CefRuntimeCefRegisterWidevineCdm Method

Register the Widevine CDM plugin. The client application is responsible for downloading an appropriate platform-specific CDM binary distribution from Google, extracting the contents, and building the required directory structure on the local machine. The CefBrowserHost::StartDownload method and CefZipArchive class can be used to implement this functionality in CEF. Contact Google via https://www.widevine.com/contact.html for details on CDM download. |path| is a directory that must contain the following files: 1. manifest.json file from the CDM binary distribution (see below). 2. widevinecdm file from the CDM binary distribution (e.g. widevinecdm.dll on on Windows, libwidevinecdm.dylib on OS X, libwidevinecdm.so on Linux). 3. widevidecdmadapter file from the CEF binary distribution (e.g. widevinecdmadapter.dll on Windows, widevinecdmadapter.plugin on OS X, libwidevinecdmadapter.so on Linux). If any of these files are missing or if the manifest file has incorrect contents the registration will fail and |callback| will receive a |result| value of CEF_CDM_REGISTRATION_ERROR_INCORRECT_CONTENTS. The manifest.json file must contain the following keys: A. "os": Supported OS (e.g. "mac", "win" or "linux"). B. "arch": Supported architecture (e.g. "ia32" or "x64"). C. "x-cdm-module-versions": Module API version (e.g. "4"). D. "x-cdm-interface-versions": Interface API version (e.g. "8"). E. "x-cdm-host-versions": Host API version (e.g. "8"). F. "version": CDM version (e.g. "1.4.8.903"). G. "x-cdm-codecs": List of supported codecs (e.g. "vp8,vp9.0,avc1"). A through E are used to verify compatibility with the current Chromium version. If the CDM is not compatible the registration will fail and |callback| will receive a |result| value of CEF_CDM_REGISTRATION_ERROR_INCOMPATIBLE. |callback| will be executed asynchronously once registration is complete. On Linux this function must be called before CefInitialize() and the registration cannot be changed during runtime. If registration is not supported at the time that CefRegisterWidevineCdm() is called then |callback| will receive a |result| value of CEF_CDM_REGISTRATION_ERROR_NOT_SUPPORTED.
