Flash.net.netStream has an undocumented field called "decodedFrames" (which I discovered by reading someone's blog) This value is supposed to show how many frames have been decoded so far.

I wonder, since this is an undocumented field, can I rely on the correctness of this value?

Also, why isn't this documented? --I asked this question in the adobe's forum, but it seems like nobody is answering questions there. I hope someone knows the answer here.

Finally, if I am not supposed to rely on this value, what is the alternative to get this value?

This is flash's documentation on NetStream : http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/NetStream.html

Yes. It does not fake the results...

Also, why isn't this documented?

Because its only guaranteed to work correctly on desktops (not sure if mobile support has since been added)

Finally, if I am not supposed to rely on this value, what is the alternative to get this value?

Not much. You could try using netStream.time and assume if time is higher then frames must be decoded too. This measures time traveled within the video so you can break it down into frames if you wanted.
