IMHO it doesn't make sense to push data you receive in userspace
into the kernel for demuxing (at least if there is no hardwar demuxer).

Demuxing a TS to extract video and audio is not difficult, check
out e.g. libsoftmpeg or the stuff on www.metzlerbros.org/dvb/.
Extracting an object carousel however is beyond me...
Maybe http://sourceforge.net/projects/libdsmcc/
