<i>utilizing Cisco&#x27;s free H.264 implementation</i><p>What difference does it make? It even seems backwards in some sense --- that writing code based on a freely available spec means you have to pay a license fee, yet someone else can give away their implementation freely? IANAL, so perhaps what we think of as the crazy and contorted bureaucratic mess that is the patent system would make sense in some strange and twisted way to those who designed it.
