Is there a known DRM standard (widevine and alikes) using the libva DRM API already ? Is the https://github.com/intel/hdcp project still relevant ?

Also is there a way to demonstrate the DRM functionality (without having a DRM protection standard involved) ?

for now, famous framework ffmpeg has not using va2.11 and newer version ,so demo using libva DRM api may be difficult to find but the pipeline is introduced in many words,you can review it in va_pro.h, in additon, the newest intel opensource driver has not implement DRM api，so I have a lot of doubt that it will be useful even if you use it correctly to do something。
