Crate vtsampler 

Cross-platform GPU video format conversion and scaling (wgpu compute).

Public API: one VTImage in, one VTImage out via VTSampler::process or VTSampler::encode. CPU pixels and render-target textures are handled internally with a scratch pool to avoid extra copies when GPU usages already match.

Modules

bridge

Platform texture bridges (D3D11 / CVPixelBuffer+Metal → wgpu).

Structs

PipelineKey

VTImage

User-facing “one image” (format + size + backing).

VTImageOwned

GPU image allocated by crate::VTSampler::allocate.

VTProcessOptions

VTSampler

GPU video convert + scale engine (one input image → one output image per call).

VTSamplerBuilder

Builds a VTSampler on a shared or external GPU device.

Enums

PixelData

CPU-side pixel payload referenced by crate::VTImage.

VTColorSpace

YUV/RGB matrix selection for conversion shaders.

VTFormat

Logical pixel format for conversion and scaling.

VTSampleError

Errors surfaced by the conversion pipeline.

VTScaleFilter

Filtering used when input and output dimensions differ.

VTTextureRole

Describes how a GPU texture participates in a process pass.
