Important notes:
|
||
|
|
<ul>
|
||
|
|
<li>Clearkey support is built in and should always be enabled.</li>
|
||
|
|
<li>Widevine support requires CDM binaries that must be downloaded from Google. Contact Google <a href="https://www.widevine.com/contact.html">here</a> for details.</li>
|
||
|
|
<li>Widevine support is enabled by calling the CefRegisterWidevineCdm() function. See comments in cef_web_plugin.h for usage.</li>
|
||
|
|
<li>The CefRegisterWidevineCdm() function can be called during runtime on Windows and OS X to register Widevine binaries. Use the below form to test this capability.</li>
|
||
|
|
<li>Calling CefRegisterWidevineCdm() before CefInitialize() is required on Linux.</li>
|
||
|
|
<li>Cefclient will call CefRegisterWidevineCdm() before CefInitialize() if "--widevine-cdm-path=<path>" is specified on the command-line.</li>
|
||
|
|
<li>View extended media support information <a href="https://shaka-player-demo.appspot.com/support.html">here</a>.</li>
|
||
|
|
<li>Test DRM video playback <a href="https://shaka-player-demo.appspot.com/demo/">here</a>. Select an "asset" that includes Clearkey or Widevine in the name.</li>
