Fast JPEG encoder

Any suggestions?

This is to generate a lot of JPEG files on the fly server-side.

Re: Fast JPEG encoder

You have:
http://software.intel.com/en-us/intel-ipp
and the AMD sibbling.

GPU accelleration is certainly the best approach, in terms of speed.
Some solution are pricy,  other open source - see http://sourceforge.net/projects/gpujpeg/

Re: Fast JPEG encoder

Thanks! A bit out of budget as it's for experimenting (don't know if you caught my Mandel experiment why it was online).
GPU is fast, but servers with GPU are very expensive.

Currently my best solution is libjpeg-turbo (http://libjpeg-turbo.virtualgl.org/) using the headers from http://www.opengl24.de/header/libjpeg

Compression speed is 7 to 8 times faster than TJPegImage, I'm not entirely sure vs IPP (they claim to be in the same ballpark).

Re: Fast JPEG encoder

I suspect libjpegturbo is therefore the best option for you!
