Enum MemoryDomain 

pub enum MemoryDomain {
    System,
    Cuda,
    D3d11,
    D3d12,
}

Where a decoded frame’s pixels actually live.

MediaBuffer::Video is one variant covering system memory, CUDA device memory, and D3D11/D3D12 textures alike, so the buffer type alone cannot tell a CPU scaler that it was handed a GPU texture. This is the part of the contract that catches that — it says which backend owns the memory, and nothing about the format, size, or specific device within that backend.

Variants

System

Host memory: an ordinary FFmpeg frame with CPU-readable planes.

Cuda

CUDA device memory bound to a CUDA context.

D3d11

A D3D11 texture owned by an ID3D11Device.

D3d12

A D3D12 resource owned by an ID3D12Device.
