| This folder contains code to support W3C Encrypted Media Extensions (EME), |
| key systems and Content Decryption Modules (CDM). It's under `//components` |
| folder so they can be shared by multiple embedders of content, e.g. `//chrome` |
| and `//android_webview`. See |
| [`//components` use cases](https://source.chromium.org/chromium/chromium/src/+/main:components/README.md#use-cases) |
| for more context. |
| |
| This means that only content embedders can depend on targets in this folder, |
| including `//chrome`, `//chromecast`, `//android_webview`, `//fuchsia_web`, and |
| `//content/shell` (test content embedder). Other folders, especially `//media` |
| and `//content`, should NOT depend on targets in this folder. |
| |
| In general, key system specific logic should not be in `//media` or `//content`. |
| So it's also a good practice to put them under `//components/cdm`. |
