...teway project. I have some results, but I still need some improments, because I'm still getting some error messages in the mail box system... If someone wants to help... it would be useful. 2006/1/16, Ralph Giles <giles@xiph.org>: > On Mon, Jan 16, 2006 at 04:43:56PM +0100, Christophe Augier wrote: > > > i'm not an expert in dsp but i've seen there is some code to run speex > > on omap C5X dsp so i was wondering what is the status of this code. > > Actually my goal is to run a voip application which uses gstreamer on > > an OMAP 5912 board.

my 2 cents but it looks like the logo was drawn using a vector graphics editor, so you may directly ask the author the .svg version ;-) - Christophe On Thu, Jul 30, 2009 at 9:40 AM, Sebastian Redl<sebastian.redl at getdesigned.at> wrote: > > On Thu, 30 Jul 2009 00:09:01 -0700, Chris Lattner <clattner at apple.com> > wrote: >> http://llvm.org/Logo.html >>

Hi, i'm not an expert in dsp but i've seen there is some code to run speex on omap C5X dsp so i was wondering what is the status of this code. Actually my goal is to run a voip application which uses gstreamer on an OMAP 5912 board. As there is already a speex codec for gstreamer, i was wondering if this plugin can already use the dsp power or if there is the need for a new plugin. thank

...'s some good news. I think I won't be of much help except for testing but i would be glad to invest some time in it.

I experimented voip with alaw and ?law on the ti omap 5912 board running at 192MHz and it basically

I'll check that next week. thanks, - Christophe
