[Bug/Feature Request/Simple Fix] Widevine CDM Adapter does not work with vivaldi. (netflix support)
libwidevinecdmadapter.so can be loaded using [code]vivaldi --register-pepper-plugins="/opt/vivaldi/libwidevinecdmadapter.so#Widevine Content Decryption Module#Enables Widevine licenses for playback of HTML audio/video content. (version: 220.127.116.111)#18.104.22.1681;application/x-ppapi-widevine-cdm"[/code] however this doesn't properly decrypt content for playback due to some minor incompatabilites with the chromium base, this can be fixed in chromium by following the guide [url=https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1371274/comments/24]here[/url] so a similar fix should be fairly easy in vivaldi.
I glanced at your link and as simple as that looks, it might be a good idea to post a bug report if you haven't already.
