Notes

• While testing this out, I installed and removed libhal1-flash, pepperflashplugin-nonfree. I am not sure if that did the trick. But now it works in google chrome even without them.

• Even with libhal1-flash, pepperflashplugin-nonfree installed, Amazon video does not work in chromium and iceweasel. I still get the above errors.

• To install the pepperflashplugin-nonfree package

 sudo apt-get install pepperflashplugin-nonfree

• To install the libhal1-flash

Add the following lines to /etc/apt/sources.list

 deb http://www.deb-multimedia.org jessie main non-free

Update the package list

 sudo apt-get update

Install the libhal1-flash package

 sudo apt-get install libhal1-flash
