交叉编译ffmpeg+x264+x265 （x86、arm-linux双版本）亲测有效

企业开发 2023-04-10 07:00:51 阅读次数: 0

环境

  1. Ubuntu16.04 x86_64
  2. 交叉编译工具arm-linux-gnueabihf
  3. 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_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/

arm编译结果

目录如下

在这里插入图片描述

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

在这里插入图片描述

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

如图，有了ffplay
file ffplay 一下，结果说明可以运行在arm板子上

在这里插入图片描述

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

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
