在包含标题位置的HTML视频标记中使用php文件到视频文件

Question

I came up with some weird stuff that I haven't seen before.

I used <source type="video/webm" src="test.php">

instead of <source type="video/webm" src="example.webm">

...Test.php file containing only this line of code:

header("Location: https://www.example.com/example.webm");

and it works..

Is this normal or maybe has some downside for the video/loading/flash(or browser support), is there actually any difference using test.php or example.webm directly? I am so confused because what I know... this is too good to be true, and too simple. Would appreciate any comment/pointer...

Answer 1

It is ok to use. The browser just looks for "https://www.example.com/example.webm" when accessing test.php, so the difference in load is very small. (as small as it takes your browser to be redirected).
