What I’m trying to achieve that from an mpeg ts file with teletext subtitles in it I can come in one step to an mp4 file with mov_text subtitles in it.
Instead of first using telxcc to extract an mov_text file which I combine in a second step to an mp4 with mov_text subtitles.

I changed the subtitle part to
-c:s mov_text -metadata:s:s:0 language=dut -map 0:0 -map 0:1 -map 0:2 -txt_page 888 -txt_format text

and changed subrip to mov_text
Codec AVOption txt_page (list of teletext page numbers to decode, * is all) specified for output file #0 (base.mp4) is not an encoding option.
I’m probably too stupid to understand what it wants more. I tried 888,42 888,* to no avail.
