Hi UE4 Answerhub,

I’m trying to understand more about pixel streaming through the demo UE4 provide, however I’m receiving the error below when trying to open the modified shortcut of the .exe

Assertion failed: Result == NV_ENC_SUCCESS
[File:D:/Build/++UE4+Licensee/Sync/Engine/Source/Runtime/AVEncoder/Private/Microsoft/Windows/NvVideoEncoder.cpp] [Line: 452]
Unable to open NvEnc encoding session (status: 10)

I’ve seen a 2 or 3 others have had this issue however there has been no solution online. I have so far tried updating the graphics drivers and adjusting the pixels to be 1920 x 1080 on my monitor. There is one idea given in a thread that an ultra wide monitor can affect this? Is this possible?

Does anyone know how this can be fixed / what the problem is?

Thanks for the help,

CHG

I am facing the same issue. Did you find any solution ?

You need to install Nvidia video encoding/decoding SDK on your machine (on top of driver, CUDA, etc)

Do you now if 1080TI work with Pixel Steaming?
