I'm trying to understand this:
[AES_128] REQUIRES the same 16-octet Initialization Vector (IV) to be supplied when encrypting and decrypting. Varying this IV increases
the strength of the cipher.
An IV attribute on an EXT-X-KEY tag with a KEYFORMAT of "identity" specifies an Initialization Vector that can be used when decrypting
Media Segments encrypted with that Key file. IV values for AES-128
are 128-bit numbers.
An EXT-X-KEY tag with a KEYFORMAT of "identity" that does not have an IV attribute indicates that the Media Sequence Number is to be used as the IV when decrypting a Media Segment, by putting its big-endian binary representation into a 16-octet (128-bit) buffer and padding (on the left) with zeros.
My question is:
The iv shuld be like this (for 10 at dec.):
or at binary?
