使用Vimeo等服务:登录Vimeo > Goto Video >设置>隐私>标记为安全，也可以选择嵌入域。一旦设置了嵌入域，它将不允许任何人嵌入视频或从浏览器显示它，除非从指定的域连接。所以，如果你有一个页面在你的服务器上是安全的，它在iframe中加载Vimeo播放器，这使得它很难绕过。

这是一个简单的解决方案，为那些希望简单地从html5视频删除右键单击“保存”选项

$(document).ready(function(){
   $('#videoElementID').bind('contextmenu',function() { return false; });
});

你不能。

这是因为浏览器的设计目的就是:提供内容。但你可以让它更难下载。

方便的“解决方案”

我会把我的视频上传到第三方视频网站，比如YouTube或Vimeo。他们有很好的视频管理工具，优化设备的播放，他们努力防止他们的视频被撕掉，而你却没有付出任何努力。

解决方案1、禁用“右键单击”

你可以禁用上下文菜单事件，也就是“右键单击”。这将防止你的常规skiddie公然撕扯你的视频右击和另存为。但他们可以禁用JS，绕过这个问题，或者通过浏览器的调试器找到视频源。另外，这是糟糕的用户体验。在上下文菜单中有很多合法的东西，而不仅仅是另存为。

解决方案2，视频播放器库

使用自定义视频播放器库。它们中的大多数实现了视频播放器，可以根据您的喜好定制上下文菜单。你不会得到默认的浏览器上下文菜单。如果他们确实提供类似于另存为的菜单项，你可以禁用它。但同样，这是一个JS的解决方案。弱点类似于解决方案1。

解决方案3,HTTP直播

另一种方法是使用HTTP Live Streaming提供视频。它本质上是把视频切成块，然后一个接一个地播放。这就是大多数流媒体网站提供视频的方式。因此，即使你设法另存为，你只保存了一部分，而不是整个视频。收集所有的块并使用一些专用软件将它们缝合起来需要更多的努力。

解决方法4，在画布上作画

另一种技巧是在<canvas>上绘制<video>。在这种技术中，使用一些JavaScript，您在页面上看到的是一个<canvas>元素从隐藏的<video>渲染帧。因为它是一个<canvas>，上下文菜单将使用一个<img>的菜单，而不是一个<video>的。你会得到另存图像，而不是另存视频。

解决方案5,CSRF令牌

您还可以利用CSRF令牌。您可以让服务器在页面上发送一个令牌。然后使用该令牌获取视频。您的服务器在提供视频之前检查它是否是一个有效的令牌，或者获得HTTP 401。这个想法是，你只能通过有一个令牌来获得一个视频，你只能从页面来，而不是直接访问视频url。

+1简单和跨浏览器的方式: 你也可以用css z-index和不透明度把透明的图片放在视频上。 这样用户将在上下文菜单中看到“另存图片为”而不是“保存视频”。

简单回答:像youtube那样加密链接，不知道怎么做，不如问问youtube/谷歌他们是怎么做的。(以防你想直奔主题。)

I would like to point out to anyone that this is possible because youtube does it and if they can so can any other website and it isn't from the browser either because I tested it on a couple browsers such as microsoft edge and internet explorer and so there is a way to disable it and seen that people still say it...I tries looking for an answer because if youtube can than there has to be a way and the only way to see how they do it is if someone looked into the scripts of youtube which I am doing now. I also checked to see if it was a custom context menu as well and it isn't because the context menu is over flowing the inspect element and I mean like it is over it and I looked and it never creates a new class and also it is impossible to actually access inspect element with javascript so it can't be. You can tell when it double right-click a youtube video that it pops up the context menu for chrome. Besides...youtube wouldn't add that function in. I am doing research and looking through the source of youtube so I will be back if I find the answer...if anyone says you can't than, well they didn't do research like I have. The only way to download youtube videos is through a video download.

Okay...I did research and my research stays that you can disable it except there is no javascript to it...you have to be able to encrypt the links to the video for you to be able to disable it because I think any browser won't show it if it can't find it and when I opened a youtube video link it showed as this "blob:https://www.youtube.com/e5c4808e-297e-451f-80da-3e838caa1275" without quotes so it is encrypting it so it cannot be saved...you need to know php for that but like the answer you picked out of making it harder, youtube makes it the hardest of heavy encrypting it, you need to be an advance php programmer but if you don't know that than take the person you picked as best answer of making it hard to download it...but if you know php than heavy encrypt the video link so it only is able to be read on yours...I don't know how to explain how they do it but they did and there is a way. The way youtube Encrypts there videos is quite smart so if you want to know how to than just ask youtube/google of how they do it...hope this helps for you although you already picked a best answer. So encrypting the link is best in short terms.

你在浏览器中看到的一切都是下载的内容。这里提到的问题是如何在浏览器中保存这些内容。要查看内容，客户端浏览器从内容服务器下载并在本地提供。

一种流行的解决方案是将(短暂的)内容仅保存在浏览器中，并在有限的时间内，以一种不能直接保存的方式保存。blob是这种方法的一种实现，它具有减少带宽和存储开销的额外好处，因为内容存储在二进制对象中。

内容的短有效期使得普通用户几乎不可能持久存储，因为在用户尝试保存过期内容之前会显示新内容。
