What we do know is that various standards FFmpeg supports contain vague
hints that any conforming implementation might be subject to some patent
rights in some jurisdictions, examples for such statements are:
ITU draws attention to the possibility that the practice or implementation of this Recommendation may
involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence,
validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others
outside of the Recommendation development process.
