Any idea why these subtitles appear black in my video? what's wrong with


Where can I find the specification of this standard for me to parse by
myself / debug / etc?

The command line I am using to add the subtitle is this:

ffmpeg \
-i video.m2t \
-i audio.aac \
*-i subtitle.sub \*
-vcodec copy \
-acodec copy \
*-scodec dvbsub \*
-metadata:s:a:0 language=por \
-metadata:s:s:0 language=por \
-map 0 -map 1 -map 2 \
-y out.ts
