I have some flash actionscript code supposedly used to encrypt/decrypt using rijndael-128. If i were to use this code to encrypt something, what would the initialization vectors be?

You want to use the same random initialization vector for encrypting and decrypting

4.2. Rijndael Initialization Vector

           
               It is up to the entity in question how to obtain/compute
               the 32-bit IV. On Unix operating systems one can use
               reasonably   secure   random   number   sources   such   as
               /dev/random.
           
               IV should satisfy the following requirements:
                    .Unique (non-repeating from one packet to another);
                    .Varying "rapidly" (considerable amount of bits change
                      from one IV to another).
           
               It  is  preferable  but  not  required,  that  IV  is
               unpredictable.
