ASRock H97 Pro4にXeon E3-1265L v3を載せたHaswellでQSVなハードウェアエンコードをお試し。

2017年に通った道だが、まずは最新版のUbuntu 20.04(FocalFossa) Serverを導入。

続いて「Intel® Media SDK」を入れればいいのかぁな…と思ったのだが、2013年生まれのHaswellは古すぎるので、Video Acceleration API(VAAPI)を使えということらしい。

root@haswell:~# apt install -y build-essential libva2 vainfo i965-va-driver

で導入し、

となればVideo Acceleration API(VAAPI)の準備OK。
