Streaming webcam using rtsp protocol

[Róbert Ungurán]

Hi,
I'm trying to stream my webcam using rtsp protocol, but when I would like
to display the stream using vlc I'm receivin one or two frames and after
that I'm getting the following error messages:

vlc rtsp://localhost:8554/test

Where did I make the mistake(s)?
