[Libav-user] AVColorSpace processed by libav?

I recently stumbled into AVColorSpace and the corresponding variables 
inside the AVCodecContext, as well as the frame functions to retrieve 
the color space.
My question is the following:  Are these color spaces used by libav in 
any shape or form or are they hints to the decoding party on how to 
display the images?
I ask because I tried muxing a BT709 movie file and the result was the 
same as without the tag.
