transcoding and streaming problems Linux

[yavlcfm]

i am trying to transcode an RTSP stream to MJPEG to display it in browser as picture
that's my code

vlc -vvv -Idummy rtsp://user:user@192.168.1.50:554/streaming/channels/2/preview #transcode{vcodec=MJPG,venc=ffmpeg{strict=1},fps=10,width=640,height=360}:standard{access=http,mux=mjpg,dst=http://192.168.1.99:8080}'

only the stream output is working
if I add --sout on the first line it is not working

upd: and the transcoding is working the only problem is to send the feed to url
