P.s all the files can be downloaded on googledrive

Recently I've got some m3u8 files from the developer tools with Google chrome,but when I tried to open them with iTunes and potplayer ,they seemed unable to open them.
The head of the encrypted m3u8 is just like

#EXTM3U
#EXT-X-KEY:METHOD=AES-128,URI="http://touch.xueersi.com/video/getVideoKey/121263"
#EXT-X-VERSION:3
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-ALLOW-CACHE:YES
#EXT-X-TARGETDURATION:13
#EXTINF:10.74,
http://v2.xesv5.com/2013/06/fbfdd529...8a1a10/0000.ts
#EXTINF:10.64,
http://v2.xesv5.com/2013/06/fbfdd529...8a1a10/0001.ts
#EXTINF:10.64,

Then I tried to get some unencrypted files on the video sites like YouTube, one of the unencrypted m3u8 file is like

EXTM3U
#EXT-X-TARGETDURATION:12
#EXT-X-VERSION:2
#EXTINF:3,
http://101.226.184.113/6971307046F3C...&ts_keyframe=1
#EXTINF:5,
http://101.226.184.113/6971307046F3C...&ts_keyframe=1
#EXTINF:4,
http://101.226.184.113/6971307046F3C...&ts_keyframe=1
#EXTINF:10,
http://101.226.184.113/6971307046F3C...&ts_keyframe=1

The ts files from this m3u8 can be easily opened with windows media player.........
Could you please tell me how to decrypt AES-128 encrypted m3u8 ??(like the first m3u8)
or whether python can do this??(if possible pllease show me the scourse code

Thanks.
