From Magnus Kessler, "FFmpeg headers need __STDC_CONSTANT_MACROS defined before stdint.h is loaded.

The file FFmpegHeaders.hpp sets this definition. However, if stdint.h is
already included through other files, it won't take any effect.

Include FFmpeg headers as early as possible in order to avoid stdint.h being
included on other paths.
