Enum Device 

#[non_exhaustive]
pub enum Device {
    Auto,
    Cuda(u32),
    Vulkan(u32),
}

Which GPU to run on.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Auto

Vulkan device 0 (else CUDA device 0).

Cuda(u32)

A CUDA device, with the Vulkan device derived from it so decode, processing and encode share one physical GPU regardless of Vulkan enumeration order. No Vulkan video encode.

Vulkan(u32)

A Vulkan physical device index, with CUDA (NVENC) derived from it.
