The reason appears only flash player issues in Chromium:
this is the only problem occurred in Chromium reason is that Chromium before using Netscape Plugin API framework to support Flash, starting from Ubuntu 14.04, Chromium will stop using the Netscape Plugin API. Therefore, we have problems of Chromium of Adobe Flash Player.
So why this problem does not occur in other browsers? The answer is because they use Flash Player 11.2.
Fix the problem on the Chromium Adobe Flash Player:
fix this problem, we should use the Pepper Flash Player, Google from a safer and more stable version of Flash Player. There are Adobe Flash Player Pepper installed at the source Ubuntu 14.04's. The installer will download Google Chrome, then extracted Pepper Flash Player settings to Chromium to use.
To install Ubuntu 14.04 Pepper Flash Player, open a terminal, use the following command:
sudo install pepperflashplugin APT-GET-nonfree
sudo Update-pepperflashplugin-nonfree --install
restart Chromium later. Without restarting the system. I hope this post will help you solve the Adobe Flash Player on the Chromium issue. We welcome any questions and suggestions.
