David Schleef a écrit : > MPEG-1 audio layer 2 has never been patent encumbered, encoding or > decoding. There just isn't a good library that has been wrapped. Mpeg-1 audio Layer II is covered by some Patents from Philips (and possibly other companies, Philips is just the one that immediately came to my mind), and Mpeg-2 Layer II even more. There was not much public noise about them because it was not commercially worth it and it was better to use those patents to gather fees/settlements from Layer III implementors/sellers/distributors. -- Gabriel |
