[FFmpeg-user] Force dvbsub on a stream

[hans gerte]

Hi Folk, need some help.

i have some live streams (free to air) that have multiply audio and dvbsub
tracks.
i managed to transcode the stream to only use 1 audio and 1 dvbsub. but the
problems is that the dvbsub is not active until i selected it. so my
question is, is it somehow possible to force/burn it on the stream? i used
the "map" function to filter and use only the channels that i needed.
-map 0:1 -map 0:3 -map 0:6
0:1 = select video
0:3 = select the audio track
0:6 =  select the dvbsub track
