Your patch treats teletext data as if it were subtitles, putting it in
the demuxer stream dedicated to subtitles. But teletext in MPlayer is
handled separately from subtitles, and its decoder has a different
interface than that of subtitles decoders (see update_subtitles() vs
update_teletext()); that's why in my patch teletext is decoded without
use of demuxer streams, calling directly teletext_control() instead.
If teletext data were treated as subtitles, update_subtitles() should
decode it via the teletext decoder interface, but displaying teletext on
the screen would still be taken care of by update_teletext(). Is that
what you want?
