DGDecNV
AVC/MPG/VC1 Decoder and Frame Server



Release Notes
DGAVCDecNV Development Dialog with Nvidia


DGDecNV is a decoder/frameserver for AVC, MPEG2, and VC1 streams that runs on the GPU of Nvidia graphics cards that support CUDA video decoding. That means the card must have a VP2 or greater engine. VP1 is not supported! You can check which engine your card has here:

Table of Nvidia GPUs

You can also check here (this table lists more chipsets). You card needs G84 or greater in the architecture column.

Version 2048 and beyond drops support for Compute Capability 1.0 (sm_10) cards. You can see at this link which (older slower) cards are affected: CUDA GPUs.

This program requires a license that you can obtain from me by donating $15.00 to become a registered supporter. You may obtain your license by clicking on the donate button below. Note that you do not need to have a PayPal account; you can pay with a credit card account also. After your payment is verified, I will contact you by email to send you the executables and a login to the license generator.

Your activation is tied to your first active network adapter. So if you replace that, you will need to add a new entry to your license file. This supports cases where you use multiple machines, or you switch network adapters on/off. You will receive a login to an online license generator that will allow you to generate the license entries that you need.

Your activation includes all future versions of the program at no cost. Also, please note that only one donation is required to enable all of my licensed tools. You don't need to make multiple donations.

For support I encourage you to use my support forum rather than email, so that others may benefit.


Please be aware that until the system is automated I can process activations only intermittently,
so be patient if your activation seems delayed. Please allow 3 days before thinking there is a
problem, to allow for unforeseen absences, etc.


For access to the binaries, use this link:

Get DG Tools Binaries Access

After entering your user ID you will receive the access details and a link.


Here are the CUVID Server and a sample client application that works with the server (both with source code). Also included is a document describing how to interface programmatically to the CUVID Server.

CUVID Server Version 2.0.0 beta 1
CUVID Client Sample Application Version 2.0.0 beta 1


If you are an expert in AVC encoding and transport, you may be interested in my tool VBVChecker. Your license for DGDecNV will enable it. In fact it doesn't require an Nvidia card at all, so feel free get a license if you want this but don't have an Nvidia card. A similar tool from Elecard costs $350! Put your license file in the same directory as VBVChecker.exe.

VBVChecker 1.9
