Testing Widevine CDM
In Electron you can use the Widevine CDM library shipped with Chrome browser.
Getting the library
Open chrome://components/ in Chrome browser, find Widevine Content Decryption Module
and make sure it is up to date, then you can find the library files from the
application directory.
On Windows
The library file widevinecdm.dll will be under
Program Files(x86)/Google/Chrome/Application/CHROME_VERSION/WidevineCdm/_platform_specific/win_(x86|x64)/
directory.
On MacOS
The library file libwidevinecdm.dylib will be under
/Applications/Google Chrome.app/Contents/Versions/CHROME_VERSION/Google Chrome Framework.framework/Versions/A/Libraries/WidevineCdm/_platform_specific/mac_(x86|x64)/
directory.
Note: Make sure that chrome version used by Electron is greater than or
equal to the min_chrome_version value of Chrome's widevine cdm component.
The value can be found in manifest.json under WidevineCdm directory.
Using the library
After getting the library files, you should pass the path to the file
with --widevine-cdm-path command line switch, and the library's version
with --widevine-cdm-version switch. The command line switches have to be
passed before the ready event of app module gets emitted.
Example code:
const { app, BrowserWindow } = require('electron')
// You have to pass the directory that contains widevine library here, it is
// * `libwidevinecdm.dylib` on macOS,
// * `widevinecdm.dll` on Windows.
app.commandLine.appendSwitch('widevine-cdm-path', '/path/to/widevine_library')
// The version of plugin can be got from `chrome://plugins` page in Chrome.
app.commandLine.appendSwitch('widevine-cdm-version', '1.4.8.866')
let win = null
app.on('ready', () => {
win = new BrowserWindow()
win.show()
})
Verifying Widevine CDM support
To verify whether widevine works, you can use following ways:
- Open https://shaka-player-demo.appspot.com/ and load a manifest that uses
Widevine. - Open http://www.dash-player.com/demo/drm-test-area/, check whether the page
says
bitdash uses Widevine in your browser, then play the video.
