What are vlc, qvlc, svlc, nvlc, rvlc, cvlc all for?

Having installed vlc version 3.0.18 on my RaspberryPi I see it provides all these possible ways to start it. So, what do they all do, I can't find anything that tells me.

When I run 'vlc' from an ssh login (the RaspberryPi is headless) I see:-

Code: Select all

chris@pimedia$ vlc VLC media player 3.0.18 Vetinari (revision 3.0.13-8-g41878ff4f2) [000000557b79b2b0] main interface error: no suitable interface module [000000557b6c6650] main libvlc error: interface "globalhotkeys,none" initialization failed [000000557b6c6650] main libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface.

VLC media player 3.0.18 Vetinari Command Line Interface initialized. Type `help' for help. >

But, strangely, if I run cvlc (which I thought was the way to get a command line interface), I see:-

Code: Select all

chris@pimedia$ cvlc VLC media player 3.0.18 Vetinari (revision 3.0.13-8-g41878ff4f2) [00000055cee96360] main interface error: no suitable interface module [00000055cedc1650] main libvlc error: interface "globalhotkeys,none" initialization failed [00000055cee96360] dummy interface: using the dummy interface module... [00000055cee5f910] main playlist: playlist is empty

Which is rather confusing!

They start a specific VLC interface
