Hi,

I used the onHTTPCupertinoEncryptionKeyVODChunk to encypt the HLS Vod, when I add the key rotation feature:

encInfo.setEncMethod(CupertinoEncInfo.METHOD_AES_128);
if( ( chunkId ) >= 4 ) {
encInfo.setEncUrl("http://mycompanykeyserver.com/authenticate.aspx");
encInfo.setEncKeyBytes( "0123456789ABCDEF".getBytes() );
}
else {
encInfo.setEncUrl("http://mycompanykeyserver.com/authenticat1e.aspx");
encInfo.setEncKeyBytes( "1123456789ABCDEF".getBytes() );
}

encInfo.setEncIVBytes(BufferUtils.decodeHexString("FEDCBA9876543210FEDCBA9876543210"));


#EXT-X-KEY:METHOD=AES-128,URI="http://mycompanykeyserver.com/authenticat1e.aspx",IV=0xfedcba9876543210fedcba9876543210
#EXTINF:11.25,
media_0.ts
#EXTINF:11.25,
media_1.ts
#EXTINF:11.25,
media_2.ts
#EXT-X-KEY:METHOD=AES-128,URI="http://mycompanykeyserver.com/authenticate.aspx",IV=0xfedcba9876543210fedcba9876543210
#EXTINF:11.25,
media_3.ts
#EXTINF:10.208,
media_4.ts

I can't decrypt the media_3.ts using the key 0123456789ABCDEF, but I can decrypt the media_3.ts using the key 1123456789ABCDEF correctly.
Is there something wrong with me?
