它似乎通过websocket流视频是一个可行的选择，就像在流帧和绘制他们在画布之类的东西。

使用JavaScript在websockets上传输视频流

我认为这将提供另一个级别的保护，使客户更难获取视频，当然解决了您的问题，“另存视频为…”右键单击上下文菜单选项(过量?!)．

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.

我们最终使用了url过期的AWS CloudFront。视频将加载，但当用户右键单击并选择另存为最初收到的视频url时，该视频已过期。搜索CloudFront Origin Access Identity。

生成视频url需要一个密钥对，这个密钥对可以在AWS CLI中创建。供参考，这不是我的代码，但它工作得很好!

$resource = 'http://cdn.yourwebsite.com/videos/yourvideourl.mp4';
$timeout = 4;

//This comes from key pair you generated for cloudfront
$keyPairId = "AKAJSDHFKASWERASDF";

$expires = time() + $timeout; //Time out in seconds
$json = '{"Statement":[{"Resource":"'.$resource.'","Condition" {"DateLessThan":{"AWS:EpochTime":'.$expires.'}}}]}';     

//Read Cloudfront Private Key Pair
$fp=fopen("/absolute/path/to/your/cloudfront_privatekey.pem","r"); 
$priv_key=fread($fp,8192); 
fclose($fp); 

//Create the private key
$key = openssl_get_privatekey($priv_key);
if(!$key)
{
    echo "<p>Failed to load private key!</p>";
    return;
}

//Sign the policy with the private key
if(!openssl_sign($json, $signed_policy, $key, OPENSSL_ALGO_SHA1))
{
    echo '<p>Failed to sign policy: '.openssl_error_string().'</p>';
    return;
}

//Create url safe signed policy
$base64_signed_policy = base64_encode($signed_policy);
$signature = str_replace(array('+','=','/'), array('-','_','~'), $base64_signed_policy);

//Construct the URL
$url = $resource.'?Expires='.$expires.'&Signature='.$signature.'&Key-Pair-Id='.$keyPairId;

return '<div class="videowrapper" ><video autoplay controls style="width:100%!important;height:auto!important;"><source src="'.$url.'" type="video/mp4">Your browser does not support the video tag.</video></div>';

如果你正在寻找一个完整的解决方案/插件，我发现这个非常有用 https://github.com/mediaelement/mediaelement

作为客户端开发人员，我推荐使用blob URL， blob URL是一个引用二进制对象的客户端URL

<video id="id" width="320" height="240"  type='video/mp4' controls  > </video>

在HTML中，让你的视频src为空， 在JS中使用AJAX获取视频文件，确保响应类型是blob

window.onload = function() {
    var xhr = new XMLHttpRequest();
    xhr.open('GET', 'mov_bbb.mp4', true);
    xhr.responseType = 'blob'; //important
    xhr.onload = function(e) {
        if (this.status == 200) {
            console.log("loaded");
            var blob = this.response;
            var video = document.getElementById('id');
            video.oncanplaythrough = function() {
                console.log("Can play through video without stopping");
                URL.revokeObjectURL(this.src);
            };
            video.src = URL.createObjectURL(blob);
            video.load();
        }
    };
    xhr.send();
}

注意:大文件不建议使用此方法

EDIT

使用跨源阻塞和头标记检查来防止直接下载。 如果视频是通过API传递的;使用不同的http方法(PUT / POST)来代替'GET'

以下是我所做的:

function noRightClick() { alert("You cannot save this video for copyright reasons. Sorry about that."); } <body oncontextmenu="noRightClick();"> <video> <source src="http://calumchilds.com/videos/big_buck_bunny.mp4" type="video/mp4"> </video> </body> This also works for images, text and pretty much anything. However, you can still access the "Inspect" and the "View source" tool through keyboard shortcuts. (As the answer at the top says, you can't stop it entirely.) But you can try to put barriers up to stop them.
