Hi all,

I have a bunch of flash videos that I need to watermark with user related information, to make illegal re-distribution of these files harder.

I'm wondering how can this be done server-side. If done client-side, it will be quite easy for the user to intercept the videos before they are watermarked.

Since the watermark should contain user-specific information I can't really watermark the videos before encoding them (unless I have an encoded video per user - not feasible).

I'm expecting this to affect the streaming performances a lot, though.

Any idea how this can be done (possibly in an efficient way)?

I've been looking for a solution to this for years, but nothing is conclusively documented. There are many Shoutcast Flash players out there (e.g. radio.de) so I know it's possible. However, most of my research leads to this: s = new Sound(); s.loadSound ("url.of.shoutcaststream:8003",true); Which… >>> More

Create NSC-File for multicast streaming with Windows Media Streaming

For streaming multicast I need to create a NSC-file for the players - this file is pseudo-coded by Microsoft. Now I need to create this file for each proxy-publishingpoint. Is there any way to stream multicast without the NSC-file or can I create the NSC-file on another way? Thanks for any idea ;) >>> More
