I'm not sure if this is the right place to ask, but I thought some
people here might have some knowledge on the subject and could at least
tell me if it was possible.
I am a web publisher who does VOD music videos. Because of label
agreements, I can't let people download the videos, just stream them. I
know that by streaming to them, I can't stop them from getting the
video, but I need to make it inconvenient. We've traditionally used
Windows Media and Real, which are true streaming and make it hard to save.
The wave of the future is flash though. We're rolling it out, but
unfortunately, Red5 is not quite ready for what we need. We push about
500 simultaneous 700k video streams at any given time, and red5 can't
quite keep up yet.
So we're just using progressive download with lighttpd right now.
The problem is, no matter how we even try to hid the playlist and
filename, the file just ends up in the user's browser cache if they know
where to look.
Basically, the idea I had was to use some sort of stream cipher on
the video. I could pre-encode them, and then serve them to the player.
Would it be possible, in flash, to have the player run that cipher back
over the video before playing? That way, without a lot of work, the
videos wouldn't play outside my player. It wouldn't necessarily need to
be real encryption either. If some sort of bit-shift or bit-mask would
be possible, that would work too.
I know it's sort of a dumb problem, but with the legal landscape the way
it is these days, I need to try to solve this.
Thanks in advance,
Alex Thurlwo
