抖音小视频去水印 PHP实战

我们都知道，抖音视频都有水印,我们要想无水印的视频，咋办?  目前市面上所有的去水印大多都是爬数据，然后分析,并不是直接拿到视频, 对视频做处理的。今天我们用PHP来实现 抖音去水印的功能.

  废话少说, 直接撸啊撸代码:

返回的数据拼接格式: 

{
    "success": true,
    "msg": "获取视频信息成功",
    "data": {
        "mp3": null,
        "nickname": "杭州美女榜",
        "desc": "听说这个小姐姐是个有5000w粉丝的大网红，有认识的吗？#街拍 #穿搭",
        "duration": "听说这个小姐姐是个有5000w粉丝的大网红，有认识的吗？#街拍 #穿搭",
        "videoUrl": "http://v6-dy.ixigua.com/42ba8f28dafc4dfd550af8b1d4bd8395/5ef58237/video/tos/cn/tos-cn-ve-15/2d4c19b7457443b2bb9c35660ffe9ac6/?a=1128&br=4974&bt=1658&cr=0&cs=0&dr=0&ds=6&er=&l=2020062612055201000806203713BFC627&lr=&mime_type=video_mp4&qs=0&rc=aml5ZWg0Zzg4cTMzZWkzM0ApZTk5OWZkOWVnNztnMzkzO2dxZF9sMHBxNF9fLS1iLS9zczZgLzMxYjYxLTM1LjItMTI6Yw%3D%3D&vl=&vr="
    }
}

 返回的URL: 

http://v6-dy.ixigua.com/42ba8f28dafc4dfd550af8b1d4bd8395/5ef58237/video/tos/cn/tos-cn-ve-15/2d4c19b7457443b2bb9c35660ffe9ac6/?a=1128&br=4974&bt=1658&cr=0&cs=0&dr=0&ds=6&er=&l=2020062612055201000806203713BFC627&lr=&mime_type=video_mp4&qs=0&rc=aml5ZWg0Zzg4cTMzZWkzM0ApZTk5OWZkOWVnNztnMzkzO2dxZF9sMHBxNF9fLS1iLS9zczZgLzMxYjYxLTM1LjItMTI6Yw%3D%3D&vl=&vr= 

 这就是无水印的。
