 FFmpeg can't mux several subtitles streams in M2TS while it could do (BDMV
 files are M2TS).
 How to reproduce:
 {{{
 % ffmpeg.exe -canvas_size 720x480 -i C:/Users/Me/Temp/title04.mkv -strict
 -2 -f mpegts -map 0:0 -filter:v:0 yadif,scale=940:400 -c:v:0 libx264
 -crf:v:0 19 -map 0:1 -c:a:0 libfdk_aac -b:a:0 330k -metadata:s:a:0

 The trancoding goes to 100% witout error:
 ...

 But there is no subtitles in output file.

 Same command with -f matroska and .mkv output file works.
