  Why not just ... use that library instead of duplicating code from it ?

  An acceptable change would be to have tsdemux/tsparse accept PAT/PMT as
downstream events (i.e. coming from upstream). This would also be the
longer-term way of handling fast-dvb-startup also (dvbsrc/dvbbasebin could
cache the PAT/PMT for various channels and push-them asap as in-band events to
notify tsparse/tsemux of upcoming streams).

  In your case it would then end up being:
  1) Create PAT/PMT sections with the mpeg-ts lib
  2) Wrap them as GstEvent
  3) Set/Send those events on tsdemux/tsparse

  There is another bug report regarding adding support for MpegTSSsection as
GstEvent, you could re-use/extend that (and I should review it :()
