tsparse and tsdemux

[i.nixman at autistici.org]

hello,

I have the following pipeline to stream a mpeg-ts:

gst-launch-1.0 videotestsrc ! x264enc tune=zerolatency key-int-max=1 ! 
mpegtsmux ! udpsink host=127.0.0.1 port=4455

then I use the following pipeline to save the stream to .ts files for 
later streaming as HLS:

gst-launch-1.0 udpsrc port=4455 ! tsdemux ! hlssink2 
playlist-root=http://127.0.0.1:8080 
location=/home/nixman/t/segment_%05d.ts target-duration=5 max-files=5


everything works as it should, but I have a question: if I add tsparse 
to the second pipeline before tsdemux, everything will still work 
successfully.
the question is why does tsdemux work successfully without using tsparse 
and when should tsparse be used?


best!
