Hybrid Dev version 2018.05.21.1 Crashes

[Selur]

Failed to parse HEVC HDR10 metadata.

Comes from NVEncC, when it can't parse the maxcll or master-display data.

This you specify this by yourself?
The master display data "--master-display L(10000000,20)" is wrong,it shoud look similar to:

G(13250,34499)B(7499,2999)R(34000,15999)WP(15634,16450)L(10000000,1)

The first part which specifies the RGB values and the white point is missing in your case.
In case you didn't specify this value manually can you share a !small! sample of the source so I can analyze it and see where Hybrid is struggling.
