做数据跳转时，发现M3U8的内容为：
#EXTM3U
#EXT-X-TARGETDURATION:12
#EXTINF:8,
slice-1.ts
#EXTINF:8,
slice-2.ts
#EXTINF:7,
slice-3.ts
#EXTINF:7,
slice-4.ts
...
#EXTINF:10,
slice-799.ts
#EXTINF:4,
slice-800.ts
#EXT-X-ENDLIST
其中没有#EXT-X-DISCONTINUITY属性，导致依照#EXTINF时间列表的偏差比较大。不能准确的找到跳转的位置。我已经尝试在这个范围内预存五个ts片段，但是仍然不能顺利的到达要播放的准确位置。我使用VLS得到以下的测试内容：
