How to validate .mxf files in Python

Python 
def is_mxf(file_path: str) -> bool:
    """Check if file is a valid MXF by magic bytes."""
    signature = bytes([0x06, 0x0E, 0x2B, 0x34, 0x02, 0x05, 0x01, 0x01, 0x0D, 0x01, 0x02, 0x01, 0x01, 0x02])
    with open(file_path, "rb") as f:
        return f.read(14) == signature

How to validate .mxf files in Node.js

Node.js 
function isMXF(buffer: Buffer): boolean {
  const signature = Buffer.from([0x06, 0x0E, 0x2B, 0x34, 0x02, 0x05, 0x01, 0x01, 0x0D, 0x01, 0x02, 0x01, 0x01, 0x02]);
  return buffer.subarray(0, 14).equals(signature);
}

How to validate .mxf files in Go

Go 
func IsMXF(data []byte) bool {
    signature := []byte{0x06, 0x0E, 0x2B, 0x34, 0x02, 0x05, 0x01, 0x01, 0x0D, 0x01, 0x02, 0x01, 0x01, 0x02}
    if len(data) < 14 {
        return false
    }
    return bytes.Equal(data[:14], signature)

Frequently Asked Questions

What is a .mxf file?

What are the magic bytes for .mxf files?

The magic bytes for Material Exchange Formatfile files are 06 0E 2B 34 02 05 01 01 0D 01 02 01 01 02 at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.

How do I validate a .mxf file?

To validate a .mxf file, read the first bytes of the file and compare them against the known magic bytes (06 0E 2B 34 02 05 01 01 0D 01 02 01 01 02) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.

What is the MIME type for .mxf files?

There is no officially registered MIME type for .mxf files. Systems typically use application/octet-stream as a generic fallback when handling this format.
