# Project Hints and Findings
## Mediabunny / @types/dom-webcodecs Override (2026-04-12)
The `mediabunny` package depends on `@types/dom-webcodecs` and `@types/dom-mediacapture-transform`, which conflict with TypeScript 6's built-in WebCodecs types in `lib.dom.d.ts`. We override both via `pnpm.overrides` in `package.json`, pointing them to local stubs in `ts_web/types/`:
- `dom-webcodecs-stub/` — empty, since TS6 provides these types natively
- `dom-mediacapture-stub/` — provides `MediaStreamVideoTrack` and `MediaStreamAudioTrack` interfaces (not yet in `lib.dom.d.ts`)
If mediabunny drops these `@types` dependencies in a future version, the overrides can be removed.
