[SOLVED] FFMPEG - Failed to initialise VAAPI connection

I'm trying to encode video file into smaller format using ffmpeg. My CPU is i7-6500 and should have VAAPI. This is the command line used:

ffmpeg -threads 1 -i cc2.mp4 -vaapi_device /dev/dri/renderD128 -vcodec h264_vaapi -vf format='nv12|vaapi,hwupload' output.mp4 

ffmpeg version 3.2.2 Copyright (c) 2000-2016 the FFmpeg developers

[AVHWDeviceContext @ 0x5555df5665c0] Failed to initialise VAAPI connection: -1 (unknown libva error).
[vaapi @ 0x5555df31acd0] Failed to create a VAAPI device

I barely understand what is going on to be honest, my end goal is encode video in decent enough quality (and have some sense how can I tweak quality vs speed vs size) and using integrated intel GPU acceleration to achieve that goal (or whatever makes it the fastest, simple as that)

Re: [SOLVED] FFMPEG - Failed to initialise VAAPI connection

In my case I had to install `intel-media-driver`.
