Yes but the *-caching for the TS demuxer comes from rtp.c.
It was 1000 times lower so nearly 0, with such low caching, VLC does not
work (you will have audio pts problems, frame skips, ...)

It did not work because the *-caching value returned was way too low,
substracting the caching was workarounding this issue (you were doing
the es_out job).
