Bug#477806: ITP: djbfft -- extremely fast library for floating-point convolution

[Fabian Greffrath]

Package: wnpp
Severity: wishlist

Package Name:   djbfft
Version:0.76
Upstream Author:D. J. Bernstein
URL:http://cr.yp.to/djbfft.html
License:Public Domain
Programming Language:   C

 djbfft is an extremely fast library for floating-point convolution.
 The current version holds most of the speed records for
 double-precision FFTs on general-purpose computers.
 .
 djbfft provides power-of-2 complex FFTs, real FFTs at twice the
 speed, and fast multiplication of complex arrays. Single precision
 and double precision are equally supported.

Yes, it does exactly that (and uses xine's own memalign function).

 I've never heard of this before, too. However, the source code can be
 found at 

 It is Copyright 1999, D. J. Bernstein but does not contain a license. I
 doubt that it is suitable (or even useful) for Debian.


DJB has since placed all his future and past software in the public
domain. Perhaps ping him if you need clarification of this.

I have prepared packages in the pkg-multimedia SVN. However, since ATM 
no other package than a52dec seems to benefit from this library, I am 
still reluctant to upload it to Debian...

Heya

So are you going to upload gjbfft to debian?

Because a52dec is out of sync in Ubuntu. We have applied a patch which
simply removes the silly warning "No accelerated IMDCT transform
found" #441693

So do you want help with gjbfft? Or is there really no point in having
it in the archive.
Or would you consider applying patch to a52dec to remove the warning?

BTW do you want help with a52dec? Eg. fix lintian warnings, libtoolize
and convert to DEB5, DEB3, quilt, dh7 or CDBS etc

Cause I have a little bit of time to do this. (I'll send git format-patches)

No, not really. I have prepared packages in our SVN repo [1], but I 
think it's unreasonable to upload just another library package to 
Debian for the sole purpose of fixing a warning in another library.

I'd favour actually fixing it, though. Simply removing a warning is 
not a method I would consider valid to get rid of it.

Well, at the moment I am the only (active) maintainer for a52dec in 
Debian, but my interest in the package could be more vivid, I admit. 
I'd highly appreciate if you could help out a bit and bring the 
package to the newest packaging standards.

That sounds perfect, because the packaging is actually tracked in our 
GIT repository at [2] now. To work on the package I highly recommend 
you to apply as a member of the pkg-multimedia team on Alioth.
