VTSampler

Cross-platform GPU video format conversion and scaling on wgpu. One VTImage in, one out — similar in spirit to D3D11 Video Processor, but portable.

API reference: docs.rs/vtsampler · Local: cargo doc --open --no-deps

Features

• Formats: RGBA, BGRA, NV12, YUV420P (any → any)
• Scaling when input/output sizes differ
• Color: BT.601 / BT.709 limited range
• Backings: CPU, wgpu textures, D3D11 (Windows), CVPixelBuffer (macOS)

Quick example

use vtsampler::{PixelData, VTFormat, VTImage, VTProcessOptions, VTSamplerBuilder};

# async fn run() -> Result<(), vtsampler::VTSampleError> {
let mut sampler = VTSamplerBuilder::default().build().await?;

let input = VTImage::from_cpu(&pixel_data, 1920, 1080);
let output = VTImage::from_render_target(&gpu_texture, VTFormat::BGRA);

sampler.process(&input, &output, VTProcessOptions::default())?;
# Ok(())
# }

Share your renderer's device with VTSamplerBuilder::with_arc_device.
