and net-sections will be download when playing at the same time if it needed.
a - l1 - b - l2 - c


now, if seek to 0 and play:
    a - l1[5~26] - b - l2[56~89] - c
    -> a -> b -> c  and a/b/c will to download if it needed


now, if seek to 20 and play:
    l1[20~26] - b - l2 - c
    -> b -> c  and b/c will to download if it needed


未来计划
todo: cahce m3u8

m3u8分为1级和2级，目前最多2级但较复杂，计划支持1级的缓存
m3u8  index.file
         01.ts
         02.ts
         03.ts
         ...        
no range, when playing and cahce -ts segments
