Changelog: Changelog:
-> http://www.iqiyi.com/common/flashplayer/20150612/MainPlayer_5_2_23_1_c3_2_6_5.swf
In this version do not directly use enc key
gen enc key (so called sc ) in DMEmagelzzup.mix(tvid) -> (tm->getTimer(),src='hsalf',sc)
encrypy alogrithm is md5(DMEmagelzzup.mix.genInnerKey +tm+tvid)
how to gen genInnerKey ,can see first 3 lin in mix function in this file

In this version ,it changes enc key to 'Qakh4T0A' In this version ,it changes enc key to 'Qakh4T0A'
consider to write a function to parse swf and extract this key automatically consider to write a function to parse swf and extract this key automatically
