mac 下 qt 搭建 ffmpeg

Posted 2020-10-26

1.新建一个项目
在.pro 文件设置include和libs 注意他的 libs 有俩个路径是别搞错了。（不行可以各种试。）
网上说要加
LIBS += -liconv
QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.11这里没加也可以。
主要是这俩句
LIBS += -L/usr/local/Cellar/ffmpeg/3.4.2/lib -lavcodec -lavdevice -lavfilter -lavformat -lavutil -lpostproc -lswscale
INCLUDEPATH += "/usr/local/include" （也有俩这里加了一个也通过了#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

#LIBS+=/usr/local/Cellar/ffmpeg/3.4.2/lib
