How to understand func NewMediaPlaylist(winsize uint, capacity uint) (*MediaPlaylist, error) correctly?

When I check the m3u8 file

#EXTM3U

#EXT-X-PLAYLIST-TYPE:EVENT
#EXT-X-ALLOW-CACHE:NO

I would like to take the first three Segments into []*m3u8.MediaSegment, then build a new MediaPlayList out of it, there are no such things like winsize, capacity, how am I supposed to assign the value?
