there is no work on the reference tools because it's not very portable (way less than the current asm optimizations). the third party implementations are good enough I think. --- On Fri, 1/1/10, Sumit Gupta <sumitg at gmail.com> wrote: Is anyone on this mailing list working on enabling FLAC using GPUs? There is CUDA (GPU) accelerated FLAC encoder available now at:http://www.cuetools.net/doku.php/flacuda It has a chart with speedup results and here is a summary:Compared to reference flac 1.2.1 on Core i7 940, it runs approximately 10 times faster on GeForce GTX 285, when using higher compression ratios (modes -7, -8). FlaCuda -8 is faster than flac -0, and provides better compression than flac -8.? I am not a FLAC developer, but am curious to find out how 3rd party projects like this oneare interfaced into the FLAC sourceforge project. Thanks
