I'm curious if it's possible for an flv file to contain code like ActionScript or if it can only contain the audio/video data for the video.
I'm specifically asking related to the security of allowing an FLV file to be uploaded a site.
Edit: assume that the contents have been validated to be a real "flv" - the question is whether the format natively supports code inside of the flv.

To that question, the answer is no. For further security discussions, see the other answers.
