mpegtsmux pmt-interval/pat-interval

[Greg Stahl]

Ok, so switching to the x264enc module fixes the problem, even without
using the "key-int-max" parameter, though setting the parameter to a low
value does enable VLC to pick up the stream quicker than the default.

Interestingly though the mpegtsmux is still only sending the PMT and PAT
once according to log output even with the properties set to 3000:

gst-launch-1.0 --gst-debug=x264enc:6,mpegtsmux:9 videotestsrc ! x264enc !
mpegtsmux pat-interval=3000 pmt-interval=3000 ! rtpmp2tpay ! udpsink
host=192.168.11.255 port=26000 auto-multicast=TRUE sync=true 2>&1 | grep
--ignore-case pmt

tsmux.c:1222:tsmux_write_pmt: PMT for program 1 has 1 streams
