Option #2: If you cannot switch from the unresponsive app...

If you cannot switch from the unresponsive VLC app, press Command-Option-Shift-Esc for three seconds to force it to quit. This key combination tells OS X to force quit the frontmost app.

Option #3: Bash Terminal killall command option

Open the Terminal application and type the following killall command to kill the VLC app:

 
killall -9 {app-name}
killall -9 VLC
 

If you do not know the exact name of app, use ps command as follows:

 
ps aux
ps aux | grep -i vlc
ps -xu username
ps -xu vivek | grep -i vlc
