(Update: no, this isn't it. see my other answer)

Looks like you're providing the key and the iv in hex format, whereas I'm pretty sure you need to provide the actual key/iv bytes directly (that your encrypted string is coming out in hex format is because you're using encrypt_hex) which means you instead need something like 

-key => pack('H32',$key),
-iv  => pack('H32',$iv),

but I don't know for sure since the hex you've provided for your key/iv only specifies 8 bytes and AES requires 16.
