I would guess that it > is, because I haven't heard of any other implementations. I have reas somewhere that one of their algorithms (the 8 Kbit/s) is not proprietary. The only other 8Kbit/s alg. that i know of is in the MPEG layer 3 specification (which I don't have, they cost money; also there is no freely available implementation, at least of the encoder). > Unfortunately there's still no RealVideo/FreeBSD. on the other hand the linux implementation works reasonably well with the emulation code and latest patches (Real probably used the wrong calls to keep audio and video in sync, so you have to make the emulation layer aware of this and fool the application...; i tested this several weeks ago, maybe they have fixed the problem now) Cheers Luigi -----------------------------+-------------------------------------- Luigi Rizzo | Dip. di Ingegneria dell'Informazione email: luigi@iet.unipi.it | Universita' di Pisa tel: +39-50-568533 | via Diotisalvi 2, 56126 PISA (Italy) fax: +39-50-568522 | http://www.iet.unipi.it/~luigi/ _____________________________|______________________________________
