你会如何在网上展示视频？-HowwouldyoudisplayVideoontheweb?

Mostly video streaming sites like Hulu achieve a kind of poor-man's security by using RTMP to transfer the video data. You would need special server software to serve video via RTMP, for example Adobe Flash Media Server or WebORB.

大多数像Hulu这样的视频流媒体网站通过使用RTMP传输视频数据来实现一种穷人的安全性。您需要特殊的服务器软件才能通过RTMP提供视频,例如Adobe Flash Media Server或WebORB。

RTMP is a proprietary protocol, so this is a case of security through obscurity; it's non-trivial to download a copy of the video (you can't just grab the file from a URL), but there are programs out there that are capable intercepting the stream and keeping a copy.

RTMP是一种专有协议,所以这是一个通过默默无闻的安全案例;下载视频副本并不是一件容易的事情(你不能只是从URL中获取文件),但有些程序能够拦截流并保留副本。

"For example, what makes my video content secure? " Nothing.

“例如,是什么让我的视频内容安全?”没什么。

"Is it the player on the client?" Neither. Anyone can write a client and retain the video content. Remember this. Anyone can write a client. This client can absorb and save your video. Nothing can stop this. Nothing.

“它是客户的玩家吗?”都不是。任何人都可以编写客户端并保留视频内容。记住这一点。任何人都可以写客户。此客户端可以吸收和保存您的视频。什么都不能阻止这一点。没有。

"is it the server that hosts the content?" No. Server is only one piece of security. You have to secure the protocol. And the client. And anyone can write a client and retain the video content.

“它是托管内容的服务器吗?”不。服务器只是一个安全措施。你必须保护协议。和客户。任何人都可以编写客户端并保留视频内容。

"is it the streaming process?" No. Protocol is only one piece of security. You have to secure the server, the protocol and the client. And anyone can write a client and retain the video content.

“这是流媒体流程吗?”协议只是一个安全措施。您必须保护服务器,协议和客户端。任何人都可以编写客户端并保留视频内容。

"who hosts the streaming servers and what difference does this make?" You host the streaming video servers. Otherwise, you might as well use YouTube.

“谁拥有流媒体服务器,这有什么不同?”您托管流式视频服务器。否则,您也可以使用YouTube。

Edit

"The problem is I don't understand how everything fits together."

“问题是我不明白一切如何融合在一起。”

"For example, what makes my video content secure?"

“例如,是什么让我的视频内容安全?”

These are unrelated. You keep mentioning security, AND not knowing how "everything" fits together.

这些是无关的。你一直提到安全性,而不知道“一切”如何融合在一起。

Here's a suggestion: stop mentioning security -- edit your question to eliminate all references to security and see if you get more useful answers.

这里有一个建议:停止提及安全性 - 编辑你的问题以消除所有对安全性的引用,看看你是否得到了更多有用的答案。

Many companies sell streaming media servers. You put HTML in your page that references the streaming media site.

许多公司销售流媒体服务器。您将HTML放在引用流媒体网站的页面中。

Example. Apple sells Quicktime media server. Read http://developer.apple.com/documentation/QuickTime/Conceptual/QTScripting_HTML/QTScripting_HTML_Document/chapter_1000_section_1.html for lots of information on how to present video from quicktime.

例。 Apple销售Quicktime媒体服务器。请阅读http://developer.apple.com/documentation/QuickTime/Conceptual/QTScripting_HTML/QTScripting_HTML_Document/chapter_1000_section_1.html,了解有关如何通过q​​uicktime呈现视频的大量信息。

Before you go too far worrying about setting up these secure streaming protocol client server whatevers, make sure you weigh up the cost of your time getting this going, versus the cost of someone downloading your video.

在您过度担心设置这些安全的流媒体协议客户端服务器时,请确保权衡您的时间成本与下载视频的人的成本。

Just to be clear: if your server is sending to a client, then they can copy (download) it. There's no way around it.

需要明确的是:如果您的服务器正在发送给客户端,那么他们可以复制(下载)它。没有办法绕过它。

What I'd probably try doing if you wanted to try to avoid users downloading the files is this (I'll assume you're using FLV files, since they're the de facto standard on the web these days):

如果你想试图避免用户下载文件,我可能会尝试这样做(我假设你正在使用FLV文件,因为它们现在是网上事实上的标准):

• Put the FLV files in a non web-accessible directory.

将FLV文件放在不可通过Web访问的目录中。

• Have a player.swf file request the file via a script on your site, eg: video.php?file=myVideo.flv

让player.swf文件通过您网站上的脚本请求文件,例如:video.php?file = myVideo.flv

• The video.php can then perform whatever security checks you'd like: for example, require logins, check the referrer, etc.

然后,video.php可以执行您想要的任何安全检查:例如,需要登录,检查引荐来源等。

• If the security checks are ok, then pass through the appropriate video file. If not, then perhaps have a short back-up video which is an ad for your site or something, saying "to watch this video, please come to mysite.com!"

如果安全检查没问题,则通过相应的视频文件。如果没有,那么可能会有一个简短的备用视频,这是一个适合您网站的广告或其他内容,并说“观看此视频,请访问mysite.com!”

2.I need to control what the player looks like

我需要控制玩家的样子

Download and customise a free player like OSFLV.

下载并自定义像OSFLV这样的免费播放器。

4.I need as much protection as possible in terms of protecting the content from being downloaded

4.在保护内容不被下载方面,我需要尽可能多的保护

Forget it.

DRM for FLV exists, but you'll have to pay Adobe a load of money for Flash Media Server and Flash Media Rights Management Server, you'll lose client compatibility and ease of deployment, and in the end it's still breakable. Big old waste of time.

FLV的DRM存在,但您必须向Adobe支付大量资金用于Flash Media Server和Flash Media Rights Management Server,您将失去客户端兼容性并易于部署,并且最终它仍然可以破解。大浪费时间。

Accept that some people will download your videos, and put a big watermark on them so at least when they do you're getting free advertising.

接受有些人会下载你的视频,并在他们身上留下一个大水印,这样至少当你获得免费广告时。
