Cannot connect to rtsp stream via vlc

Question

I have ip camera. When I go to this url

rtsp://192.168.20.100:554/user=admin&password=&channel=1&stream=0.sdp?

in my browser it offers me to use my standard video player and I can see the video. But when I try to open it in cvlc I have few errors

$cvlc rtsp://192.168.20.100:554/user=admin&password=&channel=1&stream=0.sdp?

I've found similar problem, but there isn't an answer

Convert RTSP stream to HTTP and stream it with VLC client

Solution

The rtsp url is quite uncommon specially with the ? at the end.

What occurs is that '&' character is evaluated by the shell, your command is truncked with the first '&' and some process are forked (the [7] 16585...)

It should work escaping '&' or quoting the url like this:

cvlc "rtsp://192.168.20.100:554/user=admin&password=&channel=1&stream=0.sdp?"

or

cvlc rtsp://192.168.20.100:554/user=admin\&password=\&channel=1\&stream=0.sdp?

The first one works. And it also works without ".sdp?" part. My bad, I just copied this url from old config file
