拖进包含ffmpeg 的库所添加的处理的信息
要在 user head search head 添加头文件
$(PROJECT_DIR)/TWIPCSDK/FFmpeg/include 选择recursive
然后要添加这几个库 libiconv.tbd libz.tbd libbz2.1.0.tbd
这三个库文件 bitcode 要设置为NO

10 duplicate symbols for architecture arm64

build active architecture Only 设置成 NO
skip install YES
Otherlink flags -OBJC

duplicate symbol _OBJC_IVAR_$_FrameData._height in:
    /Users/mac/Library/Developer/Xcode/DerivedData/decodeH264-dobzspglslbnfugtcanmutpeicab/Build/Intermediates/decodeH264.build/Debug-iphoneos/decodeH264.build/Objects-normal/arm64/VideoSurfaceView.o
    /Users/mac/Library/Developer/Xcode/DerivedData/decodeH264-dobzspglslbnfugtcanmutpeicab/Build/Intermediates/decodeH264.build/Debug-iphoneos/decodeH264.build/Objects-normal/arm64/VideoShowView.o

这里是说VideoShowView 和VideoSurfaceView 这两个view 的高度重复定义了，变量名相同发现 VideoShowView 这个没用，直接删了就好

duplicate symbol _uniforms in:
    /Users/mac/Library/Developer/Xcode/DerivedData/decodeH264-dobzspglslbnfugtcanmutpeicab/Build/Intermediates/decodeH264.build/Debug-iphoneos/decodeH264.build/Objects-normal/arm64/AAPLEAGLLayer.o
