Description of problem: libass's build should add "BuildRequires: yasm" to support assembly instructions to speed up processing on x86 and x86_64. Version-Release number of selected component (if applicable): 0.13.4-2 How reproducible: Steps to Reproduce: 1. rpmbuild -ba libass.spec Actual results: checking for yasm... no configure: WARNING: yasm was not found; ASM functions are disabled. configure: WARNING: Install yasm for a significantly faster libass build. (See: https://kojipkgs.fedoraproject.org/packages/libass/0.13.4/2.fc26/data/logs/x86_64/build.log) Expected results: checking for yasm... yes Additional info: I haven't tested this, this is by pure inspection of the Changelog and build logs. It looks like the binary's assembly code paths are used conditionally on hardware which supports it, according to libass/ass_utils.c, so this change to use yasm should be valid for all supported x86{,_64} hardware.
Thanks for the bug. I'll test if there's any notable difference and if so, apply it with next release.
This bug appears to have been reported against 'rawhide' during the Fedora 27 development cycle. Changing version to '27'.
Ping. This BuildRequires should probably also be guarded per architecture: %ifarch %ix86 x86_64 BuildRequires: yasm >= 1.2.0 %endif I can try to see whether I can benchmark this with ffmpeg's "ass" filter (which uses the library to render an ASS file as an overlay).

Note that libass now uses nasm over yasm as of commit 0ce4c19, so when libass is eventually updated fully (in a future Fedora release I would guess, since there was an ABI change and thus all dependent packages would need to be rebuilt) instead of cherrypicking commits, this will have to change again.
