Struct YuvUploadNode 

pub struct YuvUploadNode {
    pub format: YuvFormat,
    pub width: u32,
    pub height: u32,
    /* private fields */
}

Upload raw YUV plane buffers to the GPU and convert to RGBA in a fragment shader, bypassing CPU-side sws_scale.

The node has input_count() = 0; it sources all pixel data from the plane buffers set via YuvUploadNode::set_planes. Call set_planes once per frame before the graph processes it.

Fields

format: YuvFormat

Pixel sub-sampling format.

width: u32

Frame width in pixels.

height: u32

Frame height in pixels.

Implementations

impl YuvUploadNode

pub fn new(format: YuvFormat, width: u32, height: u32) -> Self

Create a new node. Plane buffers are initialised to neutral values (Y = 0, Cb = Cr = 128).

pub fn set_planes(&mut self, y: Vec<u8>, cb: Vec<u8>, cr: Vec<u8>)

Replace the stored plane buffers.

Expected sizes for width × height at format:

• y: width × height bytes
• cb, cr: chroma_w × chroma_h bytes (sub-sampled per YuvFormat)

Trait Implementations

impl Default for YuvUploadNode

fn default() -> Self

Returns the “default value” for a type.

impl RenderNode for YuvUploadNode

Available on crate feature wgpu only.

fn input_count(&self) -> usize

Number of input textures required by this node (default: 1).

fn process( &self, _inputs: &[&Texture], outputs: &[&Texture], ctx: &RenderContext, )

Run the GPU render pass.

fn pass_count(&self) -> usize

Number of render passes (default: 1). Multi-pass nodes (e.g. gaussian blur) return 2 or more.

impl RenderNodeCpu for YuvUploadNode

fn process_cpu(&self, rgba: &mut [u8], w: u32, h: u32)

Process rgba in-place.
