交叉编译ffmpeg+x264+x265 (x86、arm-linux双版本)亲测有效
一站式脚本交叉编译ffmpeg
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

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

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

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

ERROR: x265 not found using pkg-config
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
