Hi, thank you for you work on this niche problem. I'm running Chromium 46.0.2490.86 (64-bit) and widevinecdm-plugin 19.0.0.226-1 As explained on my first comment, checking chrome://plugins or chrome://extentions does not lists any widevinecdm stuff. If you uploaded a new version of the plugin on the packman servers I need to wait my repo to sync.
