# filler_path are for the GUI only at the moment
# filler_clip get handle different, when a new length needs to calculate
# blackclip is for stream copy mode
# time_shift adds or subtract seconds to the clip start,
# this is usefull for example for hls, because it have a big delay
# the value will be added to the clip begin
# put 0 if you don't need it
# map_extension is only for special purpose,
# when your playlist have a different extension, then the originial clip
# example: map_extension = [".mp4", ".mkv"]
