Well, on the box you still need to talk somehow to the MP3 playing program. > >mpg123 is probably the fastest one, although all of them will be > >fast enough. > > Ok I saw mpg321 picked up that project and depends on madlib like a ton > of other players. That's not how it happened. mpg123 is a floating point decoder. That code has also been used in XMMS and MPlayer. libmad is a completely independent code base and uses fixed point arithmetic. Years ago, when mpg123 was stuck at 0.59r, unmaintained and crufty, and with a problematic license, somebody decided to throw a rough clone together as a programming exercise by combining libmad and libao with some glue and under the GPL--thus was born mpg321. Eventually mpg321 was abandoned as well, but in the meantime mpg123 had been picked up again and the project is alive and well today, including a cleaned-up license. Lately mpg321 has also been revived, sort of. Historically, there was also a bit of jostling over the patent situation, where the mpg123 author said that MP3 patents probably applied and the libmad author thought they might not because of the fixed-point code, but by now they are probably expired anyway. Speaking as the guy who is the OpenBSD maintainer for both ports, I very much prefer mpg123, and if you are concerned about CPU usage, it should be the fastest MP3 decoder around (unless you are on an architecture without floating point, i.e., ARM). -- Christian "naddy" Weisgerber na...@mips.inka.de
