[BUG] QSVEnc doesn't works

[raven-au]

iirc. you need some additional MetaData for HDR10 (or was it HDR10+) like you can add in x265 using '--dhdr10-info <filename>', which QSVEncC doesn't support atm. just setting the colormatrix, colorprim and transfer options never is enough,...

I needed to set the mastering display and sometimes the max-cll option values depending on the metadata present in the movie.
Adding the -hdr option alone might work but I thought signalling empty SIE data would not give a proper presentation so I didn't try that … and in fact didn't even check if that option was present in QSVEncC.

Maybe it was HDR10+, using the above settings, so far (and I've only done a few movies) I thought it was working ok but the presentation might be off, not sure, certainly my Apple TV 4K and my TV change automatically to HDR.

My sons Xbox One X played one movie ok (first one I did which didn't have any SIE settings but played correctly, odd) but now goes to buffering all the time, apparently a known Plex player problem … sigh.
