emberwave outside Rust: a player in the browser, published at https://with-developer.github.io/emberwave/, and a C API with prebuilt libraries for Linux, macOS and Windows.

Added

  • A browser player (#15): crates/emberwave-web and the page in web/, published to GitHub Pages, decode .pwv1 files with WebGPU in the page and draw them on a canvas.
  • Decoder::encode_rgb records a decode into the caller's command encoder without waiting, and Decoder::rgba_buffer gives the picture; GpuContext::from_adapter creates a context on an adapter the caller chose. Together they let a player keep the picture on the GPU, and they are what the browser player uses.
  • A C API (#16): crates/emberwave-ffi with the header include/emberwave.h, made by cbindgen. Contexts and decoders, packets pushed as they arrive, and the decoded planes or RGB written into the caller's memory; status codes with a message per thread, and panics caught at the boundary. Each release ships the header with a shared and a static library for Linux, macOS and Windows, and a C example decodes every test vector in CI on all three.
  • Decoder::clear, Decoder::start_of_frame and Decoder::lost, which the C API needed.

Changed

  • GpuContext::new, which blocks, is not part of the WebAssembly build; use GpuContext::new_async or GpuContext::from_adapter there.
  • A Decoder destroys its GPU buffers when it is dropped. Native wgpu freed them then anyway; in a browser they waited for the garbage collector. A clone of the buffer from Decoder::rgba_buffer does not keep it alive.
