command line - How to save video stream using VLC in commandline? -

i'm trying save online video using vlc in command line on window 7 basic.

here few things tried , worked partially:

i:\movies> vlc http://media.ch9.ms/ch9/7492/a92ae0a6-7b81-4114-b102aa055d147492/e2emeijerbrachadartmonadscontinuations.wmv --sout="#duplicate{dst=std{access=file,mux=wmv,dst='file.wmv'}, dst=display}" 

it plays video while streaming, , saves stream file.wmv. saved video doesn't have audio! command worked partially.

another try youtube:

i:\movies> vlc http://www.youtube.com/watch?v=tfr6g5zves8 --sout="#duplicate{dst=std{access=file,mux=wmv,dst='file.wmv'}, dst=display}" 

same result: saved video without audio. changed mux=wmv,dst='file.wmv' mux=webm,dst='file.webm' in command line, , ran again:

i:\movies> vlc http://www.youtube.com/watch?v=tfr6g5zves8 --sout="#duplicate{dst=std{access=file,mux=webm,dst='file.webm'}, dst=display}" 

it created file, neither video nor audio. again tried mux=mp4,dst='file.mp4'. same result : neither video nor audio, created file.

any idea how fix problem? missing?

as version of vlc i'm using, command vlc --version gives this:

vlc version 2.0.6 twoflower (2.0.6-7-g729aa7a) compiled fun on fat (apr  8 2013 23:22:26) compiler: gcc version 4.6.3 (gcc)  

-acodec , -vcodec

example:

"c:\program files\videolan\vlc\vlc.exe" -vvv dshow:// :dshow-vdev="usb video device" --sout=#transcode{vcodec=mp2v,fps=60,width=1080,acodec=mp2a,scale=1,channels=2,deinterlace,audio-sync}:standard{access-file,mux=ps,dst="c:\spi3-lite\videooutput\test1.mpg}
