PHP-FFmpeg

什么是FFmpeg

FFmpeg是一个自由软件，可以运行音频和视频多种格式的录影、转换、流功能，包含了libavcodec ─这是一个用于多个项目中音频和视频的解码器库，以及libavformat——一个音频与视频格式转换库。
这个项目最初是由Fabrice Bellard发起的，而现在是由Michael Niedermayer在进行维护。许多FFmpeg的开发者同时也是MPlayer项目的成员，FFmpeg在MPlayer项目中是被设计为服务器版本进行开发。

基本用法

实例对象

$ffmpeg = FFMpeg\FFMpeg::create(array(
    //ffmpeg指令文件的引用，按实际情况设置，引用失败会提示Unable to load FFMpeg
    'ffmpeg.binaries'  => '/usr/local/Cellar/ffmpeg/3.2.4/bin/ffmpeg',
    'ffprobe.binaries' => '/usr/local/Cellar/ffmpeg/3.2.4/bin/ffprobe',
    'timeout'          => 3600, // The timeout for the underlying process
    'ffmpeg.threads'   => 12,   // The number of threads that FFMpeg should use
));

视频转码

$video = $ffmpeg->open(public_path().'/upload/audio.mp4');

$format = new FFMpeg\Format\Video\X264('libmp3lame', 'libx264');
$format->on('progress', function ($video, $format, $percentage) {
    echo "$percentage % transcoded";
});

$format
    ->setKiloBitrate(1000)
    ->setAudioChannels(2)
    ->setAudioKiloBitrate(256);

$video->save($format, public_path().'/upload/video.mp4');
