All I can say is that some people do it and get away with it and some get corrupted encodes. I don't know why and don't have time to investigate. Theoretically, I believe it should work as the Nvidia driver is supposed to manage the contexts for the two different processes, but as I said, some people have had problems.

Hi Don,
I'm getting this error on Windows 7 with all versions of your app. cuvidMapVideoFrame: 208. I realize win 7 is still in beta, but i'm willing to help trouble shoot if you want. It's only a matter of time now before Windows 7 is released.

I've already reported it to Nvidia some time ago. The problem is not in my code and we just have to hope that they fix it in time.
I will rattle their cages a little. EDIT: Just sent this: "I have a user doing VC1 decoding on Windows 7 beta. He gets cuvidMapVideoFrame: 208. I believe we briefly discussed issues with Windows 7 a while back. Is this issue known and can we hope for a fix before Windows 7 goes final? The user is willing to assist in debugging."

I'm using build 7068 of windows 7. However the release candidate has just been leaked.
I'm using 181.71 which shows as the latest build for windows 7 on nvidia's site. I don't want to use the latest build for vista 185.68 as afaik this is WDDM 1.0. I'd prefer to stick to win 7 drivers which are WDDM 1.1. I'll install windows 7 RC tonight or tomorrow and try again. If that doesn't work, I'll try the latest drivers for Vista and report back. edit: WDDM http://en.wikipedia.org/wiki/Windows...y_Driver_Model

Using release candidate build 7100 of windows 7 and the drivers from automatic update 181.72 I still get the same error.

Same error
I'm getting same error when screen saver engages (switching users will likely to cause this too but I'm not sure, need to test it again) and when two or more DGVC1Decode processes trying to run, so in my case it is not related to any particular position in the fille. I'm using WinXP SP3 + 8600GTS + 178.24 driver. So, is limitation of CUVID server or a bug (or a feature ) ?

CUVID error, few more cases

So, can I nicely ask for a fix? |

Anyway, shouldn't there be a way for DGVC1Decode to simply stall (maybe with a dialog popping up for the user to terminate it) until it can reacquire the hardware, assuming that it's actually possible to do that (most games do it when you tab out of them and back)? I'd say that would be way better than simply erroring out - if it's doable, of course...

In WinXP switching users is not the same as log-off. When I re-encode h264 content, I use non NV version of dgavcdecode and have a queue of work for several days, however I can do all those thing without any impact on the processing.

Unfortunately it's more complicated than that, not only would it have to re-acquire a handle to a direct3d device but also reinitialize the CUDA decoder and feed in all the previous reference frames again so the DPB was valid.
