I'm guessing it is related to this:

As the access on the event parameters fails because there is some refcounting
issue apparently it ends up always using COUNT=0 which will prevent hlssink to
create the correct segment file names.

I couldn't find anything obviously wrong with mpegtsmux event handling or in
h264parse or rpicamsrc but I also noticed that the line numbers are not
matching perfectly with the source, perhaps this has already been fixed
usptream?

Also replacing rpicamsrc with videotestsrc works here on the desktop.
