[lkmc79]

hi, nice to meet you.
i have a question about iPad2.
i saw the technical document about encoding settiong of http live stream.
in case video, iPad2 is support Main Profile Level 3.1.
i think, therefore Main Profile Level 3.0 have to support too.
so, i try to test ts file base on Main Profiel Level 3.0. but it is can't play on iPad2.
if ts file base on Main Profile Level 3.0 is can play, i want to know what to do.
please can you advice to me?
