See the change log for details about ffmpeg. Proprietary formats are not supported due to licensing restrictions.

If flash is sorted then please close this issue. Thanks

You can find PPAPI standalone download link
for windows in this page https://helpx.adobe.com/flash-player/kb/installation-problems-flash-player-windows.html search for Flash Player for Opera and Chromium-based browsers - PPAPI
for os x https://get.adobe.com/flashplayer/download/?installer=FP_17_Mac_for_Opera_and_Chromium_-_PPAPI&standalone=1

After installation on windows go to
C:\Windows\SysWOW64\Macromed\Flash
You should see there pepflashplayer dll
You can copy it over to your soltuion and add the following line to your code
Cef.AddWebPluginPath(@"./pepflashplayer32_21_0_0_197"); // Flash 21.0.0.197
This how you can verify that whomever using your product would have the appropriate Flash version

p.s. the default "Non-PPAPI" Flash version would display a plugin icon and the message
Adobe Flash Player needs your permission to run

@michal1106 Your post come across as being a requirement, so just clarifying that you can simply install the PPAPI Flash Player from Adobe and it will be used by default without manual file copying or setting plugin paths.

for os x https://get.adobe.com/flashplayer/download/?installer=FP_17_Mac_for_Opera_and_Chromium_-_PPAPI&standalone=1

CefSharp only runs on Windows.

This is questionable in terms of licensing as to my knowledge Adobe don't provide a license for distributing just the binary, so whilst you can technically do this, make sure you perform due diligence and check the licensing first. Also you then become responsible for providing security updates.

You can also load the pepflashplayer.dll that's provided by Google Chrome, again I'm not advocating this, it's just technically possible. (Query registry, get Chrome location, load manually).

You have control over Plugin Placeholders, see https://bitbucket.org/chromiumembedded/cef/issues/1708/add-support-for-plugin-placeholders-and

FYI NPAPI support has been removed from Chromium, so be aware that using the older NPAPI Flash Plugin is no longer supported.
