Maybe you may think in Opus http://opus-codec.org/ as it is open,
royalty free (mp3 is not free, you must pay royalties for the encoder
side) and source code is C89 so it must be compilable (libopus) in
almost any platform without a titanic effort.
mp3 is not free?
According with
https://en.wikipedia.org/wiki/MP3#Licensing.2C_ownership_and_legislation
It's royalty free in European Union. And, in USA, still valid patents
will expire along 2017. After 31 December 2017 will be completely
royalty free in USA also.
Don't know rest of the world. Can it be worse than in USA?
Hello,
You are right, my working with MP3 technology was in 1999 so my
"standards" are very old :-)
Anyway Fraunhofer Institute which holds most known patents about MPEG
Layer III does not say "Patents expired" so maybe they can have a later
patent over technology trying to enforce it in a future and keep control
of the royalties.
Releasing a mp3 codec now could be safe in Europe (and 2018 in EEUU) but
a hardware piece could be a problem if a later patent appears in the
game. In the other hand as all known patents has expired I think no
court will be against you, maybe a "cease and desists" at most.
Anyway mp3 technology is surpassed a lot by others.
