I don't think that an additional "exporting" function would be a good idea.
Something like that would certainly be better done in an external tool.

What might be a good idea would be to fix the PTS in the frames (both audio
and video) and the 'time_code' values in the GOP headers while doing the
editing process (inside cCuttingBuffer::Action()), thus resulting in a
"smooth" continuous stream. I don't know if this can be easily done without
tearing all the video and audio data apart (but I guess it _should_ be
possible). However, I'm not going to implement this myself, so if anybody
would like to try this...
