Description of problem: libvpx 1.5.0 has been released see: https://groups.google.com/a/webmproject.org/forum/#!topic/codec-devel/0rjNpFerYs8 It improves both vp9 encoding and decoding performance so would be nice to have it. Unfortunately it breaks ABI so a rebuild of deps will be required.
The break in ABI is reflected by a bump of the soname version. This calls for either a parallel package (libvpx15, or libvpx14 and libvpx), or introduction into the new Fedora release. (But I'm not totally aware of the Fedora update rules on this - just saying.) An entry in the upstream release monitoring database wouldn't be bad either. Let me note that the source URL has moved to http://downloads.webmproject.org/releases/webm/%{name}-%{version}.tar.bz2 (BTW, 1.5.0 seems to build fine with a few SPEC adaptations.)
xpra really benefits from 1.5 for speed, so this would get a vote from me :)
I don't mind doing this in rawhide, but I'm going to have to be convinced to do this for any other branches.
libvpx-1.5.0 is now in rawhide. All dependencies that repoquery found have been rebuilt: http://koji.fedoraproject.org/koji/taskinfo?taskID=12025097
