STYLE
::cue {
    font-family: Verdana, Arial, Tiresias;
    line-height: 125%;
}
::cue(.white) {
    color: #ffffff;
}
::cue(.lime) {
    color: #00ff00;

::cue(.bg_black) {
    background: rgba(0, 0, 0, 0.76);
}

sub0
00:00:07.120 --> 00:00:09.480 line:-1
<c.magenta.bg_black>Musique douce</c>

the output should be something like this i think

1
00:00:07,120 --> 00:00:09,480 
<font color=#ff00ff">Musique douce</font>

This because this file used VTT classes, So we should check if each line uses classes tags and removing it.
