ffmpeg交叉编译arm
环境
- Ubuntu16.04 x86_64
- 交叉编译工具arm-linux-gnueabihf
- ARM平台 cortexa9
准备编译
以下均采用脚本进行编译，可自行根据 download_package () 中的下载地址下载包并存放在 compressed 目录中
我这里已经注释掉了 download_package
编译x86版本
在一个空目录下新建一个脚本 ，如 x86-make.sh ，写入以下内容
#!/bin/sh BASE=`pwd` OUTPUT_PATH=${BASE}/x86-install make_dirs () { #为了方便管理，创建有关的目录 cd ${BASE} && mkdir compressed x86-install source -p } tget () { #try wget filename=`basename $1` echo "Downloading [${filename}]..." if [ ! -f ${filename} ];then wget $1 fi echo "[OK] Downloaded [${filename}] " } #下载地址,可自行下载存放在 compressed 目录中 download_package () { cd ${BASE}/compressed tget https://code.videolan.org/videolan/x264/-/archive/master/x264-master.tar.bz2 tget https://ffmpeg.org/releases/ffmpeg-5.0.tar.gz tget http://download.videolan.org/videolan/x265/x265_3.2.tar.gz } tar_package () { cd ${BASE}/compressed ls * > /tmp/list.txt for TAR in `cat /tmp/list.txt` do tar -xf $TAR -C ../source done rm -rf /tmp/list.txt } make_yasm(){ cd ${BASE}/source/yasm* ./configure make -j8 && sudo make install } make_nasm(){ cd ${BASE}/source/nasm* ./configure make -j8 && sudo make install } make_x264() { cd ${BASE}/source/x264* ./configure --prefix=${OUTPUT_PATH}/ --enable-static --enable-pic make -j8 && make install } make_x265() { cd ${BASE}/source/x265*/build/linux # 编译安装 cmake -G "Unix Makefiles" \ -DCMAKE_INSTALL_PREFIX=${OUTPUT_PATH} \ -DCMAKE_ASM_NASM_FLAGS=-w-macro-params-legacy \ -DENABLE_SHARED:bool=off ../../source make -j8 && make install cd ${OUTPUT_PATH}/lib/pkgconfig # 修改x265.pc sed -i '9,9s/-lx265/-lx265 -lm -lstdc++ -ldl -lpthread/g' x265.pc sed -i '10,10s/-lstdc++/-lstdc++ -lm -lgcc_s -lgcc -lrt -ldl/g' x265.pc } make_sdl() { cd ${BASE}/source/SDL* # ./autogen.sh ./configure make -j8 && sudo make install } make_ffmpeg() { export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:${OUTPUT_PATH}/lib/pkgconfig/ cd ${BASE}/source/ffmpeg* ./configure \ --prefix=${OUTPUT_PATH}/ffmpeg5.0 \ --enable-gpl \ --enable-pthreads \ --enable-libx264 \ --enable-libx265 \ --enable-pic \ --enable-shared \ --enable-nonfree \ --enable-postproc \ --enable-ffplay make -j8 && make install } echo "Using ${BUILD_HOST}-gcc" make_dirs # download_package tar_package sudo apt install cmake -y sudo apt install pkg-config sudo apt-get install libx11-dev sudo apt-get install xorg-dev make_yasm make_nasm make_sdl make_x264 make_x265 make_ffmpeg

arm编译结果
目录如下
编译结果如下，all_without_ffmpeg 目录中包含 x264 x265
ffmpeg 目录中发现没有 ffplay ，可以用但是个人觉得还不够
添加ffplay
给脚本加亿点细节，核心就是交叉编译 SDL 库加上去即可
修改后的脚本如下

添加ffplay后的结果
如图，有了ffplay
file ffplay 一下，结果说明可以运行在arm板子上
上板测试
需要把 all_without_ffmpeg 和 ffmpeg5.0 目录中的 lib 中所有文件拷贝到开发板的 /usr/lib 下
把 ffmpeg5.0 目录中的 bin 中所有文件拷贝到开发板的 /usr/bin 下
插入SD卡到ubuntu，拷贝可使用命令
cd ffmpeg5.0
sudo cp -a bin/* /media/hammer/rootfs/usr/bin/
sudo cp -a lib/* /media/hammer/rootfs/usr/lib/
cd all_without_ffmpeg
sudo cp -a lib/* /media/hammer/rootfs/usr/lib/

开发板终端任意目录下输入以下命令
ffmpeg -f video4linux2 -s 640x480 -i /dev/video0 ./test.avi
# video4linux2 代表Linux下
# /dev/video0 代表摄像头设备
# ./test.avi代表输出路径

出现 test.avi 说明ffmpeg移植成功；同样，ffplay也可自行测试

编译x86遇到的问题
1. Error:libx264 not found.
ffbuild/config.log 报错提示

解决方案：
ffmpeg编译选项添加 --extra-libs="-lpthread -lm -ldl"
2. Error:x265 not found using pkg-config
ffbuild/config.log 报错提示

解决方案：
ffmpeg编译选项改 --pkg-config-flags="--static" 为 --pkg-config="pkg-config --static"
3. x264 using cpu capabilities: none!
使用 libx264 进行视频编码时，发现速度很慢，同时提示using cpu capabilities: none!
原因在于编译x264时加了编译选项 --disable-asm
解决方案：
下载nasm nasm下载地址
cd 目录
./configure
make -j8
sudo make install
# 查看安装是否成功
nasm --version

删去x264的编译选项 --disable-asm
