ID3v2 frames ain't MPEG frames (it's just a collision of terms), so no MP3 restriction apply to ID3v2 either. Curiously, www.id3.org a.k.a. www.id3v2.org is no longer available. I hope it's a mere coincidence :-) > > Index: ports/audio/mp3_check/Makefile [...] > It doesn't decodes audio, it just looks at some values in the frames > (e.g. bitrate, number of channels, ...). The greedy mp3 patent holders may easily claim that looking at the values costs money, too. At least, that's the feeling I've got after taking a look at www.mp3licensing.com. Hence this case isn't as easy as that of ID3. -- Yar To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
