MEDIA_EXPORT is missing, here and @42.

The export aren't needed (see the green build), since these are just PODs and
the entire definition is in the header.

This probably got lost in the thread, but it's problematic to mix
__attribute__(...) syntax with alignas(...). Since we don't actually need to
export these sybols, we can sidestep it by removing the EXPORT macros.

If this is needed at some point in the future, we'll probably switch the export
macros over to using C++11 attribute syntax, which will work with alignas.
