Enum Backend 

pub enum Backend {
    VideoToolbox,
    Vaapi,
    Cuda,
    D3d11va,
}

Hardware decoding backend.

hwdecode only manages hardware decoders — software fallback is out of scope. If no backend in [probe_order] for the current platform can decode a stream, crate::VideoDecoder::open returns crate::Error::AllBackendsFailed and the caller decides how to fall back (e.g. by opening an ffmpeg::decoder::Video directly).

Variants

VideoToolbox

Apple VideoToolbox (macOS, iOS, iPadOS, tvOS, visionOS).

Vaapi

Linux Video Acceleration API (Intel / AMD GPUs).

Cuda

NVIDIA NVDEC via CUDA (Linux / Windows on NVIDIA hardware).

D3d11va

Microsoft Direct3D 11 Video Acceleration (Windows).

Implementations

pub const fn is_vaapi(&self) -> bool

Returns true if this value is of type Vaapi. Returns false otherwise

pub const fn is_cuda(&self) -> bool

Returns true if this value is of type Cuda. Returns false otherwise

pub const fn is_d_3_d_11_va(&self) -> bool

Returns true if this value is of type D3d11va. Returns false otherwise
