php implements ffmpeg to process video

Recently, there is a project that needs to use ffmpeg to process video. Here I wrote a demo to facilitate us to implement video operations.

Simple example of use

Note here that if ffmpeg cannot be executed, the installation address of ffmpeg needs to be passed in when instantiating, for example, the installation address of ffmpeg under linux is /usr/local/ffmepg, then it needs to be passed in /usr/local/ffmpeg/bin/ffmpeg when instantiating

1: Add text to the video

$ffmpeg = new FfmpegVideo();
$ffmpeg ->titleWater(
    'XXX',//原视频
    'XXX',//处理后保存视频
    'XXX',//文字
    [
        'x' => 30,//水平距离
        'y' => 30,//垂直距离
        'fontsize' => 20,//文字大小
        'fontcolor' => 'red',//文字颜色
        'shadowy' => 2,//文字阴影
    ],
    200,//每秒移动步长
    2//文字出现时间(秒)
);

2: Mute the video

$ffmpeg = new FfmpegVideo();
$ffmpeg->audioMute(
    'XXX',//原视频
    'XXX',//处理后保存视频
);

3: Video cropping

$ffmpeg = new FfmpegVideo();
$ffmpeg->clipVideo(
    'XXX',//原视频
    'XXX',//处理后保存视频
    0,//裁剪开始时间
    10//裁剪时长
);

4: Video stitching

$ffmpeg = new FfmpegVideo();
$ffmpeg->concatVideo(
    ['XXX', 'XXX'],//需要拼接的视频
    'XXX',//处理后保存视频
);

5: Merge audio into video

$ffmpeg = new FfmpegVideo();
$ffmpeg->mergeVideoAudio(
    'XXX',//视频
    'XXX',//音频
    'XXX',//处理后保存视频
    0//音频插入视频延时时间(秒)
);

6: Obtain video information (length, width, duration)

$ffmpeg = new FfmpegVideo();
$ffmpeg->getAttributes(
    'XXX',//视频
);
