What are the magic bytes for .mlv files?
The magic bytes for MLV files are 4D 4C 56 49 at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .mlv file?
To validate a .mlv file, read the first bytes of the file and compare them against the known magic bytes (4D 4C 56 49) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .mlv files?
There is no officially registered MIME type for .mlv files. Systems typically use application/octet-stream as a generic fallback when handling this format.
