[FFmpeg-user] -x265-params me=umh is working?

[George Nistor]

Hello,

I have the folowing problem I trie to understand.
I use the folowing command line with the option for x265 as: -x265-params me=umh:
which is Uneven MultiHexagon
  
"D:/apps/avanti/Avanti-ffmpeg-GUI-093/ffmpeg/ffmpeg_avanti.exe" -hide_banner -i "E:/iso/m2ts/dune/Video/DUNE DISC 1/DUNE_DISC_1.Title1010.m2ts" -threads:v 4 -sws_flags lanczos -vf "scale=0:0,setdar=16/9" -codec:v libx265 -b:v 4250k -x265-params me=umh:merange=32:bframes=4:subme=4:open-gop=1:keyint=250:min-keyint=25:asm=SSE,SSE2,SSE3,SSSE3,SSE4,SSE4.1,SSE4.2,FMA3,FMA4 -tune fast-decode -preset ultrafast -codec:a copy "G:/george/mkv/DUNE_DISC_1.Title1010.mp4" 

after encoding I end up wit this metadata copied from MediaInfo tool:
how come is not umh Uneven MutiHexagon  - Motion estimation algo option set up in the destination.
It is not available? Where is the problem here?

I build the command with Avanti tool + a script
