 For me reading srt files works fine. I tried something like "ffmpeg -i
 subs.srt subs.ass" and it works. I only have problems with writting ass
 subtitles to mkv files, but it is separate and more complicated issue.

 I do know mkvextract, but ffmpeg is more handy for what I am doing. The
 patch I attached is sufficient walkaround for me.

 I still believe that there is missing function for adding srt timecodes in
 livavformat. There is similar function for ass subtitles and ass are
 exported from mkv files without problems.
