Comment (by Balling):

 We do not support limited range RGB, it is an open issue. #1851

 (It is prohibited in the code.)

 >confine the range of the rgb24 pixels to 16 - 235 using lutrgb.

 Why do you do this anyway?

 Second of all, lossy x264 will create files not perfect and containing out
 of the needed range values. Use lossless x264 with -qp 0.
