[FFmpeg-user] subtitles from DVB streams

[vmrsss]

Hello there,

	I have got a stream (a DVB-S2 from EyeTV) which looks like in the output below. Can please anybody explain how I could use ffmpeg extract the subtitle track and dump it either as it is or convert to some meaningful format, eg srt or idx/sub ?

thanks.
