Enum DmaBufInput 

enum DmaBufInput {
    Direct {
        registered: NV_ENC_REGISTERED_PTR,
        mapped: NV_ENC_INPUT_PTR,
        format: NV_ENC_BUFFER_FORMAT,
    },
    Copy,
}

How a cached dmabuf import feeds the encoder.

Direct is the zero-copy case: the mapped frame’s first plane is itself registered and mapped as an NVENC input — as a pitch-linear device pointer or as a CUDA array, per DirectPlane — so encoding reads the capture buffer in place. Copy covers the rest: a plane direct_plane rules out, one the driver declined to register, or the direct path switched off; the plane is then copied into the session’s packed input surface each frame.
