Centos 安装 ffmpeg

1.安装EPEL Release,因为安装需要使用其他的repo源,所以需要EPEL支持:

yum install -y epel-release

2.如果出现缺少Code提示,可以：

sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7

3.安装完成之后,可以查看是否安装成功

yum repolist

4.安装Nux-Dextop源

#导入一个Code
sudo rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro
#安装nux-dextop 源
sudo rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-1.el7.nux.noarch.rpm

5.查看repo源是否安装成功

yum repolist

6.yum安装ffmpeg:

yum install -y ffmpeg

7.安装完成后检查ffmpeg 版本:

ffmpeg -version

ThinkPHP 5.1 安装php-ffmpeg

1.进入TP5.1Execute in the project directory directory

composer require php-ffmpeg/php-ffmpeg

2.控制器中引入

<?php
namespace app\index\controller;
use FFMpeg;

class Index
{
    
    public function index()
    {
    
		$configuration = array(
			// windows调用插件
			'ffmpeg.binaries' => env('root_path').'ffmpeg/bin/ffmpeg.exe',
			'ffprobe.binaries' => env('root_path').'ffmpeg/bin/ffprobe.exe', //This is where it is installed on the computer or server
			// linuxHow to call the plugin to report an error,在项目根目录下创建ffmpeg目录,Then create a hard link file in the directoryffmpeg
			//'ffmpeg.binaries' => '/usr/bin/ffmpeg.exe',
			//'ffprobe.binaries' => 'usr/bin/ffprobe.exe', 
			//'ffmpeg.binaries' => env('root_path').'ffmpeg/ffmpeg',
			//'ffprobe.binaries' => env('root_path').'ffmpeg/ffprobe', 
	        //'timeout' => 3600, // The timeout for the underlying process
	        //'ffmpeg.threads' => 12, // The number of threads that FFMpeg should use
		);

		$ffmpeg = FFMpeg\FFMpeg::create($configuration);
		// New file after synthesis 
		$outfile_path = env('root_path')."public/audio/new_file.wav";
		// audio source file
		$audio_path = env('root_path')."audio/";		
		$audio = $ffmpeg->open($audio_path.'0.wav');
		
		// List of audio files to be synthesized
		$file_arr[] = $audio_path.'0.wav';
		$file_arr[] = $audio_path.'1.wav';
		$file_arr[] = $audio_path.'2.wav';
		
		// The new file after synthesis exists,则先删除掉,重新合成
		if(file_exists($outfile_path)){
    
			unlink($outfile_path);
		}
		// Perform synthesis of audio files
		$audio->concat($file_arr)->saveFromSameCodecs($outfile_path, TRUE);			
		return true;
    }  
}
