I am able to play back and read this metadata with my own simple player but as soon as I do any thing with ffmpeg (even a copy) this custom metadata is gone. I was expecting a simple fly to flv to work.

Any one have an idea if flash/flv custom metadata can survive FFMPEG? i not talking about create by etc  metadata but custom. Even a yes or no would helpful but if you the know syntax that would be great. Thank you..
