The -txt_page number i get by using VLC. So now i have the .srt
file. Don't know how else to get ffmpeg to pick that one subtitle.
Then i encode my video as i always do.
Then i combine it with:
ffmpeg -i 'Beck _je for _je (4).mp4' -i 'Beck _je for _je (4).srt'
-c:v copy -c:a copy -c:s mov_text 'test.mp4'
This seems to be working. But is a long way to go.
ffmpeg -ss 00:04:45 -c:v h264_mmal -i 'Beck_ _je for _je (4).ts' -to
00:05:00 -map 0:0 -c:v h264_omx -b:v 4800k -map 0:2 -map 0:3 -c:a
copy -map 0:1 -txt_format text -txt_page 599 -c:s mov_text
-metadata:s:s language=dan 'Beck Øje for øje (4).mp4'
Wouldn't this work? But again, without a sample we can't verify.

Hey Reino.
Just a test as you suggestet, but it will create a new error. I
correctet the channels that need to be encoded.

I finally got the right commandline. I'll provide this solution for
others, so they don't have to spend so much time on a simple task.

To be encided: Video 0:0, Audio 0:2 and subtitle stream 0:1:2 (dan)
It's importent to have -txt_format text -txt_page 599 -fix_sub_duration
in front of input file.
The number for txt_page 599 is found by playing file in VLC and choose
the subtitle needed. It will be showed in the tele-text area.
-fix_sub_duration will ensure that the subtitle is showed one by one.
Without it, first subtitle come on to screen. Then the second will push
the first one up on screen. The third subtitle will push 1. and 2.
subtitle up and after 5 subtitles, your screen is full of subtitles!
So i ended up with this commandline for the file:
ffmpeg -txt_format text -txt_page 599 -fix_sub_duration -ss 00:02:40
-c:v h264_mmal -i 'Beck_ _je for _je (4).ts' -to 01:32:10 -map 0:0 -c:v
h264_omx -b:v 4800k -map 0:2 -c:a copy -map 0:1 -c:s:0 mov_text
-metadata:s:s language=dan 'Beck(4).mp4'
Issue is closed.
