我想要软件这使我能够执行以下操作：

I would like software that can enable me to do the following:

您（用户）在您的PC上的网络上。 您登录的网站上有几个视频文件（这些是位于服务器上的wmv文件）。 当您请求下载这些文件时，服务器会将您的用户信息插入到
现有视频文件的随机帧中。 我不想更改这些视频文件的长度，但希望定期向您尝试下载的文件中的现有视频帧插入几帧用户信息。 因此，软件
会在不更改原始版本的情况下呈现wmv文件，并将您的用户信息插入到您尝试下载的文件的精确副本中，并允许将该副本传输到您的PC。

You (User) are on the web at your PC.  You sign into a website which has several video files on it (these are wmv files sitting on a server).  When you request to download those files, the server inserts your user info onto some random frames of those existing video files.  I don't want to change the length of those video files, but want to insert a few frames of your user info at regular intervals onto existing video frames within the file you are trying to download.  So, the software takes rendered wmv files, without changing the original version, and inserts your user info onto an exact copy of the file you are trying to download and allows that copy to be transferred to your PC.

所以最终的结果就是这个。 假设您（用户）正在从特定网站下载视频文件，并且您的用户ID为"123"。 然后，一旦你请求一个视频文件，服务器就知道如何提取你的用户ID'123'并将这个id插入到
那些现有的视频帧，每次定期30秒，一次几帧，这样当你下载它，您下载的每个视频都会使用您唯一的用户ID（或MAC地址或IP）永久标记。 位于服务器
上的原始wmv文件没有标记任何用户ID信息，并且每次下载都不会更改。

So the end result would be this.  Let's say you (User) are downloading video files from a particular site and your user id is '123'.  Then, once you request a video file, the server knows how to extract your user id '123' and inserts that id onto those existing video frames at regular 30 second intervals for a few frames at a time so that when you download it, each video you download is marked permanently with your unique user id (or MAC address or IP).  The original wmv files sitting on the server do not have any user id info marked on them and are not altered with each download.

如果来自其他IP或MAC的其他用户请求相同的文件，他们会得到与你完全相同的视频，但他们会定期标记新的唯一IP / MAC，这样他们在播放时会看到与你完全相同的视频，除了他们
不看到你的用户信息，但看到他们自己的用户信息。

If another user from another IP or MAC requests the same files, they would get the exact same video as you, but instead their new unique IP/MAC would be marked at regular intervals so they see exactly the same video as you when they playback, except they don't see your user info, but instead see their own user info.

所以，我正在寻找一些软件放在我的服务器上，知道如何提取用户ID / MAC / IP信息和快速将该信息插入我服务器上的现有视频文件。 我希望这个软件能够一次又一次地快速完成。 
我希望每个新用户的每个新文件（视频）下载请求都能执行此软件，以便使用其唯一的MAC / IP /用户ID快速标记/标记每​​个视频，而无需更改正在下载的实际视频（以30秒的间隔标记那些随机的几帧
）。

So, I am looking for some software to put on my server that knows how to extract user id/MAC/IP info and quickly insert that info onto the existing video files on my server.  I want this software to be able to do this quickly over and over again.  I want each new file(video) download request from every new user to execute this software to rapidly mark/label each video with their unique MAC/IP/user id without changing the actual video being downloaded (except for marking those random few frames at 30 second intervals).

插入的用户信息可以是浅色字体，具有非常典型和超小尺寸和透明字体，定位到框架的角落，这不会干扰观看视频本身。 

The inserted user info could be in a light font, with very typical and extra small sized and transparent fonts, positioned to the corner of the frame, which would not interfere with viewing of the video itself. 

如果这对你有用，请告诉我。

Let me know if this makes sense to you.

推荐答案

您可以使用编码器在视频帧上添加叠加并在下载前进行编码，但这是一个相对昂贵的过程，因为您正在重新编码那些框架。或者（我不知道这是否适合您的情况）您可以从服务器流式传输
视频，并使用Silverlight客户端播放视频并使用某些Silverlight UI覆盖用户信息。

You could use Encoder to add an overlay on to the video frames and encode before downloading, however that is a relatively expensive process as you're re-encoding those frames. Alternatively (I don't know if this fits your scenario) you could just stream the video from your server and have a Silverlight client that plays back the video and overlays the user info using some Silverlight UI.
