- * \ingroup wrappers
- *
- * `` provides access to `MediaKeySystemAccess` object that
- * allows to query supported codecs and other informations about the system.
- *
- * For example, visit https://www.fit.vutbr.cz/~polcak/jsr/hdcp/ and try a different browser or
- * computer.
- *
- * \see https://w3c.github.io/media-capabilities/ 
- *
- * We provide two modes of protection:
- *
- * 1. Strict approach prevents accessing the API.
- * 2. Farbling approach changes the output to a non-existing codec with 12.5% probability.
