The MpegTSWriteStream structure contains a pointer to the service(ie program). If the stream can be in multiple programs, this association would have to be removed. This would complicate the calculation for PAT/PMT/SDT generation. The software would have to loop through each service for every packet sent do see if it is time send the tables again.
This may be a stupid question, but I understand that the PAT/PMT/SDT are send at specific intervals. Why not just call av_gettime() and see if it is time to send them out again? I've been reading this list for a while and calculations for how many packets to send before the PAT/PMT/SDT needs to be sent just keeps getting more and more complicated.
