Comment:
@Bailing,
I can get it to work with HDR to SDR tone-mapping on NVENC.
The error you're getting comes from the encoder wrapper you're using, not
the filter.
You can specify the correct supported format(s) in the filter directly as
shown in the example(s) below (for the respective NVENC encoder wrappers):
'''HDR to SDR linear Tonemap, to 8-bit H.264'''

I'll be testing this later on with QuickSync and VAAPI.
