please first document yourself and understand how this whole process 
works, who plays what role, and so on.
then you'll find the role of EXT-X-ENDLIST and maybe figure out a 
solution to not feed it to the client at all and gracefully continue the 
ongoing playlist after restart. a playlist preprocessor could help.
and then please understand why this is not an ffmpeg issue and shouldn't 
be its responsibility to have flags to create intermediary incomplete 
outputs. and this is for the simple fact the ffmpeg *is not* a streaming 
server. look to other solutions for that.
