QT MAC FFMPEG

1.新建一個項目
在.pro 文件設置include和libs 註意他的 libs 有倆個路徑是別搞錯了。（不行可以各種試。）
網上說要加
LIBS += -liconv
QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.11這裏沒加也可以。
主要是這倆句
LIBS += -L/usr/local/Cellar/ffmpeg/3.4.2/lib -lavcodec -lavdevice -lavfilter -lavformat -lavutil -lpostproc -lswscale
INCLUDEPATH += "/usr/local/include" （也有倆這裏加了一個也通過了#INCLUDEPATH+=/usr/local/Cellar/ffmpeg/3.4.2/include）

#INCLUDEPATH+=/usr/local/Cellar/ffmpeg/3.4.2/include
INCLUDEPATH += "/usr/local/include"
#QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.11

#LIBS += "/usr/local/Cellar/ffmpeg/3.4.2/lib/libavcodec.a" #        "/usr/local/Cellar/ffmpeg/3.4.2/lib/libavdevice.a" #        "/usr/local/Cellar/ffmpeg/3.4.2/lib/libavfilter.a" #        "/usr/local/Cellar/ffmpeg/3.4.2/lib/libavformat.a" #        "/usr/local/Cellar/ffmpeg/3.4.2/lib/libavutil.a" #        "/usr/local/Cellar/ffmpeg/3.4.2/lib/libpostproc.a" #        "/usr/local/Cellar/ffmpeg/3.4.2/lib/libswresample.a" #        "/usr/local/Cellar/ffmpeg/3.4.2/lib/libswscale.a"
#LIBS += -liconv
