[FFmpeg-user] Initialising hardware device fails with error -17

[Martin Stenzel]

Hi Haihao,

this is an update finding myself in a happy mood 🙂

openSuSE ships both _libmfx_, and _libmfx-gen_.

It took me some time to realise that, but your last response lead me in the

right direction. I compiled libmfx-gen, and voila I can qsv transcode as 
desired.

Thank you for your continuous support,


Martin.
