I've tried all the above options without success..

This code I use both on my PC and my server, works perfectly, the sub file should be .ass format (use aegisub or even ffmpeg to convert your sub to it)

ffmpeg -loglevel 16 -i input.mp4 -f ass -i sub.ass -brand isom -tag:v avc1 -map 0:0 -map 0:1 -map 1:0 -c:v copy -c:a copy -c:s ass -disposition:s:0 default Fname.mkv

ffmpeg -i $1 -f ass -i $2 -map 0:0 -map 0:1 -map 1:0 -c:v copy -c:a copy -c:s ass $RANDOM.mkv

I confirm this code is fine.

Thanks.
