Optimized vorbis encoder for Linux (SSE instructions), I have built the binary - any interest ? Options

[The_Sven]

A quick look around the forum seemed to indicate that no-one has ever attempted to build Vorbis with Lancer optimisations for Linux ?!

So I spent a few hours fiddling and produced an executable:
- Linux
- aoTuV-beta5
- Lancer optimisations for SSE
- 32 bit (x86)
- statically linked
- around 3x faster compared to the standard aoTuV-beta5 build

I did not attempt to port Lancer's SSE2/SSE3 instructions to Linux because the difference between SSE/SSE2/SSE3 is minimal on the PCs I use.
(Intel Celeron M and AMD Turion 64x2)

Any interest? If so, I will post the binary.

I put the required patches and modifications under source control, so everyone can:
- build
- look at the diffs
- generate patches

Use the repository's web interface to browse it. You can also download the accelerated SSE Linux executable there.

Thank you for the binary. It is twice as fast as mainstream oggenc.
Unfortunately it accepts only wav files as input. Could you please add flac support?
You used aotuv-b5 version of 2006-10-24. Do you plan to make a binary of the latest aotuv-b5.7 (2009-03-01)?

FLAC support now added. Get the updated binary direct from the repository:

I will try to encorporate Aoyoumi's latest version. It will be a good test for Git ;-)

Thanks for both. Flac support works OK.
