I have three 15.10 systems with Google Chrome installed. Two play purchased Amazon movies just great. One gives me a "Digital Rights Error" tells me to enable Widevine and refer to error 7235. I think this is a problem with Chrome DRM, not with Amazon because the test video here won't play on the problem system either (it plays great on the working systems): http://www.dash-player.com/demo/drm-test-area/
I did a quick look through my packages and I've got chromium-codecs-ffmpeg-extra, gstreamer-ugly, and similar packages all installed. I've tried:
- Installing, then uninstalling mjblenner's zombie hal package
- Signed in and signed out of my Google account in Chrome
- Forcing the user to sign in to the Ubuntu desktop, or allowing it to log in without signing in
- Logging out of my Google account in Chrome, deleting all data from the Settings windows, uninstalling chrome, deleting ~/.config/google-chrome, then re-installing chrome.
The only other difference between the working systems and the non-working systems is that the Chrome version number says
on the working systems and
on the system that doesn't play DRM.
