Sorry, I am not sure which macro to use in this case.
My comment is not very good, in fact on some cameras I need to swap the bytes
to have correct JPEG data (so this is not an endianness issue I think).
Maybe there is a macro to swap bytes in a buffer? I cannot find it.
Thanks for your comments and best regards,
Antoine
