Description
Windows / Mac
A system-wide installation of Pepper Flash that will be automatically discovered and loaded by CEF on Windows and OS X can be downloaded from adobe.com - choose "FP for Opera and Chromium -- PPAPI" in Step 2:

After installation to enable pass the --enable-system-flash command-line argument (this is a CEF switch). In CEF Python you can set command line switches programmatically, see api/CommandLineSwitches.md.
You could also specify PPAPI flash plugin from Google Chrome installation using --ppapi-flash-version and --ppapi-flash-path switches. Example path would be: "C:\Program Files (x86)\Google\Chrome\Application\47.0.2526.106\PepperFlash\pepflashplayer.dll". Note that Google Chrome version and CEF Python version should match - when using eg. cefpython v57 use pepper flash from Google Chrome v57.

Linux
Adobe does not provide a system-wide install of the Pepper Flash plugin on Linux. To load the plugin included with Google Chrome:
- Install a version of Google Chrome that is close to the CEF version.
- Specify the Flash library path and version via the command-line. The version number
can be identified by viewing the manifest.json file in the same directory as libpepflashplayer.so.
cefclient --ppapi-flash-version=17.0.0.141 --ppapi-flash-path=/opt/google/chrome-unstable/PepperFlash/libpepflashplayer.so
In CEF Python you can set command line switches programmatically, see api/CommandLineSwitches.md.
