I'm not completely sure of the relationship between libvpx and libav, but it seems that libvpx is a shared library and it has to be actually hooked up to a decoder, or possibly that libvpx is an encoding libraray only. Libav 10 was released on 23rd March 2014 and has added a VP9 decoder - see http://git.libav.org/?p=libav.git;a=blob;f=Changelog;hb=refs/tags/v10
Libav 10 is available for download from https://libav.org/download.html#release_10 ** Tags added: trusty -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1296378 Title: Activate VP9 codec in libav To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libav/+bug/1296378/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
