Moyea FLV Downloader is a program for downloading FLV videos with support for the most popular sites that offer streaming content like YouTube, Dailymotion, MySpace, etc. Meanwhile, it allows you to manage your downloads/conversions with multiple options. This FLV video downloader also includes a built-in FLV converter so you can download and convert videos to other popular formats such as FLV to MP3 and more. Apart from FLV Downloader, FLV.com provides an FLV player, which is designed for playing FLV videos. Don't bother, I can't-it was for a proprietary project for my employer, xtendx AG.FLV Downloader from FLV.com is a free application that helps you save online videos from over 50 video sites (YouTube, Vimeo, Yahoo Video, Dailymotion, etc.). It is amazing how many "plz sends me teh codez" emails this post has generated from the "simple, custom one-time authentication mechanism" suggestion. Not even a power users is capable of beating it. I've actually implemented that last idea, the authorization mechanism, myself and can vouch for it's practical effectiveness. authorization key matches to content key in server side store.Server sends ´FLV´ content to client if and only if.Player requests content a with authorization2.Server stores content key, authorization1 key, authorization2 key (which is SHA1( authorization1 + salt2)).Server returns an authorization1 key: SHA1(content key + salt1).Player requests authorization key for content A.

Set aggressive 'don't cache' headers for all your FLV content.

Additionally, once the file is saved to disk, a non-FLV player will open it (and complain about it being an invalid file format.) Again, Flash players blissfully ignore it anyway. Flash players blissfully ignore it anyway.

Change/remove the MIME type the server is responding with.

A dedicated hacker will get to it, but most folks are just script kiddies (or their FireFox plug-in loving cousins.) Plus, some of these techniques are really easy: These aren't full proof mechanisms, but very well may prevent 80%-99% of people trying to copy your FLV streams/files. There are a couple of obfuscation techniques that may meet you needs. I fully agree with the DRM consensus of other answers.
