For libx265, custom quantization lists can be specified using -x265-params scaling-list='filename' where file has to be "in the HM format" . See http://x265.readthedocs.io/en/default/cli.html#cmdoption-scaling-list

For libx264, it's -x264opts cqmfile='filename' where file is "a JM-compatible file"
