I got the URL m3u8 which encrypted by AES - 128 example :

#EXTM3U
#EXT-X-VERSION:4
#EXT-X-ALLOW-CACHE:YES
#EXT-X-TARGETDURATION:14
#EXT-X-KEY:METHOD=AES-128,URI="HXa1HNC0GQGsG2Y4INatGdK3TAGsIAC3Gtw4HAPeSQCnTNLcTQK4INw1Ste0HQOsGNHdHXY5TNDeGQLcTASqHtU4INeqHQG1TdG0GXK0SQHfStw0IALbHAZeTgHbSgSrTQPcSdVbHU==.key",IV=0x37386530353837663566623166366230

....

from this m3u8 file, I can get key, IV param. I think chuck .ts URL was encrypted also. However, I have no idea about AES - 128 encryption.

Could you guys please help me to play this file by Exoplayer on an Android device?

Thank you
