使用PHP进行视频编辑

Question

是否可以使用PHP在上传的视频上录制语音？

Answer 1

不,你不能,至少不能只使用PHP,因为PHP本身并不提供录制声音和编辑视频所需的库.

要实际录制视频和声音,您需要用于视频编辑的ffmpeg(用于PHP的方便扩展)和用于服务器上安装的声音的SoX等库.然后,您可以使用exec()PHP中的函数访问这些程序.但实施并不那么简单.

Answer 2

你可以使用 MLT 库和我的课程。您可以从此链接下载它https://github.com/1fer/mlt

特征

• 剪切和合并视频
• 通过转场连接视频
• 10 个现成的带有选项的过渡
• 可定制的擦除过渡
• 添加背景音频
• 加水印
• 添加带有选项的文本叠加
• 添加动画文本
• 在后台运行渲染
• 获取渲染进度百分比

要在服务器上安装此 Melt 库，请使用以下命令： sudo apt install melt

查看文档如何使用它，例如，使用以下代码加入剪辑：

require __DIR__ . '/vendor/autoload.php';

$videoProcessing = new Andchir\VideoProcessing([
    'melt_path' => '/usr/bin/melt',
    'session_start' => true
]);

// Join clips

$videoProcessing
    ->setProfile('hdv_720_25p')
    ->addOption(['joinClips' => [
        $rootPath . '/uploads/tmp/Social.mp4',
        $rootPath . '/uploads/tmp/Dog.mp4',
        $rootPath . '/uploads/tmp/Swans.mp4'
    ]])
    ->setOutputVideoOptions($rootPath . '/uploads/tmp/out1.mp4');

// Black color and fade transition

$videoProcessing
    ->setProfile('hdv_720_25p')
    ->addOption(['inputSource' => [
        'colour:black', ['out' => 24],
        $rootPath . '/uploads/tmp/Dog.mp4'
    ]])
    ->addOption(['mix' => 25])
    ->addOption(['mixer' => 'luma'])
    ->addOption(['inputSource' => [
        'colour:black', ['out' => 24]
    ]])
    ->addOption(['mix' => 25])
    ->addOption(['mixer' => 'luma'])
    ->setOutputVideoOptions($rootPath . '/uploads/tmp/out2.mp4'); 

// Join clips with transition

$videoProcessing
    ->setProfile('hdv_720_25p')
    ->addOption(['inputSource' => [
        $rootPath . '/uploads/tmp/Swans.mp4',
        $rootPath . '/uploads/tmp/Dog.mp4'
    ]])
    ->addOption(['mix' => 25])
    ->addOption(['mixer' => 'luma'])
    ->setOutputVideoOptions($rootPath . '/uploads/tmp/out3.mp4'); 

// Cut clips and join with transition

$videoProcessing
    ->setProfile('hdv_720_25p')
    ->addOption(['inputSource' => [

    ->addReadyMadeTransition('shiftRightIn', 25, [
        'width' => 1280,
        'height' => 720
    ])
    ->setOutputVideoOptions($rootPath . '/uploads/tmp/out4.mp4');  

// Add background audio with delay

$videoProcessing
    ->setProfile('hdv_720_25p')

    ->addWatermark($rootPath . '/uploads/tmp/SampleLogo.png', false, [
        'distort' => 1
    ])
    ->addReadyMadeTransition('shiftLeftIn', 25)
    ->setOutputVideoOptions($rootPath . '/uploads/tmp/out8.mp4'); 

// Add text overlay

// Start rendering in background

$progressLogPath = $videoProcessing->render();  

// Rendering progress

$percent = $videoProcessing->getRenderingPercent();

你还可以制作一些像Instagram中的滤镜效果等等。在这里阅读更多信息： https ://www.mltframework.org/plugins/PluginsFilters/
