Ubuntu下mingw和aarch64交叉编译x264/x265/openssl/freetype2的ffmpeg
0、前记
在浏览gpac的github时发现编译gpac库教程，十分的强大，我之前常用的库都有编译脚本，照着做就行，中间会出现一些错误，我也记录了下，主要是版本更新和git clone timeout，稍作修改即可通过。github原地址：https://github.com/gpac/gpac我fork和修改后的地址：https://github.com/lishi0105-1/gpac/wiki/GPAC-Build-Guide-for-MSYS-MinGW
1、ffmpeg下载
前往ffmpeg官网下载地址下载需要的最新ffmpeg发布版本
2、ffmpeg编译选项说明
在ffmpeg官网中有对ffmpeg编译选项的部分说明内容如下：
--enable-libfreetype：启用Freetype支持。
--enable-gpl：允许使用 GPL 代码并允许支持后处理、swscale 和许多其他功能。
--enable-version3：允许使用 (L)GPL 版本 3 代码。
--enable-nonfree: 允许使用非自由代码。请注意，生成的库和二进制文件将不可再分发。
--disable-static：此开关可防止安装库的静态版本。
--enable-shared：启用构建共享库，否则仅构建和安装静态库。
--disable-debug：禁止将调试符号构建到程序和库中。
--enable-libass: 通过 启用 ASS/SSA 字幕格式渲染libass。
--enable-libdrm：如果安装了libdrm-2.4.114 ，请使用此开关 来构建 “ kmsgrab ”输入模块，该模块对屏幕捕获或流式传输很有用。
--enable-libfdk-aac: 通过 启用 AAC 音频编码libfdk-aac。
--enable-libmp3lame: 通过 启用 MP3 音频编码libmp3lame。
--enable-libvorbis --enable-libtheoralibvorbis: 通过和启用 Theora 视频编码 libtheora。
--enable-libvorbis --enable-libvpxlibvorbis: 通过和启用 WebM 编码libvpx。
--enable-libx264: 通过 启用高质量的 H.264/MPEG-4 AVC 编码libx264。
--enable-libx265：通过 启用高质量 H.265/HEVC 编码libx265。
--enable-openssl：为网络流启用 HTTPS 协议。
--enable-gnutls--enable-openssl：如果要使用 GnuTLS而不是OpenSSL用于 HTTPS 协议 ，请使用此选项而不是。
--disable-doc: 禁用构建 html 文档。这仅在安装了Doxygen-1.9.6 并且您不想构建 html 文档 时才需要。
--enable-libpulse：为音频输出 启用 Pulseaudio支持。
gcc tools/qt-faststart.c -o tools/qt-faststart：这构建了qt-faststart程序，它可以修改 QuickTime 格式的电影（.mov或.mp4），以便标题信息位于文件的开头而不是结尾。这允许电影文件在整个文件下载完成之前开始播放。
完整的编译选项需查看**./configure --help**，具体编译选项的选择看个人需要，我们在嵌入式平台下一般编解码使用嵌入式硬件，所以不需要附带libx264、libx265选项；对于需要其他编译选项的请参照ffmpeg在linux下编译这篇文章，需要编译安装第三方库。
编译完成之后安装内容说明如下：
#安装的程序：
#ffmpeg、ffplay、ffprobe 和 qt-faststart
#安装的库：
#libavcodec.so、libavdevice.so、libavfilter.so、libavformat.so、libavutil.so、libpostproc.so、libswresample.so 和 libswscale.so
#安装目录：
#/usr/include/libav{codec,device,filter,format,util}, /usr/include/libpostproc, /usr/include/libsw{resample,scale}, #/usr/share/doc/ffmpeg-5.1.2,和/usr/share/ffmpeg
#简短说明
#ffmpeg 是一个命令行工具，用于将视频文件、网络流和来自电视卡的输入转换为多种视频格式
#ffplay 是一个使用ffmpeg库和 SDL库的非常简单和便携的媒体播放器
#ffprobe 从多媒体流中收集信息并以人类和机器可读的方式打印出来
#qt-faststart 将索引文件移动到 quicktime (mov/mp4) 视频的前面
#libavcodec.so 包含FFmpeg编解码器（编码和解码） 的库
#libavdevice.so FFmpeg设备处理库
#libavfilter.so 过滤器库，可以在解码器和编码器（或输出）之间改变视频或音频
#libavformat.so 包含ffplay 使用的文件格式处理（多种格式的 mux 和 demux 代码）以及允许生成音频或视频流的 库
#libavresample.so 包含音频和视频重采样函数的库。
#libavutil.so FFmpeg实用程序库
#libpostproc.so FFmpeg后处理库
#libswresample.so FFmpeg音频缩放库，它包含转换音频采样格式的函数
#libswscale.so FFmpeg图像缩放库
3、ffmpeg编译和安装
在源码目录下创建install文件夹作为安装目录，我的交叉编译配置如下：
./configure \
--prefix="$PWD/install" \
--enable-shared \
--enable-cross-compile \
--target-os=linux \
--arch=aarch64 \
--cc=aarch64-none-linux-gnu-gcc \
--cxx=aarch64-none-linux-gnu-g++ \
--strip=aarch64-none-linux-gnu-strip \
--enable-gpl \
--extra-libs=-ldl \
--extra-cflags="-fPIC" \
--extra-ldflags=-Wl,-Bsymbolic \
--extra-libs="-lpthread -lm"
配置完成后执行make -j8 & make install执行编译安装命令，在install下生成编译后的文件，这种配置生成的库非常大，于是做了裁剪，配置如下：
./configure \
--prefix=$(pwd)/install --arch=aarch64 --target-os=linux --enable-cross-compile --disable-asm --enable-gpl \
--cc=aarch64-none-linux-gnu-gcc \
--cxx=aarch64-none-linux-gnu-g++ \
--strip=aarch64-none-linux-gnu-strip \
--disable-gpl --enable-nonfree --enable-error-resilience \
--disable-debug --disable-shared --enable-small \
--disable-ffmpeg --disable-ffprobe --disable-ffplay --disable-programs --disable-symver\
--disable-doc --disable-htmlpages --disable-manpages --disable-podpages \
--disable-txtpages --enable-avformat --enable-avcodec --enable-swresample \
--disable-avresample --disable-avfilter --disable-avdevice --disable-postproc \
--disable-swscale --disable-everything --enable-decoder=h264 --enable-decoder=hevc \
--enable-decoder=pcm_alaw --enable-decoder=aac --enable-demuxer=aac --enable-demuxer=rtsp \
--enable-demuxer=pcm_alaw --enable-demuxer=h264 --enable-demuxer=hevc \
--enable-demuxer=m4v --enable-demuxer=avi --enable-demuxer=mov --enable-muxer=m4v --enable-muxer=rtsp \
--enable-muxer=h264 --enable-muxer=hevc --enable-muxer=pcm_alaw \
--enable-muxer=avi --enable-muxer=mov --enable-muxer=mp4 --enable-parser=h264 \
--enable-parser=aac --enable-parser=hevc --enable-protocol=file --disable-iconv \
--disable-v4l2-m2m --disable-indevs --disable-outdevs
裁剪后静态库不到4MB，也满足我的需要。
4、ubuntu22.04下编译MinGw版本的ffmpeg
众所周知qt使用的有MinGw编译器，msvc版本的ffmpeg库很多人编译过，如果想使用MingW版本ffmpeg库需要自行编译，将编译过程做下记录
4.1 安装编译依赖
sudo apt install -y cmake nasm mingw-w64 mingw-w64-tools
4.2 编译安装第三方库
4.2.1 编译安装x264
git clone https://code.videolan.org/videolan/x264.git
cd x264
./configure --cross-prefix=x86_64-w64-mingw32- --host=mingw64 --disable-swscale --disable-lavf --enable-pic --enable-static --prefix=$(pwd)/install
make -j8
make install
4.2.2 编译安装X265
git clone https://bitbucket.org/multicoreware/x265_git.git
mv x265_git x265
cd x265/build/
gedit build.cmake #在目录下新建一个build.cmake的文件
输入以下内容：
#!cmake
SET(CMAKE_SYSTEM_NAME Windows)
SET(cross_prefix x86_64-w64-mingw32-)
# specify the cross compiler
SET(CMAKE_C_COMPILER ${cross_prefix}gcc)
SET(CMAKE_CXX_COMPILER ${cross_prefix}g++)
SET(CMAKE_RC_COMPILER ${cross_prefix}windres)
SET(CMAKE_ASM_NASM_COMPILER nasm)
SET(CMAKE_CXX_FLAGS "-static-libgcc -static-libstdc++ -static -O3 -s")
SET(CMAKE_C_FLAGS "-static-libgcc -static-libstdc++ -static -O3 -s")
SET(CMAKE_SHARED_LIBRARY_LINK_C_FLAGS "-static-libgcc -static-libstdc++ -static -O3 -s")
SET(CMAKE_SHARED_LIBRARY_LINK_CXX_FLAGS "-static-libgcc -static-libstdc++ -static -O3 -s")
再创建一个生成编译中间文件夹
mkdir mingw
执行以下内容：
cmake -DCMAKE_TOOLCHAIN_FILE=../build.cmake -DCMAKE_INSTALL_PREFIX=$(pwd)/install -DENABLE_SHARED=0 -DENABLE_PIC=1 ../../source
执行脚本生成Makefile并编译安装
make -j8 && make install
4.2.3 编译zlib
前往zlib网站下载zlib-1.2.11.tar.gz，解压后进入目录，执行以下命令在同层目录下创建install并生成相关文件：
export CC=x86_64-w64-mingw32-gcc
./configure --prefix=$(pwd)/install --static
make -j8 && make install
export CC=""
4.2.4 编译libpng
前往libpng官网下载libpng-1.6.39.tar.gz，解压进入目录执行以下命令编译安装：
./configure --host=x86_64-w64-mingw32 --prefix=$PWD/install LIBS=-L/home/user/work/ffmpeg_mingw/x64/zlib-1.2.11/install/lib CPPFLAGS=-I/home/user/work/ffmpeg_mingw/x64/zlib-1.2.11/install/include --disable-shared
make -j8 && make install
4.2.5 编译freetype2
执行以下命令配置之前编译的libpng和zlib
export PKG_CONFIG_PATH=/home/user/work/ffmpeg_mingw/x64/libpng-1.6.39/install/lib/pkgconfig:/home/user/work/ffmpeg_mingw/x64/zlib-1.2.11/install/lib/pkgconfig
再执行以下命令配置生成Makefile
./configure --host=x86_64-w64-mingw32 CC=x86_64-w64-mingw32-gcc --prefix=$PWD/install
最终结果如下：
显示配置libpng和zlib成功；
执行编译和安装命令make -j8 && make install ;
4.2.6 编译openssl
前往openssl官网下载openssl-1.1.1s.tar.gz解压进入目录(openssl3版本在随后ffmpeg检查时不匹配会报错)，执行以下命令编译：
./Configure --prefix=$(pwd)/install no-asm mingw no-shared --cross-compile-prefix=i686-w64-mingw32- #32位编译
./Configure --prefix=$(pwd)/install no-asm mingw64 no-shared --cross-compile-prefix=x86_64-w64-mingw32- #64位编译
make -j8 && make install
4.3 编译ffmpeg
4.3.1 编译64位版本
解压下载的源码，进入源码路径，执行以下命令:
export PKG_CONFIG_PATH=""
export PKG_CONFIG_PATH=/home/user/work/ffmpeg_mingw/x64/libpng-1.6.39/install/lib/pkgconfig:$PKG_CONFIG_PATH
export PKG_CONFIG_PATH=/home/user/work/ffmpeg_mingw/x64/zlib-1.2.11/install/lib/pkgconfig:$PKG_CONFIG_PATH
export PKG_CONFIG_PATH=/home/user/work/ffmpeg_mingw/x64/openssl-3.0.7/install/lib64/pkgconfig:$PKG_CONFIG_PATH
export PKG_CONFIG_PATH=/home/user/work/ffmpeg_mingw/x64/freetype-2.12.0/install/lib/pkgconfig:$PKG_CONFIG_PATH
export PKG_CONFIG_PATH=/home/user/work/ffmpeg_mingw/x64/x265/build/mingw/install/lib/pkgconfig:$PKG_CONFIG_PATH
export PKG_CONFIG_PATH=/home/user/work/ffmpeg_mingw/x64/x264/install/lib/pkgconfig:$PKG_CONFIG_PATH
mkdir build
cd build
../configure \
--prefix=$(pwd)/install \
--arch=x86_64 \
--target-os=mingw32 \
--pkg-config-flags="--static" \
--cross-prefix=i686-w64-mingw32- \
--extra-libs=-lstdc++ \
--enable-shared \
--enable-static \
--enable-gpl \
--enable-nonfree \
--enable-version3 \
--enable-pic \
--enable-protocol=https \
--enable-openssl \
--enable-protocol=crypto \
--enable-libfreetype \
--enable-libx264 \
--enable-libx265 \
--disable-ffmpeg \
--disable-ffprobe
注意这里指定openssl库位置要指定lib64目录,32位编译指定lib目录
出现以下画面说明第三方x264，x265，freetype2，openssl链接成功。
出现以下输出则表示https协议使能成功：
如果不加--extra-libs=-lstdc++会出现ERROR: x265 not found using pkg-config错误，查看编译log发现类似于以下错误Undefined reference to operator new（错误没有截图，csdn上找到的类似图片)，这是因为libx265使用c++编译，ffmpeg采用c编译的问题；
如果不加--pkg-config-flags="--static"始终无法很好编译第三方库，不知道为啥。然后执行编译命令
make -j8 && make install
我的configure配置之后输出提示如下：

4.3.2 编译32位版本
步骤与64位版本基本相同，编译第三方库和ffmpeg时更改以下项即可：
--host=i686-w64-mingw32
--arch=x86_64
--target-os=mingw32
--cross-prefix=i686-w64-mingw32-
4.4 测试验证
在install目录下生成需要的库文件和bin文件，经测试可以在windows下用qtcreator的mingw-64位编译和使用；
我的qt编译环境如下:
qt的pro文件添加以下内容：
INCLUDEPATH += $$PWD/ffmpeg-4.4.3/include
LIBS += -L$$PWD/ffmpeg-4.4.3/lib/ \
-lavcodec \
-lavfilter \
-lavformat \
-lavutil \
-lswscale
库存放路径：
4.5 编译好的mingw版ffmpeg下载
包含32位静态和共享库，64位共享库。下载链接
5、gpac库编译
参考链接
git clone [email protected]:gpac/gpac.git
