Well, the reality is that srtdec should be replaced by a textdec - I 
discussed
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 
just
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 
decoders
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.
