    38 ~~An assembler for x86 optimizations used by some libraries. Highly recommended or your resulting build may be very slow.~~

    40 Note: Yasm was last updated in 2014 and is insufficient for the latest version of x264. It's recommended to use Nasm instead (below), as that is still under active development and is also available now with the BSD license. (licensing was one of the original reasons Yasm was created).
