Hardware acceleration status

under Linux, as from what I was reading only decoding works not encoding (or the other way around, not sure).

That applied to Nvidia cards. Both NVENC & NVDEC are now supported (Release Notes).

@mkools

And what works on Windows/Linux and what does not?

For Linux:
Intel QSV: Yes
Nvidia: Yes
AMD: No

Hardware Transcoding with AMD Cards?

Until there exists AMD support in the VA-API, there won’t be AMD support. AMD uses MESA making this AMD GPU support very unlikely in the immediate future. Intel QSV and nVidia are the two supported forms at this time.
