CEF Forum

Is there is a workaround to enable flash plugin to execute directly, for any origin, without user interaction with chromium 76 ?

What errors do you see? Have you checked Developer Tools console? Are you setting the --plugin-policy=allow switch?

Don't see any errors. But the user have to right click on the Adobe Icon to allow flash player to execute.

You have to set the switch I've mentioned. You can do it in the OnBeforeCommandLineProcessing callback.

Is that switch (plugin-policy) has something to do with the handler OnBeforePluginLoad ?
What if I set:
modifyPolicy = true;
and
plugin_policy=CefRequestContextHandler::PluginPolicy::PLUGIN_POLICY_ALLOW;
in that handler ?

Set *plugin_policy=PLUGIN_POLICY_ALLOW and return true from OnBeforePluginLoad if mime_type "application/x-shockwave-flash".

It's what I did in the cefclient but still have to Right click on the Puzzle icon, each time, to run the flash player plugin:

*plugin_policy = PLUGIN_POLICY_ALLOW;
return true;

It was working fine with CEF 75 and previous but no more with CEF 76...

Maybe the plugin is not up to date? If this is the case, I think there is either a policy or command line flag (or it was) which allowed also outdated plugins.

The plugin is up to date (32.0.0.255) and I tried with --allow-outdated-plugins

See "plugins.run_all_flash_in_allow_mode" preference:

Code: Select all

// Boolean that indicates whether all Flash content (including cross-origin and
// small content) is allowed to run when it is explicitly allowed via content
// settings.
const char kRunAllFlashInAllowMode[] = "plugins.run_all_flash_in_allow_mode";
