Flash Player Version Question

[mafordha]

Does anybody know of a way to figure out what version a SWF was published for. For example, how could I find out what Flash Player version YouTube has targeted for their video player? The player I have may be a more recent version.

Thanks for any advice!
Matt.

I dont think it really matters, it will just be slightly different byte code.

Even if you do compile to target fp10, it will still work in fp9 provided you don't use any of the new fp10 methods/features.

If you do attempt to run fp10 content in fp9, it will either error or won't display all the content.

There is a stage property, that has the flash player's version in it. (the clients version, not the compiled swf version.)
