Comment (by cehoyos):

 Iiuc, there is a bug: Our hls muxer does not conform to the specification
 and produces output that is incorrect.
 Is that correct? If yes, please explain how this can be reproduced. (You
 know what I mean with ''explain''?)
 I know that you understand the ticket and I realize that whoever will fix
 this already understands the issue (and possibly already knows how to fix
 it). but ideally every ticket should be reproducible for every user. This
 is particularly important in the future: The commit fixing the ticket
 might (in theory) introduce another problem and whoever wants to fix it
 may not know so much about hls...
 Or said differently: It is great that you added a link to the
 specification and quoted the relevant paragraph, it will make somebody's
 life much easier. But as said previously this analysis (no matter if
 helpful like in this case or disturbing like in other tickets not created
 by you) should never replace the actual bug report.
