Description Rex Dieter 2006-03-27 12:52:06 UTC

Spec Name or Url: http://apt.kde-redhat.org/apt/kde-redhat/SPECS/libmpcdec.spec
SRPM Name or Url: http://apt.kde-redhat.org/apt/kde-redhat/all/SRPMS.stable/libmpcdec-1.2.2-1.src.rpm
Description:
Musepack is an audio compression format with a strong emphasis on high quality.
It's not lossless, but it is designed for transparency, so that you won't be
able to hear differences between the original wave file and the much smaller
MPC file.
It is based on the MPEG-1 Layer-2 / MP2 algorithms, but has rapidly developed
and vastly improved and is now at an advanced stage in which it contains
heavily optimized and patentless code.

Comment 1 Matthias Saou 2006-03-29 11:31:59 UTC

I know that the musepack page says "patentless code", but it does seem like
something quite hard to be 100% sure of, no? Do you have any more information
about that claim? I've browsed through the website, FAQ, links etc. and didn't
find anything.

Comment 2 Rex Dieter 2006-03-29 12:55:51 UTC

No, I have no further information, but, IMO, it's pretty hard to *prove* it
doesn't contain patented code, especially if the dev's claim it.  I'm of the
opinion that their claim should be believed/respected, unless/until evidence
comes to light to the contrary.

Comment 3 Michael Schwendt 2006-04-01 15:13:06 UTC

Licence is not LGPL, but BSD (aka "New BSD" or "Modified BSD"):
http://www.opensource.org/licenses/bsd-license.php

Else: APPROVED

I've contacted upstream to seek for clarification with regard to the use
of the term "patentless code". The not-so-short response confirmed my
initial assumptions. The current code means to be "free of patents" in a
similar way like Ogg Vorbis (rpm -qi libvorbis). That statement on the
web page is quite unfortunate, as it mixed past and present and thereby
raises doubts for anybody who is not intimately familiar with the code.

Comment 4 Rex Dieter 2006-04-01 16:10:43 UTC

Thanks Michael for the clarification(s).

I'll import and change the license (not sure where I got LGPL from??)

Comment 5 Rex Dieter 2006-04-01 18:03:56 UTC

Imported, build queued.
