Generate a reference file:
{{{
./ffmpeg -f lavfi -i testsrc=s=720x480:d=400 ref.mkv
}}}
Mux DVD subtitles in:
{{{
./ffmpeg -i ref.mkv -i ~/fate-samples/sub/vobsub.idx -c copy -y test-
remux.mkv
}}}
Here, colors are fine (yellow foreground):
{{{
mpv --start=03:00 test-remux.mkv
mplayer -ss 00:03 test-remux.mkv
mplayer2 --ss=00:03 test-remux.mkv
}}}
Note: mpv¹ and vlc show this properly, mplayer and mplayer2 display them
in black & white (which is fine), ffplay seems to have various troubles.
Now encoding DVD subtitles in:
{{{
./ffmpeg -i ref.mkv -i ~/fate-samples/sub/vobsub.idx -c copy -c:s dvdsub
-y test-encode.mkv
}}}
Problem: the colors of the subtitles are negated (or shuffled dunno). They
also appear differently with players displaying them in black and white.
