It works for VVenC. As for works, i mean that i can enter the container with /bin/bash, execute ffmpeg -codecs | grep vvc and this is the response:

 DEV.L. vvc                  H.266 / VVC (Versatile Video Coding) (encoders: libvvenc)

But for libx265 it's not working.

ffmpeg -codecs | grep x265 

In another try:

ffmpeg -codecs | grep 265
 DEV.L. hevc                 H.265 / HEVC (High Efficiency Video Coding) (decoders: hevc hevc_v4l2m2m) (encoders: hevc_v4l2m2m)

After i enter the ffmpeg directory again and execute make install it works.

root@0a2ad1086abd:/usr/local/src# cd ffmpeg
root@0a2ad1086abd:/usr/local/src/ffmpeg# make install
... installation logs ...

Is there anything i can do here? I tried separating layers, unifying... I really don't know what else should i do.

I was being way too dumb. As i was using volumes, in one of my tests i cloned ffmpeg into my system. This was replicating it inside the container (which was why it was working when inside container).

I got no errors or anything because docker was using a cached image (one of the first versions). I deleted it and rebuilt, then it started to blame the problems i had. I adjusted the builds to be in same layer again and then built it, then it started to work.

If you find yourself lost like i was, try pruning the images. I was using --no-cache but for some reason it was still caching the old file.

Also a tip, cmake uses -DCMAKE_INSTALL_PREFIX not the prefix path like i used in the question

-DCMAKE_INSTALL_PREFIX=/usr/local

So this also helped
