GraphicsBuffer format

I hope that this is the right question to ask…

Does the information stored in the GraphicsBuffer correspond directly to either the RGB or the YUV formats? One of the things that I am wanting to do is to encode video direct from within the application itself.

Now, I COULD save the video as a series of Bitmaps but it would seem more efficient to me to be able to directly pass the GraphicsBuffer to the encoder.

Thankyou for your assistance.

The GraphicsBuffer stores RGB data.
