I have to install libaom from Git since its last tag is from a couple years ago and it no longer builds (bug #681064). Since that tag, they dropped alpha channel definitions which VLC is trying to use. VLC fixed it upstream a few weeks ago, so can that fix be backported? https://github.com/videolan/vlc/commit/595878cddd1b9b2ba6706a3782011e9228c64876 Reproducible: Always Steps to Reproduce: 1. emerge vlc # with the libaom live ebuild installed Actual Results: The build fails from AOM_IMG_FMT_444A not being defined. Expected Results: The build should succeed.
Fix is included in vlc-3.0.10 which is now available in Gentoo repository.
