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.

av_gettime() represents the wall clock more or less, a mpeg-ts stream can be
muxed much faster than this so its wrong to use av_gettime()
timestamps must be used (the details of which and what intervalls are in the
spec)
