What are the magic bytes for .yuvn files?
The magic bytes for YUVN files are 46 4F 52 4D 59 55 56 4E at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .yuvn file?
To validate a .yuvn file, read the first bytes of the file and compare them against the known magic bytes (46 4F 52 4D 59 55 56 4E) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .yuvn files?
There is no officially registered MIME type for .yuvn files. Systems typically use application/octet-stream as a generic fallback when handling this format.
