If you prefer using Epiphany web browser on Ubuntu 12.04, you may get watching youtube flash videos problem. Here’s a way to get your adobe flash plugin for Firefox working with Epiphany.

First, install adobe flash plugin. Here’s a simple guide installing it on Ubuntu 12.04.

Then install nspluginwrapper with this command:

sudo apt-get install nspluginwrapper

use nspluginwrapper to wrap libflashplayer.so

sudo nspluginwrapper -i /usr/lib/flashplugin-installer/libflashplayer.so

and finally:

nspluginwrapper -v -a -n -i

Now, restart Epiphany and 32-bit flash plugin should work.

64-bit flash plugin read this post on forums.debian.net

Well, it sounds like nspluginwrapper doesn’t like the fact that libflashplayer.so is 64 bit. Its nominal use is to wrap a 32 bit libflashplayer.so for use in a 64 bit browser. It should work if you just grab a 32 bit libflashplayer.so from adobe, though it would be nice not to have to do that. Is nspluginwrapper really limited to wrapping 32 bit plugins?
