[FFmpeg-devel] Help with AVPicture

I've been trying to find a good way to get a certain amount of pixels from a 
jpeg image (such as 128x128 pixels from a 128x1920 jpeg image), but I don't 
know which way would be best. I was considering letting the mjpeg decoder 
first decode the jpeg and put it in an AVPicture struct, and then getting the 
data from the struct that I need (such as the 128x128 pixels) and return that 
data as a frame in my decoder. But, I don't know if that would work. 
Therefore, I am wondering (1) if it's possible to do that, and (2) how would I 
do it? Anyway, thanks alot! :-)
