This is the wrong approach to fixing this however, it should be
understood first why its not doing this transparently right now.
hlsenc uses the mpegts muxer like one would use any other muxer, so
why does autobsf not get used?

If we understand that, maybe it can be fixed in a more generic way,
and not end up in ugly hacks in hlsenc.

PS: now to the list as well, please just mail to the list, no need to
directly mail anyone.
