Problems decrypting HTTP Live Stream

I have a single key encrypted HTTP Live Stream which decodes fine in Quicktime and iPhone. I'm trying to create a simple client application to do the decryption of the ts files. Right now I've used openssl to decrypt. I believe I have the correct arguments to openssl and I'm inserting the key and the IV properly. I can successfully decrypt the first .ts file in the stream but fail to decrypt after. I'm using the following script which I found in the archives here and I reversed to do decryption:

#!/bin/sh

hexKey=$(cat encryption.key | hexdump-e '16/1 "%02x"') 
hexIV='00000000000000000000000000000001' 开发者_Python百科
openssl aes-128-cbc -d -in ./multi_2.ts -out ./clear.ts -p-nosalt -iv ${hexIV}  -K ${hexKey}

where:

encryption.key is the key file I retrieved from the M3u8 stream file.

multi_2.ts is the second .ts file in the m3u8 stream file.

Any help would be appreciated.

The subsequent .ts files are probably fine, you just need to join them into one file in order to be playable:

cat clear*.ts > joined.ts

hexIV='00000000000000000000000000000001'

should be :

hexIV='00000000000000000000000000000002'

as multi_2.ts is the second .ts file in the m3u8 stream file.
