DGAVCDecNV 1.0.13: GPU decoding on Nvidia

ATTENTION: If you do not use an Nvidia graphics card 8xxx or higher, this thread is not for you! If you want to assess the GPU performance, please read the section "Disable Display" in the users manual. And set the playback speed to Maximum under Options/Playback Speed! I am still optimizing frame rates and CPU utilization. Be aware that when serving through AVCSource() the performance will be comparable to that obtained with the display disabled (Disable Display option enabled). I'm also interested in finding out what streams fail with GPU decoding, so please report them, preferably with stream details and a sample.

My results for a 1920x1080 PAFF stream from the Hauppauge HD PVR with display disabled are: Frame rate: 46 fps CPU utilization: 2% My machine is Intel E8500 dual core @ 3.8GHz on ASUS Rampage Formula. Graphics card is eVGA 8500GT.

Jesus I've just bought 4850 :(

I might support ATI also. For now, let's get Nvidia done.

So you're telling us.. we're going to get GPU acceleration of decoding that we can actually frame serve? :) I'll hop on my desktop and try this out. I have a 9800 GTX on that computer. I'll go pop in some blu-ray discs and make sure those work properly too. I'm most concerned with the performance on those, since transcoding a Blu-ray is a massive pain. Edit: Unfortunately, I couldn't even copy nvapi.dll. It was locked by some process.. Trying to find out which one now.

Don't have an NVIDIA GPU to test this with, but I'll be watching with baited breath. :)
