HOWTO insert video keying on the fly in streaming videos

[pofpof98]

Hi
I would to insert (on the fly) viewer information inside the streaming video as video keying.
At this time the only way to have this feature is to duplicate the video source for all the subscribed viewers before it is delivered which can cause heavy server activity and big disk space.
I am looking for a streaming server solution that could do the job on the fly by simply mixing the original video source with the viewer profile as video keying (like "This video is dedicated to M.Smith")
Can anyone help ?

The solution requires either lots of server resources. As an alternative you can create client software that does this for you, but less users will be able to use this software.

Why do you need this? Is it a way to protect videos from being recorded?

Do you want the key to be displayed on a user's screen or do you want to embed it into video files?

We would sell per viewer licenses so I want to insert a permanent video keying like "This video is licensed to M.Smith" and a few video markers (pretty much invisible) so in case of upload on dwnld web sites that i track the guy who did not respect the license terms and act over him

You can probably insert some information to video files similar to ID3 tags used in MP3 files. The problem is that screen video capture software allows to record any video from screen, so you won't be able to track these videos.

I don't really know whether any of the streaming servers supports this functionality, but you can always outsource your project via a freelance marketplace.
