Well, the reality is that srtdec should be replaced by a textdec - I 
that already - by having the srt demuxer produce proper text packets.

ttext/tx3g/movtext is MPEG4 Part 17. Although it's tempting to say its 
text, the standard goes way beyond that, and the pascal style strings 
have to
be accounted for as well. I intend to introduce separate encoders and 
for it. This change set has no direct relationship to this work - it's 
a precursor
to ensure you can get srt out of mkv files sanely.
