用PHP合并视频文件 [英] Merging Video Files with PHP

问题描述

我有两个mp4文件，我想将它们合并.

I have two mp4 files and i want to merge them.

$media1 = file_get_contents($_SERVER['DOCUMENT_ROOT'].'/dir/media1.mp4');
$media2 = file_get_contents($_SERVER['DOCUMENT_ROOT'].'/dir/media2.mp4');

file_put_contents($_SERVER['DOCUMENT_ROOT'].'/dir/combined.mp4', $media1.$media2);

media1.mp4:1兆字节，10秒

media1.mp4 : 1 Megabyte, 10 second

media2.mp4:2兆字节，20秒

media2.mp4 : 2 Megabyte, 20 second

combined.mp4:3兆字节，但10秒(只有media1.mp4)

combined.mp4 : 3 Megabyte but 10 second (There is only media1.mp4)

如何合并这两个文件?

推荐答案

我希望您可以将编码后的视频流与$media1.$media2组合在一起，但可悲的是，您不喜欢那样.

I wish you could combine encoded video stream with $media1.$media2 but sadly, you can't like that.

幸运的是，php附带了exec()函数，并与小型 ffmpeg 程序一起使用让你做到这一点.

Fortunately for you, php come with a exec() function, and using that with the little ffmpeg program let you do that.

所以您要做的是用ffmpeg做一个PHP exec()并在那里进行合并.

So what you have to do is to do a php exec() with ffmpeg and do the merge there.

祝你好运！
