### Install pydvdid using pip

Source: https://pypi.org/project/pydvdid

Install the pydvdid package using pip. This is the standard way to install Python packages.

```bash
pip install pydvdid
```

### Retrieve DVD metadata using curl

Source: https://pypi.org/project/pydvdid

Use the obtained CRC64 to query the Windows Media Services API for DVD metadata. This example demonstrates how to fetch XML data containing DVD title and other details.

```bash
steve@babbage:~$ curl --get http://metaservices.windowsmedia.com/pas_dvd_B/template/GetMDRDVDByCRC.xml?CRC=$crc64
<?xml version='1.0' encoding="UTF-8" ?><METADATA xmlns:sql="urn:schemas-microsoft-com:xml-sql">

### Get DVD CRC from shell

Source: https://pypi.org/project/pydvdid

Calculate the CRC64 for a DVD mounted at /mnt/dvd and store it in a shell variable. This CRC can then be used for metadata retrieval.

```bash
steve@babbage:~$ crc64=$(pydvdid /mnt/dvd)
steve@babbage:~$ echo $crc64
6e23e6a41a154405
```

### Compute DVD ID and Fetch Metadata

Source: https://pypi.org/project/pydvdid

Import the compute function from pydvdid to generate a CRC64 hash for a DVD directory. This hash can then be used to query for DVD metadata from a remote service.

```python
>>> from pydvdid import compute
>>> crc64 = compute("/mnt/dvd")
>>> str(crc64)
'a5acf20f2e56954b'
```

```python
>>> from urllib import urlopen
>>> urlopen("http://metaservices.windowsmedia.com/pas_dvd_B/template/GetMDRDVDByCRC.xml?CRC={0}".format(crc64)).read()
