[Libav-user] Detecting image orientation in pictures from a camera?

I've got a series of images taken with a camera that I need to process with
libav*. Is there any way to check the EXIF data to determine
rotation/orientation for the image (so that I can rotate it in my program)?

When I print out the metadata for the AVFormatContext, AVStream, and
AVFrame, they're all empty, and beyond that I'm not sure where to look.
