Dreams still come true. Thank you very much for this improvement.

I tested it the same way, but I get the error message.

Decoder h264 does not support device type vaapi.
HW device init failed, using SW decode.
  err: Success

Under OpenSuse I installed the following package.
zypper install libva-devel-2.4.0-lp150.114.1.x86_64.rpm

In the Cin settings I have set it to X11. However, I have installed the 
proprietary drivers, do I need to change this?

Thanks again for this implementation.
