description         WebM VP8/VP9 Codec SDK
long_description    The WebM VP8/VP9 codecs are being developed \
                    specifically to meet the demand for the consumption \
                    of video over the Internet, including professionally \
                    and amateur produced video-on-demand and conversational \
                    video content. VP9 is an evolution of the VP8 video \
                    codec and includes a number of enhancements and new \
                    coding tools that have been added to improve coding efficiency. \
                    The VP9 encoder in this release is not, as yet, feature complete.

# Build fix for MacPorts clang-3.5 and later:
#
# This is an intentional change to Clang. It now parses the assembly output by default even when emitting assembly so that the diagnostics are consistent between "clang -c" and "clang -S".
# The solution is either to pass -fno-integrated-as to the compiler, or change the assembly produced (& probably the script that processes it) so that it's valid. Note that commenting out the line won't work: comments get stripped by the same process.
# Current Xcode versions of clang > 602 corresponding to Xcode 6.3 or greater also need this fix
