問(wèn)題描述

我想知道我們?nèi)绾畏乐蛊渌讼螺d我網(wǎng)站中的視頻.我的網(wǎng)站可以選擇上傳視頻(flv 或 mp4 格式.管理員將上傳)，用戶支付一定金額后即可在線(使用 flowplayer)觀看課程視頻.

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.

但我觀察到的是，用戶可以使用 Freecorder 等工具下載這些視頻.我不希望這種情況發(fā)生，因?yàn)橐曨l的訪問(wèn)權(quán)限受到限制，并且只能在特定時(shí)間段內(nèi)使用(直到用戶的會(huì)員資格到期).

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).

那么如何防止用戶下載我網(wǎng)站中的視頻?

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

推薦答案

視頻分發(fā)的基本規(guī)律與 軟件許可的基本法.它是這樣的:一旦您將視頻放在不受您控制的屏幕上，您就無(wú)法再控制視頻的分發(fā).

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.

即使您可以阻止他們下載文件，也無(wú)法阻止他們將 VCR 連接到視頻卡并重新錄制.即使您使用一些受保護(hù)的路徑技術(shù)來(lái)阻止它，您也無(wú)法阻止他們將攝像機(jī)指向屏幕.

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.

如果您想保密您的視頻，您需要在您控制的影院中在您控制的屏幕上展示它們，并讓有人觀看觀眾以使用視頻錄制設(shè)備.除了對(duì)重新分配的非常輕微的減緩影響之外，沒有其他任何事情會(huì)產(chǎn)生更大的影響.

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.
