禁止视频下载 [英] Prevent Video downloading

问题描述

我想知道如何防止他人下载我网站中的视频. 我的网站可以选择上传视频(flv或mp4格式.管理员会上传它们)，并且用户只要支付一定的费用，就可以在线观看课程视频(使用flowplayer).

i want to know how can we prevent others to download the videos in my site. My site has the option of video uploading (in flv or mp4 format. Admin will upload them) and users can view the course videos online (using flowplayer) once they pay some amount.

但是我观察到的是，用户可以使用Freecorder之类的工具下载这些视频. 我不希望发生这种情况，因为视频具有限制性的访问权限，并且仅在特定的时间段内(直到用户的成员资格到期).

But what i observed is that the users can download those videos using tools like Freecorder. I dont want this to happen, because videos have restrictive access and only for a particular period of time (till the user's membership expires).

那么，如何防止用户下载我网站中的视频?

So how can i prevent the user from being able to download the videos in my site ?

推荐答案

视频分发的基本规律与

The fundamental law of video distribution is very similar to the fundamental law of software licensing. It goes something like this: Once you put your video on a screen you don't control, you don't have control over distribution of your video any more.

即使您可以阻止他们下载文件，也无法阻止他们将VCR挂接到他们的视频卡并重新录制.即使您使用某种保护路径技术来阻止这种情况，也无法阻止他们将便携式摄像机对准屏幕.

Even if you could stop them from downloading the file, you can't stop them from hooking a VCR to their video card and re-recording it. Even if you use some protected-path technology to stop that, you can't stop them from pointing a camcorder at the screen.

如果要将视频保密，则需要在自己控制的屏幕上在剧院中放映视频，并请其他人观看观众观看视频录制设备.对再分配的影响只有一点点放慢了.

If you want to keep your videos under wraps, you need to show them in a theater under your control on screens you control, and have someone watching the audience for video recording equipment. Nothing else is going to have more than a very slight slowing effect on re-distribution.
