Bug 250334 – media-libs/celt-0.5.0 initial ebuild support with denormals fix

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Adeel 2008-12-09 02:02:45 UTC]

The CELT codec is an experimental audio codec for use in low-delay speech and audio communication. It is highly useful for applications with netjack or any realtime audio streaming application where using raw PCM is not possible, and the delay introduced by most codecs is unacceptable. Please visit http://www.celt-codec.org for more information.

Reproducible: Always

denormals patch

denormals are when if a float gets very small. ie by multiplying a value with 0.1 over and over again... it gets converted to a denormal. intel cpus throw an exception to calculate with them. so multiplying 2 denormals takes 100time longer than multiplying 2 normal floats. this is fixed upstream in the git version

Nice to see an initial ebuild here. Thanks for the work.

In the meantime, CELT 0.5.2 has been released (17th of Feb).

@ Gentoo devs: Is it possible to get this into the tree anytime soon? Work on the Mumble-1.2.0 branch has been started and Mumble 1.2.x will switch to CELT and therefore need it to successfully compile.

[Comment 5 Timo Gurr (RETIRED) 2009-08-12 13:24:59 UTC]

Sure. Taking this one since it's needed for Mumble and I'm already working on both, expect them to hit the tree during the next day(s).

celt-0.6.1.ebuild in CVS now, thanks Adeel!
