changing the marquee from the remote interface

[grndamgt4]

Hello, I have been using an older version of VLC on a security camera system for many years as I have custom data that is written as a marquee over the video feed.
The data changes based off of conditions of other devices in the security system. The hard drive crashed and I am having problems installing a vlc 2.0 version on the new ubuntu system due to dependencies.

In vlc 2.1 and later I cannot find a way to update the marquee over a live stream. Previously I was using the remote interface similar to below
echo "@marq marq-marquee mystring" | nc -U /tmp/vlc.sock

1) is there a way to periodically change the marquee over a live stream in a version later than 2.0?

2) Is there a way to use a package manager to install vlc 2.0 or earlier in ubuntu? I've also tried compiling from source but I have not been successful.

Thanks and happy new year.
