阻止HTML5视频下载(右键保存)?

如何从浏览器的右键菜单中禁用“另存为…”以防止客户端下载视频?

是否有更完整的解决方案来阻止客户端直接访问文件路径?

当前回答

你可以使用

<video src="..." ... controlsList="nodownload">

https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement/controlsList

它不会阻止保存视频，但它会删除上下文菜单中的下载按钮和“另存为”选项。

其他回答

controlsList在不添加任何其他JavaScript函数的情况下阻止下载开始全屏等操作

   <video width="400"  controlsList="nofullscreen nodownload"  controls>

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.

你不能。

例如，人们可以使用一些api例如desktopCapture, getUserMedia 允许用户记录屏幕、窗口、选项卡。

人们可以使用它并将其写入画布，然后将所有的块连接在一起以获得视频，

所以如果他们真的想要视频，没有办法阻止他们下载。

首先，要意识到完全阻止视频下载是不可能的，你所能做的只是让下载变得更加困难。也就是说，你隐藏了视频的来源。

网络浏览器会在缓冲区中临时下载视频，所以如果可以阻止下载，你也就阻止了视频被观看。

您还应该知道，世界上只有不到1%的人口能够理解源代码，这使得它相当安全。这并不意味着你不应该把它隐藏在源代码中——你应该这样做。

您不应该禁用右键单击，甚至更不应该显示一条消息说“由于版权原因，您无法保存此视频。对此我很抱歉。”正如这个答案所暗示的。

这对用户来说是非常烦人和困惑的。除此之外;如果他们在浏览器上禁用JavaScript，他们将能够右键单击并保存。

下面是一个你可以使用的CSS技巧:

video {
    pointer-events: none;
}

CSS不能在浏览器中关闭，保护您的视频而不实际禁用右键单击。然而，一个问题是控件也不能启用，换句话说，它们必须设置为false。如果你打算添加自己的播放/暂停功能，或者使用一个有独立于视频标签的按钮的API，那么这是一个可行的选择。

控件也有一个下载按钮，所以使用它也不是一个好主意。

下面是一个JSFiddle的例子。

如果你打算使用JavaScript禁用右键，那么也要将视频源存储在JavaScript中。这样，如果用户禁用JavaScript(允许右击)，视频将无法加载(它也更好地隐藏了视频源)。

从TxRegex回答:

<video oncontextmenu="return false;" controls>
    <source type="video/mp4" id="video">
</video>

现在通过JavaScript添加视频:

document.getElementById("video").src = "https://www.w3schools.com/html/mov_bbb.mp4";
