when encoding

 Some recent x265 options like frame-dup and tune=animation are not passed
 to the libx265 library when encoding, even when passed as key=value after
 -x265-params. I checked that when using an older tune option (by replacing
 animation=1 with psnr=1 or ssim=1) that option gets applied properly, as
 well as any common option.

 How to reproduce:
 {{{
 ffmpeg -i input.mkv -map 0:v:0 -c:v libx265 -x265-params "frame-
 dup=1:animation=1" output.mkv
 }}}
 The output is identical to :
 {{{
 ffmpeg -i input.mkv -map 0:v:0 -c:v libx265 output.mkv
 }}}
 and to:
 {{{
 ffmpeg -i input.mkv -map 0:v:0 -c:v libx265 -x265-params "frame-
 dup=0:animation=0" output.mkv
 }}}

 ffmpeg builds tested:
 {{{
 ffmpeg version N-53260-ga37109d555-static from
 https://johnvansickle.com/ffmpeg/
 built with gcc 8 (Debian 8.3.0-6) for the amd64 architecture
 }}}

 The problem occurs with the latest Git as well as release 4.3, and with
 the static Windows amd64 builds (Git) from
 https://ffmpeg.zeranoe.com/builds/

 The resulting videos all have the same options applied as a default
 encode:
