1st option: the samples we have contains vital metadata (image size) in EXIF fields. It would not help if you just prepend arbitrary JPEG at start.
2nd option (backport from patched dcraw): looks OK, but there is a lot of code covering multiple cases. It is not possible to move on without having sample files for all these multiple cases.
We are ready to go this route, but someone should prepare (various) examples
