I'd like to distribute FLV files from my website, however I want a level of DRM control over the files. So far, I've been able to modify the FLV files to contain a 60 character ID at the very front of the file, but I can't figure out how to get AIR to extract the ID and therefore play the file. All I can figure out is using NetStream, but that won't let me skip 60 bytes, and so it thinks the FLV is invalid.
Any ideas?
Thanks,
Mike Christopher
While this is not the answer you are looking for, and because I'm not running down some tech puzzle rabbit hole trying to help you figure out if you want to hammer in a nail with a glass bottle or a shoe, I'll probably get down-voted to all hell - but I feel a need to respond thus:
Maybe the problem is that you're relying on DRM to solve a business model issue. I'm assuming you are trying to ensure that someone doesn't pirate your videos and/or access them without paying. (please let me know if this is assumption is incorrect)
TechDirt has a number of posts relating to the issues of relying on DRM, and even if they didn't you have to have noticed that no DRM scheme ends up being successful for a meaningful amount of time. Odds are, most of those people wouldn't have bought it anyway. Maybe you need to look at ways of turning that pirated content into an effective way of attracting new customers.
Not knowing the particulars makes it kind of hard to give a specific answer, but even if you don't pursue it here, it would be worth setting up a case with the Insight Community over at TechDirt. Just a thought.
