视频格式的长度属于视频的属性,一般包含在视频封装格式的头部标签中,并且不同的视频封装格式头部标签格式也不相同。
URL只是提供资源的定位,不会提供资源的内部属性。
除非这个URL中包含了视频播放长度信息,否则你将无从获取。
每个格式的视频文件都有视频长度的信息,吧视频文件下载到本地,然后解析二进制文件。

一般来说直接通过URL是无法拿到视频的相关信息的,你要么根据视频网站的API根据视频的ID获取视频的相关信息,要么就把视频直接下载下来利用PHP-FFMpeg(https://github.com/PHP-FFMpeg/PHP-FFMpeg#ffprobe)获取到视频的时间,为了避免以后重复下载,可以把相关信息存储下来,碰到下载过的就直接读取不用下载获取了。
