Enum Backend 

pub enum Backend {
    Auto,
    Nvenc,
    Vaapi,
    Software,
}

Available on crate feature video only.

Which encoder to use. Backend::Auto picks the first available, preferring hardware (NVENC, then VAAPI) over the software fallback.

Variants

Auto

Choose the best available backend at runtime.

Nvenc

NVIDIA NVENC (h264_nvenc). Takes CPU frames; uploads internally.

Vaapi

VAAPI (h264_vaapi) on a DRM render node. Uses a hardware frame pool.

Software

Software libx264. Always works; uses the CPU.

Trait Implementations

impl Clone for Backend

fn clone(&self) -> Backend

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Backend

impl Debug for Backend

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Backend

impl PartialEq for Backend

fn eq(&self, other: &Backend) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
