Struct HardwareEncodeDevice 

pub struct HardwareEncodeDevice { /* private fields */ }

The renderer’s device, as a hardware encoder can use it.

Implementations

impl HardwareEncodeDevice

pub const fn vulkan(context: SharedVulkanContext) -> Self

The shared Vulkan device the renderer runs on.

pub fn capability( &self, codec: NativeVideoCodec, ) -> Result<HardwareEncodeCapability, String>

What this device’s hardware encoder accepts for codec.

A device can encode one codec and not another, so each export asks about its own. Linux and macOS have one hardware encoder, for H.264.

Errors

Says why this device has no usable hardware encoder for codec.

pub fn preferred_capability(&self) -> Result<HardwareEncodeCapability, String>

The capability a report leads with: on Windows the first of H.264, HEVC and AV1 this device encodes, elsewhere the one encoder there is.

Errors

Says why this device has no usable hardware encoder at all.

pub fn open( &self, request: &HardwareEncodeRequest<'_>, ) -> Result<(HardwareEncodeSession, HardwareEncodeInput), HardwareEncodeOpenError>

Opens a session writing request.output and its input half.

Everything that can refuse does so before the output file exists.

Errors

HardwareEncodeOpenError::Refused before any output exists, HardwareEncodeOpenError::Failed once creating it went wrong.
