VP9 encoding support on Windows

Hello,

I am using the Intel Media SDK for Windows and encounter issues when trying to initialize hardware-accelerated VP9 encoding (MFXVideoENCODE_Query returns MFX_ERR_UNSUPPORTED). My setup looks like following:

• Windows 7 64-bit
• Intel Media SDK for Windows 2018 R2
• Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz
• Intel(R) HD Graphics 530  (Version 21.20.16.4860)

Therefore, I would have two questions:

1. Is VP9 encoding supported for this chip?
2. Do I have to load a plugin before I can use the VP9 encoder (similar to the HEVC plugin)?

Thank you very much in advance!
