These instructions apply to the CEF (Chrome) engine in ZennoPoster version 7.6.1 and above.

To be able to use the Widevine component, perform the following steps:

  1. It is necessary to download the plugin file (both cases described below are for x64):

    1. You can get the latest version at this URL.

    2. Extract the .crx file with any ZIP-archiver (e.g. 7-zip) to a folder with name WidevineCdm

    3. Alternative option: this folder can be copied from Google Chrome installation (Program Files\Google\Chrome\Application\X.X.X.X\WidevineCdm). But plugin compatibility is guaranteed only for a narrow set of versions, so option (a) is preferable.

  2. Then, the WidevineCdm folder must be copied to a folder where libcef.dll file is, e.g. C:\Program Files\ZennoLab\EN\ZennoPoster Pro V7\7.6.1.0\Progs\x64

  3. By default, the components are disabled in CEF (Chrome), that is why --component-updater=initial-delay=100000 argument has to be added to CEF (Chrome).
    In this case, initial-delay is the time, in seconds, after which the first attempt will be made to check for updates to the component. Since the component is already present, this check is unnecessary, besides, if there is indeed an update, it will download the component into the profile folder, which will increase the size of each profile folder for which the component-updater instance is enabled.

After these steps, Widevine will work in your CEF (Chrome) instance.
