From Chromium 34 (or 35) onwards, NPAPI plugins have no longer supported, including Adobe branded Flash Player. To get the flash movie stuff going, Pepper Flash probably is the only route to go for Chromium but with a lacking feature of playing DRM protected video clip. For playing the DRM stuff on Linux platforms, the approach to run Iceweasel in conjunction with either Adobe Flash Player (v11.2) or Chrome Pepper Flash (v19.0; extracted from ChromeOS) plus freshplayerplugin (ppapi2npapi compatibility layer) is still kind of irreplaceable at the moment.
