VideoVCD (.vcd)

.vcd file signature | application/x-cdlink

VideoVCD is a Video CD image format created and maintained by the GNU VCDImager project. It is used to store disc images for authoring, testing, and burning Video CD media, including MPEG-1 video content and related disc structure. As a legacy optical-disc format, it is generally safe to inspect, though its usefulness is limited by the decline of Video CD playback hardware.

How to validate .vcd files in Python

Python
def is_vcd(file_path: str) -> bool:
    """Check if file is a valid VCD by magic bytes."""
    signature = bytes([0x45, 0x4E, 0x54, 0x52, 0x59, 0x56, 0x43, 0x44, 0x02, 0x00, 0x00, 0x01, 0x02, 0x00, 0x18, 0x58])
    with open(file_path, "rb") as f:
        return f.read(16) == signature

How to validate .vcd files in Node.js

Node.js
function isVCD(buffer: Buffer): boolean {
  const signature = Buffer.from([0x45, 0x4E, 0x54, 0x52, 0x59, 0x56, 0x43, 0x44, 0x02, 0x00, 0x00, 0x01, 0x02, 0x00, 0x18, 0x58]);
  return buffer.subarray(0, 16).equals(signature);
}

How to validate .vcd files in Go

Go
func IsVCD(data []byte) bool {
    signature := []byte{0x45, 0x4E, 0x54, 0x52, 0x59, 0x56, 0x43, 0x44, 0x02, 0x00, 0x00, 0x01, 0x02, 0x00, 0x18, 0x58}

Frequently Asked Questions

What is a .vcd file?

A .vcd file is a VideoVCD file. VideoVCD is a Video CD image format created and maintained by the GNU VCDImager project. It is used to store disc images for authoring, testing, and burning Video CD media, including MPEG-1 video content and related disc structure. As a legacy optical-disc format, it is generally safe to inspect, though its usefulness is limited by the decline of Video CD playback hardware.

What are the magic bytes for .vcd files?

The magic bytes for VideoVCD files are 45 4E 54 52 59 56 43 44 02 00 00 01 02 00 18 58 at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.

How do I validate a .vcd file?

To validate a .vcd file, read the first bytes of the file and compare them against the known magic bytes (45 4E 54 52 59 56 43 44 02 00 00 01 02 00 18 58) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.

What is the MIME type for .vcd files?

The primary MIME type for .vcd files is application/x-cdlink.

Is it safe to open .vcd files?

VideoVCD (.vcd) files are generally safe to open. They are classified as low risk because they primarily contain data rather than executable code. However, always ensure files come from a trusted source.
