Realsense Snapshot jpg Format

I know this is not the correct forum for the realsense snapshot, but it seems there is no separate category for it.

I'm trying to parse the jpg images the realsense snapshot creates on the dell v8 android tablet. It seems that there is a lot of exif sections in there (ranging from calibration to the recitified images), but i could not find any documentation for the file format they are using.

I've found the documentation for the intel depth format xbm (http://humphrey46.rssing.com/chan-21504803/latest.php), but it seems that they are using a different format here...

Does anyone have experience with the jpg containers of realsense snapshot images? That would help a lot...
 

Thanks for any direction you can point me to, it's quite frustrating working with the realsense snapshot...

They use Adobe XMP metadata to encode everything on a normal jpg file.

If you ignore the metadata, it is just an image. But the metadata contain a lot of info such as depth images, calibration parameters, etc.

Have a look here:

Thank you. I've been able to extract all the separate camera images from the jpg. They are stored rectified in blocks with length FFFD which you have to put together again. It's a bit weird but it worked.
