I’ve been shopping for something that does a per-byte description of the content of visual media formats (jpeg, png, avi, mp4, etc). Anyone know of one?
I want to drop a specific image in, and have a reader that debugs this.
Sometimes images don't follow specs exactly, or stretch them in fun ways, and sometimes this leads to inconsistent behaviour across platforms. Sometimes passing an image through a platform strips or reformats this data.
The current context for me is I'm exploring various non-steganography approaches to embed metadata in photos. In the past, I've built custom formats to embed streaming data side-by-side: https://github.com/dustinfreeman/kriffer
