vt=0,fps=25,width=352,height=288,acodec=mpga,ab=224,samplerate=44100,channels=2,audio-sync,deinterlace}:standard{access="file",mux="mpeg1",dst="%_commanm%.mpg"} vlc://quit

The problem is when converting mono .AVI files, I lose the audio in WMP. Still works fine in VLC as you would expect.
I'm told it might be due to the encapsulation module or header?

Thanks
