How to validate .vob files in Python

Python
def is_vob(file_path: str) -> bool:
    """Check if file is a valid VOB by magic bytes."""
    signature = bytes([0x00, 0x00, 0x01, 0xBA])
    with open(file_path, "rb") as f:
        return f.read(4) == signature

How to validate .vob files in Node.js

Node.js
function isVOB(buffer: Buffer): boolean {
  const signature = Buffer.from([0x00, 0x00, 0x01, 0xBA]);
  return buffer.subarray(0, 4).equals(signature);
}

How to validate .vob files in Go

Go
func IsVOB(data []byte) bool {
    signature := []byte{0x00, 0x00, 0x01, 0xBA}
    if len(data) < 4 {
        return false
    }
    return bytes.Equal(data[:4], signature)
}
