 that's not what i mean, is just the contrary. I want to avoid MT and use
 only one core.

 I've tested making my own ffmpeg build in a clean Debian installation and
 this script: https://github.com/rdp/ffmpeg-windows-build-helpers and got
 the same problem.

 I've done some test with this command line:

 % ffmpeg.exe -threads 1 -i in.mp4 -c:v libx264 out.mp4
 % ffmpeg.exe -threads 1 -i in.mp4 -c:v libx265 out.mp4

 With both builds (Zeranoe and mine) and both commands, i've got the same
 problem with -threads option: it uses both threads instead only one.

 I'll try an older build, because maybe is a problem of lastest build.
