CefRegisterWidevineCdm 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 StartDownload(String) method class can be used to implement this functionality in CefSharp. 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 Windows). 3. widevidecdmadapter file from the CEF binary distribution (e.g. widevinecdmadapter.dll on Windows). If any of these files are missing or if the manifest file has incorrect contents the registration will fail and callback will receive an ErrorCode value of IncorrectContents. 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 an ErrorCode value of Incompatible. If registration is not supported at the time that Cef.RegisterWidevineCdm() is called then callback will receive an ErrorCode value of NotSupported.
