一、 Linux 下安装

• yasm 安装

    cd /opt/src/yasm
    wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz
    tar -jxvf  yasm-1.3.0.tar.gz
    cd yasm-1.3.0 
    ./configure  --prefix=/usr/local/yasm
    make
    make install
    
    #配置环境变量
    vim /etc/profile
    
    export YASM=/usr/local/yasm
    export PATH=${YASM}/bin:${PATH}
    
    source /etc/profile
    
    #查看版本 测试是否安装成功
    yasm --version

    tar -jxvf 文件名
    cd nasm-2.13
    ./configure --prefix=/usr/local/nasm
    make 
    make install
    
    #配置环境变量

   tar xvf *
   cd harfbuzz
   ./configure --prefix=/usr/local/harfbuzz
   make 
   make install

   wget url
   tar xvf fontconfig
   cd fontconfig
   ./configure --prefix=/usr/local/fontconfig
   make 
   make install
   

• PKG_CONFIG_PATH 配置

   vim /etc/profile
   
   export PKG_CONFIG_PATH=/usr/local/x264/lib/pkgconfig:/usr/local/freetype/lib/pkgconfig:/usr/local/harfbuzz/lib/pkgconfig:/usr/local/fribidi/lib/pkgconfig:/usr/local/libass/lib/pkgconfig
   export PATH=${PKG_CONFIG_PATH}/bin:${PATH}
   
   #生效
   source /etc/profile
  

• ld.so.conf 配置

   vim /etc/ld.so.conf
   
   #添加一下内容
   /usr/local/ffmpeg/lib
   /usr/local/x264/lib
   /usr/local/freetype/lib
   /usr/local/firbidi/lib
   /usr/local/harfbuzz/lib
   /usr/local/libass/lib
   
   #生效
   ldconfig
  

• ffmpeg 安装

   tar -jxvf ffmpeg-4.1
   cd ffmpeg
   ./configure --prefix=/usr/local/ffmpeg --enable-libx264 --enable-gpl --enable-libass --enable-fontconfig
   make 
   make install
  
   #配置环境变量
   export FFMPEG=/usr/local/ffmpeg
   export PATH=${FFMPEG}/bin:${PATH}
   
   source /etc/profile
   
   ffmpeg --version

• 配置

   安装好 x264
   vim /etc/ld.so.conf
   在该文件夹中添加
   /usr/local/ffmpeg/lib
   /usr/local/x264/lib
   
   #配置生效
   ldconfig

PHP 安装扩展包

• Laravel 安装 php-ffmpeg

    composer require php-ffmpeg/php-ffmpeg
    
    composer 阿里云镜像源报错则在 composer.json中加入
    
    "php-ffmpeg/php-ffmpeg": "^0.18.0"
    

代码示例

• 初始化对象

    $this->ffmpeg = FFMpeg::create(array(
            'ffmpeg.binaries'  => '/usr/local/ffmpeg/bin/ffmpeg',
            'ffprobe.binaries' => '/usr/local/ffmpeg/bin/ffprobe',
            'timeout'          => 3600, // The timeout for the underlying process
            'ffmpeg.threads'   => 12,   // The number of threads that FFMpeg should use
        ));

• 截取封面图

     $video = $this->ffmpeg->open($url_1);
     $frame = $video->frame(TimeCode::fromSeconds(2));
     $frame->save(public_path().'/upload/image.jpg');
    

• 视频裁剪

    $clip = $video->clip(TimeCode::fromSeconds(1),TimeCode::fromSeconds(15));
    $clip->save(new X264(), public_path().'/upload/video.mp4');

• 视频拼接

    $new_file_name = date('YmdHis').'.mp4';
    $newFile = public_path() . '/upload/'.$new_file_name.'';
    $video->concat(array($url_1,$url_2,$url_3))->saveFromSameCodecs($newFile,false);
    
    ps:
    如果视频地址为url，使用上述方法则会报错：Protocol 'http' not on whitelist 'file,crypto'!
    
    解决视频地址为url：
    
    $ffmpeg_exec = '/usr/local/ffmpeg/bin/ffmpeg -f concat -safe 0 -protocol_whitelist "file,http,https,rtp,udp,tcp,tls"   -i '.$filelist.' -c copy '.$newFile.'';
  
    exec($ffmpeg_exec,$output,$result);
    
    ps：
    $filelist.txt 文件内容格式为：
        file    'http://www.xxxx.com/x.mp4'
        file    'http://www.xxxx.com/x1.mp4'
        ...    
        
    
    若遇到exec() 返回值为 127时，则需要查看文件执行权限  
            

• 插入字幕

    $video = $this->ffmpeg->open($url_1);
    $new_file_name = date('YmdHis').'.mp4';
    $newFile = public_path() . '/upload/'.$new_file_name.'';
    $clip = $video->clip(TimeCode::fromSeconds(1),TimeCode::fromSeconds(15));
    $clip->save(new X264(), $newFile);
    $new_video_file = time().'_'.rand(100,999).'.mp4';
    $new_video_path = public_path().'/upload/' . $new_video_file;
    $video_srt_path = public_path().'/upload/test.srt';
    $ffmpeg_exec = '/usr/local/ffmpeg/bin/ffmpeg -i '.$newFile.' -vf subtitles='.$video_srt_path.' -y '.$new_video_path.' ';
    
    exec($ffmpeg_exec,$output,$code);
    if ($code == 0){
        echo 'success';
    }
