Plugins

CEF Python automatically loads plugins installed on your system, it works similarly to Chrome. To disable loading of plugins you have to set BrowserSettings.plugins_disabled to True for each browser you create.

Both CEF 1 & CEF 3 support NPAPI plugins. CEF 3 supports also PPAPI plugins, but it is not yet fully tested.

To see a list of plugins that are being loaded run cefclient.exe, a test browser that is included in cefpython binary zip, from the menu select Tests > Plugin Info.

Enable Flash Player

To enable Flash player in CEF Python you have to install NPAPI version of Flash in your OS:

1. Go to http://get.adobe.com/flashplayer/otherversions/
2. Select your operating system
3. Select NPAPI version of plugin (for Firefox)

After that run cefclient.exe > Tests > Plugin Info and you should see:

Flash is installed!
Name: Shockwave Flash 
Description: Shockwave Flash 11.5 r502 
Version: 11,5,502,110 
Path: C:\Windows\SysWOW64\Macromed\Flash\NPSWF32_11_5_502_110.dll 

Flash on Linux

Flash plugin will crash on Linux in CEF 1, see Issue 553 in CEF Issue Tracker.

Custom plugins

With CEF you can load custom plugin by providing a path to it. In CEF 1 you can do this through ApplicationSettings.extra_plugin_paths option, but it is not yet implemented in cefpython 1. In CEF 3 there are functions CefAddWebPluginPath() & CefAddWebPluginDirectory() defined in cef_web_plugin.h, but it is also not yet implemented in cefpython 3.

Google Chrome comes with an internal flash player called Pepper Flash Player (a PPAPI plugin), it can be found in "c:\Program Files (x86)\Google\Chrome\Application\23.0.1271.91\PepperFlash", but to be able to distribute it with your app you need a licensing agreement in place with Adobe.

There is an api in CEF for getting info about a plugin, the file is "include/cef_web_plugin.h", it is not yet implemented in cefpython.
