rtsp url with aspect ratio?

[amcrest]

We're using vlc to view several rtsp camera streams. The rtsp urls all display properly, but one of them requires a manual adjustment to the aspect ratio in order to display properly, and we're wondering if the desired aspect ratio can be encoded into the rtsp url, please.

Initially. this connects:

Code: Select all

rtsp://user:passwd@192.168.1.10:4556/cam/realmonitor?channel=1&subtype=1

Then, one must manually enter Alt-va1 to change the aspect ratio to 16:9.

What is the syntax, if any, to encode the aspect ratio into the rtsp url?

Currently Debian 10, vlc 3.0.17.4 Vetinari

Thank you for your considerations.

It's possible if the server has such an option. VLC won't know or care what goes in the URL.
