Cuda decoding

[b33rman]

Ok,

So far from what i have read is that the geforce 8800's are not supported by most encoders for gpu acceleration. I have read up on a program called badaboom v1.1.1 that supports most all cuda products, the 8800's included. it also outputs to mp4, also no 5.1... boring... well my question is if it does "accelerate" the encoding significantly from my other method (xvid4psp), can i just demux the video from the mp4 container, and remux the video with ac3/dts? If not, is there any other program that will encode using the 8800 gpu? I just keep hearing good things about gpu support with encoding video files faster, particularly h.264. 18-24 hours just can be too long for me on a q6600 2.4, vista-32, 4gb ram, 500sata, 8800gts (512).

Thanks

Check Badaboom very carefully, as the initial release at least supported only a few basic encoding profiles, which might speed up encoding for an iPod or AppleTV, but not for anything that can play quality video. There is also some question over just how much of a gain you get using the GPU when comparing to an encoder that can make full use of a Quad Core processor.

It doesn't accelerate xvid4psp or any front end based on x264. It uses it's own encoder, and doesn't integrate with existing software

Low quality encoder, search for some screenshots and reviews there are quite a few. The latest release has some improvments - it offers main profile instead of just baseline (It still doesn't offer high). When using similar quality settings, it's actually slower than x264 on a quadcore.

If you don't care about quality, or only use low quality devices like ipod or other portable devices, it will be fine - that was it's intended target anyway.

Here's a recent review with a few benchmarks: http://www.anandtech.com/showdoc.aspx?i=3475

The fastest graphics cards were able to slightly outperform a quad core I7 CPU. 9500 and 9800 cards were slower.
