Stop Opera adding home directory to some links

A Former User

Hi!
I'm using Opera 53.0 in Fedora27. I would like to know how to prevent Opera adding home directory to web links. Not every one, but some.
So far any search has not resulted any valuable information.

Example:
I have link in web site:
rtsp://192.168.60.38:554/video.mp4 (link copied with right click: copy link address)
in html it is like:
<a href=" rtsp://192.168.60.38:554/video.mp4">Ovikamera</a>

When I clikck this link I get error splash window saying:

Error
/home/saku/rtsp://192.168.60.38:554/video.mp4 File or directory not found
OK

There are several orher pages that do the same effect adding "/home/saku/" to beginning of link and the saying that File can not be found.

How can I fix this?
It looks like some kind of mime problem, but where to tell Opera to use VLC?

Firefox and midori are working fine with this link opening the content in VLC.
