So i can't reproduce nvenc fail to render for now

Interesting, I am at a loss for an explanation.

"Failed to open backend VDPAU" as well as all of the other errors would be due to the AppImage being created on a computer with different graphics hardware that does not have that capability.

No, i'm using appimage.

Today I ran the CineGG render (after rebooting my laptop).
And as far as I can tell from the preview of the rendering process in the Compositor window (it's going fast) - Nvidia GPU encoding is working again for me

Here is the stdout of a successful render via nvenc:

export __NV_PRIME_RENDER_OFFLOAD=1
export __GLX_VENDOR_LIBRARY_NAME=nvidia
export __NV_PRIME_RENDER_OFFLOAD_PROVIDER=NVIDIA-G0

@cinuzer

@andreapaz

Did you build/compile CinGG yourself or are you using an AppImage or one of the package files at:

https://github.com/einhander/cin-gg-packages/releases

Unfortunately, I have not found a computer to test nvenc here yet but have 1 more I can look at. I am hoping that Andrea has tested this since we upgraded to ffmpeg 6.1 recently and can verify that it is working.

When you say it is not using the GPU, have you also looked at the startup window where you started CinGG to see if there is the error message: "Cannot load libcuda.so.1" ?

Run h264_nvenc.mp4 via Nvidia GPU in Nvidia Prime mode (GPU offload)

Hi,
i'm runing my laptop in Nvidia Prime (Nvidia On Demand, Hybrid graphics) mode and trying to run nvenc in CinGG via GPU Offload.

Here is my start command:

export __NV_PRIME_RENDER_OFFLOAD=1
export __GLX_VENDOR_LIBRARY_NAME=nvidia
export __NV_PRIME_RENDER_OFFLOAD_PROVIDER=NVIDIA-G0
export __VK_LAYER_NV_optimus=NVIDIA_only
export LIBVA_DRIVER_NAME=nvidia

firejail --env=__NV_PRIME_RENDER_OFFLOAD=1 --env=__GLX_VENDOR_LIBRARY_NAME=nvidia --env=__NV_PRIME_RENDER_OFFLOAD_PROVIDER=NVIDIA-G0 --env=__VK_LAYER_NV_optimus=NVIDIA_only --env=LIBVA_DRIVER_NAME=nvidia --env=DESKTOPINTEGRATION=appimaged --noprofile --appimage /home/user/Downloads/CinGG-20230331-x86_64.AppImage

And i can't get Nvidia GPU utilization.
The render runs via CPU.

Here is the information that proves I can run applications through the Nvidia GPU:

export __NV_PRIME_RENDER_OFFLOAD=1
export __GLX_VENDOR_LIBRARY_NAME=nvidia
export __NV_PRIME_RENDER_OFFLOAD_PROVIDER=NVIDIA-G0
export __VK_LAYER_NV_optimus=NVIDIA_only
export LIBVA_DRIVER_NAME=nvidia

I can successfully run apps with Nvidia GPU utilization, e.g. games on Wine.
But CinGG doesn't utilize the Nvidia GPU in Nvidia Prime mode via GPU offload if i run the render via h264_nvenc.mp4 profile
