using cuvid in hwaccell ffmpeg

[Mimo]

I did send you a link to a dev version which allows to set 'cuvid' in ffmpeg hwaccel settings.
-> Did you test it?

yes, working fine, but my GPU is not able to decode HEVC even with cuvid (860M feature set E - hybrid decoding) :

FFmpeg : cuvid hwaccel requested for input stream #0:0, but cannot be initialized.

but thanks ...

looks like cuvid is broken in my drivers as even AVC is stopping with same error ...
