[streaming] Which is the string for h263?

[Cavalera Claudio]

Hello,
I'm trying to transcode to H263 using VLC legacy interface on window.
 
My source is a live webcam:
dshow:// :dshow-vdev="Logitech QuickCam Express" :dshow-adev="none"
:dshow-size="" :no-dshow-config :no-dshow-tuner 
 
In the stream destination target of Stream output mask:
:sout=#transcode{vcodec=H263,vb=128,scale=1}:duplicate{dst=display}
 
I get:
ffmpeg error: cannot open encoder
stream_out_transcode error: cannot find encoder
main debug: unlocking module "rawvideo"
stream_out_transcode error: cannot create video chain
main error: cannot create packetizer output
What could be the problem?
I thought transcoding to H263 was supported.
I'm using VLC 0.8.1 on WinXP.



I also would like to know which string in command line represents h263
      --sout-transcode-venc <string>
                                 Video encoder

How can I know which strings i can put in <string> ?


Best Regards,
Claudio
