[FFmpeg-user] add SRT to dvb TS file

[Wojciech Wydmuch]

Hi,
What is the best practise to add subtitles (srt file) into TS file?

Actually i have an error with converting text to bmp
MBP-user:$ ffmpeg -i movie.ts -i subs.srt -c:v copy -c:a copy -c:s xsub
-map 0 -map 1 output.ts

Subtitle encoding currently only possible from text to text or bitmap to
bitmap

Any help ?
Thanks
