msys如何编译64位ffmpeg 带x264 x265

前面的文章讲述了编译32位ffmpeg 以及相关内容的过程。

现在讲述如何编译64位ffmpeg的过程。

编译环境搭建可以参考前面的文章。

注意在msys2中的编译器可以使用自带的gcc，也可以使用qt mingw中的gcc，可以通过修改PATH的先后顺序来决定使用哪一个编译器。

1、编译64位X264

./configure --prefix=$(pwd)/install --host=x86_64-w64-mingw32 --enable-shared --enable-static
make -j8
make install
cd install/bin
file x264.exe

2、编译x265

使用cmake生成mingw makefiles文件，主要在系统环境变量中设置qt的相关路径。

3、编译64位qsv

autoreconf -i
./configure --prefix=$(pwd)/install --host=x86_64-w64-mingw32 --enable-shared --enable-static
make -j8
make install

4、编译64位 ffmpeg

export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/cygdrive/e/softdev/transit/QtPro/x264-master-x64/x264-master/install/lib/pkgconfig/:/cygdrive/e/softdev/transit/QtPro/x265-master-x64/x265-master/build/mingw64/install/lib/pkgconfig/:/cygdrive/e/softdev/transit/QtPro/mfx_dispatch-master-x64/mfx_dispatch-master/install/lib/pkgconfig/

make -j8
make install
