I am searching for a detailed MP1 and MP2 specification to write a decoder for both. And by the way if someone has a big and detailed aac(+) specification i could also need it.
So if someone has a good documenation or specification of these codecs i would be very thankful

Oh and another question. Am I allowed to create a mp1/2 decoder and publish it as freeware?
Or do I have to pay first. |

I am not a lawyer, but ffmpeg decodes both MP1 and MP2 and is available under (L)GPL. ffmpeg also encodes MP2. ffmpeg obviously also implements codecs with licensing terms that do not allow distribution without licensing fees. However, in case of MP2 it appears that all patents *may* have expired by now http://en.wikipedia.org/wiki/MPEG-1#Patents |
