[Libav-user] Macroblock pixel's values

[NDJORE BORIS]

Hello all,

I want to know if it is possible to have YUV value for a given macroblock
in a
yuv420p frame. If yes, please tells me how we can do it.

In details what I want to do is the following :
I have an AVFrame F1.
In this frame F1, I have macroblocks MB1, MB2 and ...
I want to have the Y, u and v value of MB1, Y, u and v for MB2 and ...
If is possible to have Yuv value as a single int or char it will be good.

Regards.
