HW acceleration on an UpBoard
am trying to get ffmpeg HW acceleration on an UpBoard . It uses an Atom x5 z8350 processor and Intel HD 400 GPU
I have also followed this tutorial in order to compile ffmpeg with libmfx enabled.
then ran:
$ ffmpeg -encoders | grep qsv
ffmpeg version 4.1.3 Copyright (c) 2000-2019 the FFmpeg developers
built with gcc 5.4.0 (Ubuntu 5.4.0-6ubuntu1~16.04.11) 20160609

However, when trying to encode I video I am getting:
$ ffmpeg -i in.mp4 -c:v h264_qsv -global_quality 10 -look_ahead 1 out.mp4

What am I missing?
Thank you very much!

Hi @robogil
The feature is enabled specifically using the Intel Media SDK, as you noticed following the linked instructions.
Checking online I found other people having similar issues and depending on the version you are using, I found a solution on the Intel forums: https://software.intel.com/en-us/forums/intel-media-sdk/topic/785168
Please check if that works for you and if not, my suggestion is to open a topic under this section: https://software.intel.com/en-us/forums/intel-media-sdk
