DxFilter

docs.rs Crates.io Crates.io

Scale and ColorConversion done with DirectX filters. You can also create your own filters with the provided api.

Crate contains various tools to make these features possible.

  • generate_shader! and compile_shader! macros to write shaders that compile at compile time
  • various built filters for converting and scaling from RGB to YUV or NV12
  • DxFilter interface for writing custom filters
  • utils like create_device_context , create_input_tex, create_output_tex for easier setup.
  • utils like AdapterFactory, Adapter, TextureReader imported from win_desktop_duplication.

For example usage, look at examples/rgb_to_nv12.rs

Usage

// for more detailed example see examples/rgb_to_nv12.rs
fn main() {
    // {...}

    //                                    Texture    Texture    directx device
    let filter = ConvertARGBToNV12::new(&input_tex, &output_tex, &device).unwrap();
    //                directx device
    filter.apply_filter(&context).unwrap();

    // { ... }
}
