2005,Wrong palette colors with DVD subtitles encoding,ubitux,,"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 03:00 test-remux.mkv
mplayer2 --ss=03:00 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.
