Microsoft released PlayReady in 2008 and it’s one of major DRM systems out in the market with broad device support, sophisticated features and has been used at scale already by many events such as the Olympics in Sochi, Russia. The Bitmovin encoding service supports PlayReady encryption and packaging with MPEG-CENC. The Bitmovin player plays PlayReady encrypted videos on platforms that support the PlayReady DRM natively in HTML5 without plugins.
This tutorial is based on this full example, which is using our Bitmovin PHP API client, however we do offer API clients in other languages as well. If you haven't created any encodings with our API clients yet, we recommend you to read the getting started guide called "Create an Encoding with our API" at first, before you continue.
Lets start with the preparation of required information we need in order to protect your content using Playready DRM. This values will be provided by your multi DRM licensing server provider such as Irdeto, EZDRM, ExpressPlay, Axinom, etc.
1$key = "0123456789abcdef0123456789abcdef";2$kid = "0123456789abcdef0123456789abcdef";3$playreadyLaUrl = "https://example.com/playready-la-url";
The parameters of the configuration have the following meaning:
- key: This is the common content encryption key
- kid: This is the common unique identifier for your content key in hex format
- playreadyLaUrl: This is the URL to the PlayReady license server
We will use this information to create a CENC DRM resource, which will be created for each fMP4 Muxing you want to be encrypted and protected with PlayReady DRM. Further we have to provide a output location, where those encrypted segments should be stored at. Therefore, we don't provide the output location with the fMP4 Muxing, but with the CENC DRM resource instead.
1$fmp4Muxing1080p = createFmp4Muxing($apiClient, $encoding, $videoStream1080p, null, null);2$audioFmp4Muxing128 = createFmp4Muxing($apiClient, $encoding, $audioStream128, null, null);34$cencDrmEncodingOutput1080p = createEncodingOutput($s3Output, $outputPath . 'video/1080p/dash/drm/');5$cencDrm1080p = createCencDrm($cencDrmKey, $cencDrmKid, array($cencDrmEncodingOutput1080p), null, $playreadyLaUrl);6$videoFmp4Drm1080p = $apiClient->encodings()->muxings($encoding)->fmp4Muxing()->drm($fmp4Muxing1080p)->cencDrm()->create($cencDrm1080p);78$audioCencDrmEncodingOutput128 = createEncodingOutput($s3Output, $outputPath . 'audio/128kbps/dash/drm/');9$audioCencDrm128 = createCencDrm($cencDrmKey, $cencDrmKid, array($audioCencDrmEncodingOutput128), null, $playreadyLaUrl);10$audioFmp4Drm128 = $apiClient->encodings()->muxings($encoding)->fmp4Muxing()->drm($audioFmp4Muxing128)->cencDrm()->create($audioCencDrm128);
Hint: If you would provide a output location for the muxing as well, our API would store unencrypted segments to the given output location as well.
