# 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://flash` 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:
|
||
|
||
```javascript
|
||
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.on('ready', () => {
|
||
let 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.
|
||
|
||
```html
|
||
<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](https://github.com/szwacz/nw-flash-trust).
