To add support for WebM, GStreamer needs libvpx packages imported from Fedora.
Created attachment 425485 [details] gas libvpx-0.9.0-6.fc14 (=F-13) - with removed BuildRequires: yasm
Created attachment 425486 [details] Comparison patch. libvpx-0.9.0-6.fc14 adjusted to binary-match (tested only asm .o files) for verification of the gas variant.

BTW upstream has 0.9.1 (+newer GIT); Fedora Rawhide still contains 0.9.0. One should check the upstream patches: * There is a stack non-executability implementation - it may affect SELinux. * There are various backend fixes which may not be immediately visible as the developer's machine chooses a different backend. QA: All the supported optimized backends (MMX/SSE2/SSSE3/etc.) should be probably tested. Post upstream (had to use Midori/webkit, it is Firefox/Gecko-incompatible): http://groups.google.com/a/webmproject.org/group/codec-devel/browse_thread/thread/fb9c3945f26da209
The package was imported into CVS and successfully built.
Red Hat Enterprise Linux 6.0 is now available and should resolve the problem described in this bug report. This report is therefore being closed with a resolution of CURRENTRELEASE. You may reopen this bug report if the solution does not work for you.
