更长的答案，它取决于你的目的有以下两种方式。

Longer answer, it depend upon your purpose there are 2 possibilities.

如果你想prevent人嵌入你的视频在其网站（从而利用你的带宽），问题是类似的热链接的图像。这涉及到像，检查引用（不是所有的用户代理供应商之一，虽然）。另一种选择是使的URL视频用户专用，例如临时网址超时，嵌入在URL中的反CSRF令牌，检查此相匹配的cookie等。

If you want to prevent people embedding your videos in their site (thus using your bandwidth) the problem is similar to that of hot linking images. This involves things like, checking the referrer (not all user agents supply one though). Another option is to make the URL for the video user specific, e.g. temporary URL that times out, embed an anti-csrf token in the URL, check this matches a cookie, etc.
