[FFmpeg-devel] [PATCH] Make implicit void pointer cast explicit

[Amir Mazzarella]

Thank you for your response! A C++ compiler can't do implicit casts like a
C compiler can, in this instance. This is fine for most of FFmpeg's
codebase, since these tricks are in C source files, but in this instance it
is in a header file. If any C++ code includes this header file, even with
extern "C", it won't be able to be compiled.
