This is an issue of paraview. Paraview is written in C++ while
libavutil is written in C. The ISO C99 standard (7.18.4) specifies
that C++ implementations should define UINT64_C only when
__STDC_CONSTANT_MACROS is defined, so even when stdint.h is included,
UINT64_C may be not in scope in C++ programs, but this never happens
in C programs.
