Using Pepper Flash Plugin
Electron supports the Pepper Flash plugin. To use the Pepper Flash plugin in Electron, you should manually specify the location of the Pepper Flash plugin and then enable it in your application.
Prepare a Copy of Flash Plugin
On macOS and Linux, the details of the Pepper Flash plugin can be found by
navigating to chrome://version
in the Chrome browser. Its location and version
are useful for Electron's Pepper Flash support. You can also copy it to another
location.
Add Electron Switch
You can directly add --ppapi-flash-path
and --ppapi-flash-version
to the
Electron command line or by using the app.commandLine.appendSwitch
method
before the app ready event. Also, turn on plugins
option of BrowserWindow
.
For example:
const { app, BrowserWindow } = require('electron')
const path = require('path')
// Specify flash path, supposing it is placed in the same directory with main.js.
let pluginName
switch (process.platform) {
case 'win32':
pluginName = 'pepflashplayer.dll'
break
case 'darwin':
pluginName = 'PepperFlashPlayer.plugin'
break
case 'linux':
pluginName = 'libpepflashplayer.so'
break
}
app.commandLine.appendSwitch('ppapi-flash-path', path.join(__dirname, pluginName))
// Optional: Specify flash version, for example, v17.0.0.169
app.commandLine.appendSwitch('ppapi-flash-version', '17.0.0.169')
app.whenReady().then(() => {
const win = new BrowserWindow({
width: 800,
height: 600,
webPreferences: {
plugins: true
}
})
win.loadURL(`file://${__dirname}/index.html`)
// Something else
})
You can also try loading the system wide Pepper Flash plugin instead of shipping
the plugins yourself, its path can be received by calling
app.getPath('pepperFlashSystemPlugin')
.
Enable Flash Plugin in a <webview>
Tag
Add plugins
attribute to <webview>
tag.
<webview src="https://www.adobe.com/software/flash/about/" plugins></webview>
Troubleshooting
You can check if Pepper Flash plugin was loaded by inspecting
navigator.plugins
in the console of devtools (although you can't know if the
plugin's path is correct).
The architecture of Pepper Flash plugin has to match Electron's one. On Windows, a common error is to use 32bit version of Flash plugin against 64bit version of Electron.
On Windows the path passed to --ppapi-flash-path
has to use \
as path
delimiter, using POSIX-style paths will not work.
For some operations, such as streaming media using RTMP, it is necessary to grant wider permissions to players’ .swf
files. One way of accomplishing this, is to use nw-flash-trust.
