DRM protection

MKPlayer supports Widevine, PlayReady, and FairPlay DRM. You configure DRM by adding a drm property to your MKSourceConfig before calling player.load(). The player selects the first key system supported by the current platform.

To support playback across browsers and devices, it is recommended to provide both a Widevine and a PlayReady configuration. FairPlay applies only to HLS sources on Apple devices.

Prerequisites

You have an initialised MKPlayer instance and a loaded source. See Installation and setup and Loading and playing content.

Configure DRM

Add a drm object to your source configuration. Each key system is optional — include only the ones your licence server supports:

const sourceConfig = {
  title: "Protected Stream",
  hls: "https://my-cdn.com/mysource/hls/index.m3u8",
  dash: "https://my-cdn.com/mysource/dash/manifest.mpd",
  drm: {
    widevine: {
      LA_URL: "https://your-widevine-license-server/license",
      headers: {
        "X-CustomHeader": "custom-value"
      }
    },
    playready: {
      LA_URL: "https://your-playready-license-server/license",
      headers: {
        "X-CustomHeader": "custom-value"
      }
    },
    fairplay: {
      LA_URL: "https://your-fairplay-license-server/license",
      certificateURL: "https://your-fairplay-certificate-url",
      headers: {
        "X-CustomHeader": "custom-value"
      }
    }
  }
};

player.load(sourceConfig);

Widevine and PlayReady options

Both widevine and playready accept the same core properties:

Property	Type	Description
`LA_URL`	`string`	URL of the DRM licence server.
`headers`	`MKHeaders`	Custom HTTP headers sent with licence requests.

PlayReady on smart TVs

Most smart TV platforms require plaintextChallenge and utf8message to be set for PlayReady licence requests to succeed:

playready: {
  LA_URL: "https://your-playready-license-server/license",
  utf8message: true,
  plaintextChallenge: true,
  headers: {
    "Content-Type": "text/xml"
  }
}

FairPlay options

FairPlay requires a certificateURL in addition to the licence server URL. It applies only to HLS sources on Apple devices.

Property	Type	Description
`LA_URL`	`string`	URL of the FairPlay licence server.
`certificateURL`	`string`	URL to the FairPlay certificate. Required.
`headers`	`MKHeaders`	Custom HTTP headers for licence requests.
`certificateHeaders`	`MKHeaders`	Custom HTTP headers for the certificate request.
`prepareContentId`	`function`	Callback to transform the content ID extracted from the HLS manifest before it is sent to the licence server.
`prepareMessage`	`function`	Callback to prepare the licence acquisition message before it is sent.
`prepareLicense`	`function`	Callback to transform the licence response before it is passed to the browser.
`prepareCertificate`	`function`	Callback to transform the certificate response before it is passed to the browser.
`withCredentials`	`boolean`	Send cookies and auth headers with licence requests. Default: `false`.
`licenseResponseType`	`MKHttpResponseType`	Sets an explicit response type for the licence request. Default: `TEXT`.
`useUint16InitData`	`boolean`	Use `Uint16Array` instead of `Uint8Array` for init data. Depends on your FairPlay licence server. Default: `false`.
`maxLicenseRequestRetries`	`number`	How many times to retry a failed licence request. Default: `1`. Set to `0` to disable retries.
`maxCertificateRequestRetries`	`number`	How many times to retry a failed certificate request. Default: `1`. Set to `0` to disable retries.

Common DRM errors

Error code	Meaning
`PLAYER_DRM_FAILED_LICENSE_REQUEST`	The licence request failed. Check that `LA_URL` is correct and that required headers and tokens are present.
`PLAYER_DRM_NO_KEY_SYSTEM`	The current platform does not support any of the key systems in the source config.
`PLAYER_DRM_CERTIFICATE_ERROR`	The FairPlay certificate could not be loaded or parsed. Check `certificateURL`.
`PLAYER_DRM_INIT_DATA_MISSING`	No DRM init data was found in the manifest or segments. Check your stream packaging.
`PLAYER_DRM_RESTRICTED_OUTPUT`	The device cannot securely present the content, for example due to a non-HDCP display.
`PLAYER_NO_DRM_LICENSE_SERVER_URL_PROVIDED`	`LA_URL` is missing or invalid in the DRM config.
