How to fix these warning messages when running VLC player from command-line?

I installed VLC player on macOS using Homebrew, then when running it from command-line, I got many messages/warnings:

% which vlc
/usr/local/bin/vlc
% vlc
VLC media player 3.0.16 Vetinari (revision 3.0.16-0-g5e70837d8d)

...

And this:

% which cvlc
cvlc not found

Any idea how to fix them?

It turns out the syntax to run VLC play from command-line with an interface specification is to use the --intf (or -I) option:

vlc --intf <name_of_interface>

where the name of the interface can be chosen from the list given by

vlc -l | grep -iF interface
VLC media player 3.0.16 Vetinari (revision 3.0.16-0-g5e70837d8d)
18: macosx Mac OS X interface
21: ncurses Ncurses interface
127: oldrc Remote control interface
140: lua Command-line interface
144: lua Lua Playlist Parser Interface
160: dummy Dummy interface
202: motion motion control interface
353: hotkeys Hotkeys management interface
370: gestures Mouse gestures control interface

For example, to use no interface:

vlc -I dummy my_audio.mp3

To use textual interface is:

vlc -I lua my_audio.mp3

The fact

vlc my_audio.mp3

gives a warning that suggests 'cvlc' seems to be an obsolete command name.
