It will be soon 2 years since Google acquires the Widevine company that provides the DRM support for protecting e.g. the HLS H.264/AAC streams.
According to the http://www.widevine.com/ not only Android, but also iPhone/iPad and game consoles like Wii or PS3 ares supported.
Does anybody experience with the Android Widevine DRM?
Regards, STeN
you must be certified by google to work with the Widevine APIs. the certification is called CWIP and requires paying a substantial sum and going through a course.
