How to enable gpu acceleration on flatpak ?

[bitcoin1192]

i would like to use tensor acceleration on nvidia gpu, but i couldn't figure out how to install needed runtime for tensor rt with flatpak. i think cuda is available in flatpak obs ? because i am able to encode with nvenc. if its not possible, is there any gpu acceleration alternative i could use on flatpak ?

CUDA is not available on Flatpak. No GPU acceleration will be provided on Flatpak because it is technically impossible on Flatpak.

NVENC working in Flatpak does not mean the plugin can use CUDA or TensorRT. Those are separate stacks. In practice, Flatpak OBS is usually the wrong route for this plugin if you want NVIDIA acceleration, because the TensorRT and CUDA libraries the plugin needs are not exposed cleanly inside the sandbox. The fix is to use a native OBS install and install the plugin there. That is the setup people use when they want the GPU path to work reliably.

We'd like to write a simple guide to install OBS and our plugin natively for those who need GPU-accelerated background removal. I'm down when I'm free.

Yeah... i was a bit confused because some flatpak did have cuda acceleration, as far as i remember blender does, at least in fedora. This also apply to other onnxruntime ep like rocm right ?

idk but not feasible for us
