This page contains example code for Documentation:Format String.
This code is licenced under the Expat License (often called the MIT License)

This command-line example runs through format strings in the space /[$%][A-Z_a-z]/ as a test (or novelty). It should work for VLC 3.0.x under Windows or *nix, provided that vlc is the path to VLC

  • Windows users can change to the directory of VLC or replace vlc with "%PROGRAMFILES%\VideoLAN\VLC\vlc.exe"
  • macOS users can set a Bash variable or replace vlc with /Applications/

BigBuckBunny.ogv can be replaced with a video of your choice. The format strings cover the screen for three seconds, then VLC exits; invalid sequences will render as literal strings.

The code is written in the format X[$X] with X[] merely marking the code used to generate the rendered X. If you prefer:

vlc -I dummy '--sub-source=marq{marquee="$A $B $C $D $E $F $G $H $I $J $K $L $M $N $O $P $Q $R $S $T $U $V $W $X $Y $Z $a $b $c $d $e $f $g $h $i $j $k $l $m $n $o $p $q $r $s $t $u $v $w $x $y $z $_ %A %B %C %D %E %F %G %H %I %J %K %L %M %N %O %P %Q %R %S %T %U %V %W %X %Y %Z %_ %a %b %c %d %e %f %g %h %i %j %k %l %m %n %o %p %q %r %s %t %u %v %w %x %y %z",position=5}' --start-time=0 --stop-time=3 --no-video-title-show BigBuckBunny.ogv vlc://quit
