CentOS 7 - Updates for x86_64: system environment/libraries: libtheora
libtheora - Theora Video Compression Codec
Theora is Xiph.Org's first publicly released video codec, intended
for use within the Ogg's project's Ogg multimedia streaming system.
Theora is derived directly from On2's VP3 codec; Currently the two are
nearly identical, varying only in encapsulating decoder tables in the
bitstream headers, but Theora will make use of this extra freedom
in the future to improve over what is possible with VP3.
