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!
http://neuron2.net/dgavcdecnv/dgavcdecnv.html 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. Last edited by Guest; 10th March 2009 at 01:22. |

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. Last edited by Guest; 13th September 2008 at 14:34. |

So you're telling us.. we're going to get GPU acceleration of decoding that we can actually frame serve?
![]() 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.

Well I can't seem to actually figure out how to copy nvapi.dll without Windows throwing a hissy fit about it. I'm hesitant to copy the new NVApi.dll (dated Aug 2008) over the old one (Feb 2008) in my system32 directory, but I'll give it a shot I suppose. All in the name of faster decoding I suppose..
Got Unlocker working.. Unfortunately I have explorer.exe, taskeng.exe, and rundll32.exe using it on my laptop. My desktop is using it for rundll32.exe, nvsvc32.exe, and ntune.exe. I hate dependencies.

I was just in time to cancel my order when i read about this upcoming release.
I'll wait some time before i decide to go Nv though, and i might still get the 4850 even if DGIndex doesn't Ati support Ati, cause i think is better imho. But in the mean time i give all kudo's to Neuron2 for this step in development, and i'll keep watching progress ! |

Still, I'd like to see both supported -- If either side comes out on top (and I usually go with the one who has the faster card) then if that one happens to be unsupported I'm in a bit of an unfortunate position
![]() @neuron2: On my both my computers I received the error message on simply opening DGAVCNV saying: Code:
ERROR: cuInt failed (100) Hit Yes to continue .... Code:
GPU decoder: Failed to create video decoder.

If we can't get the DLL thing sorted, I'll contact Nvidia about it, but you can always install the CUDA driver and toolkit:

Is it just the CUDA driver that's needed? I tried installing the SDK and that did nothing for me.
I'm installing Driver --> toolkit now, I'd really love to get this running.

I don't know the install details yet. You need to install the CUDA driver and toolkit to do it the kosher way. I am hoping to find a way to avoid that for users.
When you install the CUDA driver say Yes when they ask if you want to replace your existing (possibly newer) driver. Last edited by Guest; 13th September 2008 at 15:57. |

I was using DGAVCNV to open a m2ts file ripped from a Blu-ray, after I got the first error message and I clicked "yes" to ignore this, I got the second one too. But that shouldn't be anything unusual since it already told me something failed to initialize. This was before I had the "correct" dlls btw

Now my computer won't start up.. I'll get back to you on this, my main desktop has been having various issues for a while now. I think it's a bit overdue for a reinstall of XP.
