Looks good. I wrote a spec file last week, too, but I think yours is more
complete. One little comment: Not all of ogg vorbis is LGPL, the executables
are GPL.
("This package contains libvorbis, an LGPLed software implementation of
the Vorbis specification by the Xiphophorus company
(http://www.xiph.org/), vorbisfile, an LGPLed convenience library
built on Vorbis designed to simplify common uses and a number of GPL
example programs, utilities and player plugins.")

I noticed that too! Two weeks ago I fetched the source and created
my own mdk spec file.

I merged and greatly improved your spec file including a patch for
building shared libraries and developer files.
All these are attached to this mail. Comments are welcome :-)

Ogg Vorbis is a fully Open, non-proprietary, patent-and-royalty-free,
general-purpose compressed audio format for high quality (44.1-48.0kHz, 16+
bit, polyphonic) audio and music at fixed and variable bitrates from 16 to 128
kbps/channel. This places Vorbis in the same class as audio representations
including MPEG-1 audio layer 3, MPEG-4 audio (AAC and TwinVQ), and PAC.
Encoding: use `vorbize' (currently, only 44.1 kHz 16 bit stereo PCM)
Converting: use `mp3tovorbis'
Playing: use `ogg123'
WARNING, THIS IS BETA SOFTWARE.
Unlike the MPEG sponsored formats
(and other proprietary formats such as RealAudio G2 and Windows flavor
of the month), the Vorbis CODEC specification belongs to the public
domain. All the technical details are published and documented, and any
software entity may make full use of the format without royalty or
patent concerns.
WARNING: This is CVS code!! I did not find any beta versions.

On this machine (Celeron 400) mpg123 gives 5/7% of cpu consuming, whereas 17/18% for ogg123. xmms stuff seems to handle it better (2 times less time consuming for both). I agree this is much more, I think this comes from two things: . still beta software, will certainly be optimized . better encoding and use of adaptative bitrate To me, it's not enough to tell that we can't use it.

Well on P133 non-MMX the xmms oggvorbis plugin it can't do continuous playback (you get scratched plays at slow motion) at least with ISA sound card. But consider also that oggvorbis is quite new, while MP3 had several X86 asm replacement and optmizations due to many years of development, so maybe it is expected this also into oggvorbis. Bye.

From where I stand, the problem with Ogg Vorbis at this point is that it extremely expensive cpu-wise. On a p200, playing an Ogg stream consumes between 49 and 55% of processor cycles using ogg123 and as much as 77% with xmms.

[Cooker] mp3 is not free. use Ogg Vorbis.
Hi, As you may say, mp3 is not free. For example Linux-Mandrake cannot provide an mp3 encoder since Fraunhofer would sue us and/or our clients for patent infrigement. As a results, in late 1998 a new free software project started in order to produce a patent and royalties free compressed audio file format. Roughly, the size/quality is equivalent to the mp3. (but adaptative bitrate seems to be better handled) (e.g., it dynamically changes its parameters in order to keep optimal quality, relatively to the quantity of information that may vary throughout the audio stream). It is now in the state where it's useable. I included packages in Linux-Mandrake to encode/decode Ogg Vorbis, to convert from mp3 to Ogg Vorbis, and to play Ogg Vorbis from within the XMMS multimedia system. For more information please read my page: http://www.mandrakesoft.com/~gc/html/oggvorbis.html and/or install the packages `oggvorbis' and `oggvorbis-xmms' from Cooker. -- Guillaume Cottenceau -- Distribution Developer for MandrakeSoft http://www.mandrakesoft.com/~gc/
