# YouTube 下載器 (yt\_dlp) 集成

了解如何將 yt-dlp 與高帶寬代理集成，以實現高效的 YouTube 影片和音訊抓取。本文包含命令行範例及為每次下載使用獨立 IP 的技巧。

### 示例整合：YouTube 下載器

以下是一個使用 yt-dlp 配合我們的高頻寬代理進行視訊或音訊數據抓取的示例：

#### 基本用法

{% tabs %}
{% tab title="Command Line" %}

```sh
yt-dlp --proxy username:password@endpoint:9999 \
"https://www.youtube.com/watch?v=WNCl-69POro"
```

{% endtab %}

{% tab title="Python" %}

```python
import yt_dlp

username = 'YOUR_USERNAME'
password = 'YOUR_PASSWORD'

proxy = f'http://{username}:{password}@endpoint:9999'

ydl_opts = {
    'proxy': proxy,
}

with yt_dlp.YoutubeDL(ydl_opts) as ydl:
    ydl.download(['https://www.youtube.com/watch?v=WNCl-69POro'])
```

{% endtab %}
{% endtabs %}

{% hint style="info" %}
為確保最佳效能，請確認每個視頻均透過獨立的IP地址進行下載。具體操作指南請參閱下方章節。
{% endhint %}

#### **使用不同IP處理多個URL**

使用高頻寬代理時，每個影片都會透過獨立的IP地址進行下載，以確保最佳性能。這是透過為每個請求生成唯一會話ID來實現的，該機制會為每次下載動態分配新的IP地址。

{% tabs %}
{% tab title="Command Line" %}

```sh
# First video with one IP
yt-dlp --proxy username-sessid-your_sessid-sesstime-your_sesstime:password@endpoint:9999 \
"https://www.youtube.com/watch?v=6stlCkUDG_s"

# Second video with different IP
yt-dlp --proxy username-sessid-your_sessid-sesstime-your_sesstime:password@endpoint:9999 \
"https://www.youtube.com/watch?v=gsnqXt7d1mU"
```

{% endtab %}

{% tab title="Python" %}

```python
import yt_dlp


def download_with_new_ip(url, username, password):
    sessid = "your-sessid"
    sesstime = "your-sesstime"
    proxy = f'http://{username}-sessid-{sessid}-sesstime-{sesstime}:{password}@your-endpoint:9999'

    ydl_opts = {
        'proxy': proxy
    }

    with yt_dlp.YoutubeDL(ydl_opts) as ydl:
        try:
            print(f"Downloading {url} with new IP ({username}-sesstime-10)...")
            ydl.download([url])
            print(f"Successfully downloaded {url}")
        except Exception as e:
            print(f"Error downloading {url}: {str(e)}")


def main():
    username = 'YOUR_USERNAME'
    password = 'YOUR_PASSWORD'

    videos = [
        'https://www.youtube.com/watch?v=_SdpvpvVrLY',
        'https://www.youtube.com/watch?v=2LEgs_H2gYg'
    ]

    for video in videos:
        download_with_new_ip(video, username, password)


if __name__ == "__main__":
    main()
```

{% endtab %}
{% endtabs %}

{% hint style="info" %}
該功能包含基礎性錯誤處理機制，即使單次下載失敗，仍能確保持續運行。
{% endhint %}
