 I had a link to the specification, but it's dead now.
 Here are a few examples where the min and max values are set to 0 and 1,
 which are the default values:
 https://forum.blackmagicdesign.com/viewtopic.php?f=21&t=40284

 By the way, in the above link is also described that 1D- and 3D-LUTs can
 be specified in the same *.cube file, and in this case the 1D LUT is
 applied before the 3D LUT. Is this feature implemented in FFmpeg?

 It seems logical to me that min and max can also be set to other values
 than 0 and 1. Otherwise the LUT_1D_INPUT_RANGE option is useless.
