Chris Peterson 801d7c7d38 Bug 1388978 - Suppress some more clang warnings in media/ffvpx. r=rillian Since I am already poking around in ffvpxcommon.mozbuild's CFLAGS, also suppress these clang -Wvisibility and -Wstring-conversion warnings: media/ffvpx/libavutil/dummy_funcs.c:83:34 [-Wvisibility] declaration of 'struct AVBufferRef' will not be visible outside of this function media/ffvpx/libavutil/dummy_funcs.c:83:67 [-Wvisibility] declaration of 'struct AVFrame' will not be visible outside of this function media/ffvpx/libavutil/utils.c:119:26 [-Wstring-conversion] implicit conversion turns string literal into bool: 'char [19]' to '_Bool' And remove -Wno-logical-op-parentheses because clang does not currently report any -Wlogical-op-parentheses warnings for ffvpx.
