Description Arfrever Frehtes Taifersar Arahesis 2019-02-25 05:17:21 UTC
>=media-libs/libvpx-1.8.0 probably should not have "svc" USE flag at all.
Support for SVC is probably enabled unconditionally by upstream.

In ebuilds:
--- libvpx-1.7.0.ebuild
+++ libvpx-1.8.0.ebuild
...
-               $(use_enable svc experimental) $(use_enable svc spatial-svc)
+               $(use_enable svc experimental)


In libvpx source code:
--- libvpx-1.7.0/configure 
+++ libvpx-1.8.0/configure
...

So --enable-experimental is not needed for support for SVC.

Ebuild does not pass any of --enable-fp-mb-stats, --enable-emulate-hardware, --enable-non-greedy-mv, --enable-ml-var-partition options, so there is no need to pass --enable-experimental option.

It is not enabled unconditionally, but removed completly:
