New description:

 libx265 has options: `preset`, `tune`, and `x265-param`. They are not
 documented in doc/encoders.texi.

 This ticket was originally about missing option to adjust --psy-rd x265
 option. That is invalid because there is an undocumented way to adjust it.
 This ticket now acts as a reminder to add more documentation for x265. See
 [comment:2].

 Original bug description:
 x265 supports psycho-visual options since v1.2 (--psy-rd, --psy-rdoq, also
 related is --rd):
 http://x265.readthedocs.org/en/default/cli.html#pycho-visual-options

 ffmpeg should provide a way of passing these options to libx265.

 I'm guessing there are many other missing options too.
