I'm not an expert either but i don't think that going
back to RGB is a good choice.YCbCr (4:2:2) already
achieves some compression. If you convert it back to
RGB and then perform a Jpeg compression you degrade
the samples even more than the original YCbCr has
already done. A Jpeg compression at some point needs
to get the YCbCr samples themselves.

Hi,conversion
I am not sure you have solution other than doing the YCbCr to RGB
by yourself and thus create the bitmap that will feed the interface you
described. You will find valuable information on the Internet by Googling
"yuv rgb" or "yuv2rgb".
However, I am not an expert and if there is one, I am as interested as you
in the solution :-)
