eme-encryption-scheme-polyfill
Advanced tools
A polyfill to add support for EncryptionScheme queries in EME and MediaCapabilities.
Because this polyfill can't know what schemes the UA or CDM actually support, it assumes support for the historically-supported schemes of each well-known key system.
In source form (index.js), this is compatible with the Closure Compiler and
the CommonJS module format. It can also be directly included via a script tag.
The minified bundle (dist/eme-encryption-scheme-polyfill.js) is a standalone
module compatible with the CommonJS and AMD module formats, and can also be
directly included via a script tag.
The v2.0.3 build is about 5.3kB uncompressed, and gzips to about 1.7kB.
To avoid the possibility of extra user prompts, this will shim EME & MC so long
as they exist, without checking support for encryptionScheme upfront. The
support check will happen on-demand the first time EME/MC are used.
npm install eme-encryption-scheme-polyfill
<script src="node_modules/eme-encryption-scheme-polyfill/dist/eme-encryption-scheme-polyfill.js"></script>
// Install both EME & MC polyfills at once:
EncryptionSchemePolyfills.install();
// Install each one separately (unminified source only):
EmeEncryptionSchemePolyfill.install();
McEncryptionSchemePolyfill.install();
