   	To answer my own question, I just noticed that when launching   
   ffmpeg it prints out the following:   
      
     configuration: --prefix=/usr --libdir=/usr/lib64 --shlibdir=/usr/lib64   
   --docdir=/usr/doc/ffmpeg-4.4.1/html --mandir=/usr/man --disable-debug --   
   enable-shared --disable-static --enable-gpl --enable-version3 --enable-   
   avresample --arch=x86_64 --disable-encoder=aac --enable-libfontconfig --   
   enable-libfreetype --enable-libfribidi --enable-gnutls --enable-libbluray   
   --enable-libcaca --enable-libcdio --enable-frei0r --enable-openal --   
   enable-libopus --enable-libspeex --enable-libssh --enable-libtheora --   
   enable-libv4l2 --enable-libvidstab --enable-libvorbis --enable-libvpx --   
   enable-libwebp --enable-libmp3lame --enable-opencl --enable-opengl --   
   enable-libopenjpeg --enable-libpulse --enable-libsmbclient --enable-   
   libxml2 --enable-librsvg --enable-libdrm   
      
   	So, no x264 support :-( I'll try to build it with x264 support.
