// Versioning:
// Until the WebCodecs spec is finalized, the major version number is 0. I have chosen to use minor
// version 1 to denote the API as defined by the IDL files from the Chromium repo at
// https://chromium.googlesource.com/chromium/src/+/main/third_party/blink/renderer/modules/webcodecs.
// Please use a version number above 0.1 if using the spec at https://w3c.github.io/webcodecs/ as
// the source.

// The declarations in webcodecs.generated.d.ts have been generated using the code in
// https://github.com/yume-chan/webcodecs-lib-generator. See
// https://github.com/yume-chan/webcodecs-lib-generator/blob/main/README.md for more detail.
/// <reference path="./webcodecs.generated.d.ts" />

// The following declarations are copied from
// https://github.com/microsoft/TypeScript-DOM-lib-generator/blob/a75338e1ea8a958bf08a5745141d2ab8f14ba2ca/baselines/dom.generated.d.ts
// and modified to expand the types to include VideoFrame.
