Struct HwAccelDevice 

pub struct HwAccelDevice {
    pub kind: HwKind,
    pub driver: Option<String>,
    pub render_node: Option<PathBuf>,
    pub supported_codecs: Vec<String>,
    pub max_width: u32,
    pub max_height: u32,
    pub supports_hdr: bool,
}

A single hardware-accelerated device discovered during platform probing.

Codec names follow the OxiMedia convention ("h264", "hevc", "av1", "vp9", "vp8", "mjpeg"). Note that OxiMedia’s Green-List-only CodecId does not include H.264/HEVC; those names appear here because VideoToolbox and VAAPI do in fact support them on the underlying OS hardware — they are reported verbatim so callers can decide whether to use them via FFmpeg compat or platform APIs.

Fields

kind: HwKind

Backend kind (VideoToolbox, VAAPI, …).

driver: Option<String>

Kernel-level driver name, if detectable (e.g., "i915", "amdgpu").

render_node: Option<PathBuf>

DRI render node path (Linux only, e.g., /dev/dri/renderD128).

supported_codecs: Vec<String>

Codec names supported by this device.

max_width: u32

Maximum encode/decode width in pixels.

max_height: u32

Maximum encode/decode height in pixels.

supports_hdr: bool

Whether HDR (10-bit, PQ/HLG) is supported.

Implementations

impl HwAccelDevice

pub fn supports_codec(&self, codec: &str) -> bool

Returns true if this device advertises support for codec.

Comparison is case-insensitive.

Trait Implementations

impl Clone for HwAccelDevice

fn clone(&self) -> HwAccelDevice

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HwAccelDevice

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

Formats the value using the given formatter.
