Changes applied: * Moved utility files to /util/. * Removed unused #includes. * Removed unused ::ffmpeg::tools function. * Removed unused variables. * Fixed missing parentheses in the version macro. * Fixed missing override on virtual function overrides and removed unnecessary virtual keyword from them. * Disabled additional warning for ATL headers on MSVC only. * Replaced direct printf parameters with their macro equivalent. * Replaced C-style casts with C++-style casts. * Applied clang-format again after an earlier change to the CMake file broke the integration for it.
