我们将在之前的代码基础上添加以下功能：
1. 开始监控按钮：点击后开始定时监控
2. 视频保存路径选项：让用户选择保存视频的文件夹
3. 音频提醒选择按钮：让用户选择自定义的提醒音频文件
修改步骤：
- 使用Tkinter的Button组件添加“开始监控”按钮
- 使用Button和filedialog添加保存路径选择
- 使用Button和filedialog添加音频文件选择，并存储音频文件路径
- 将定时任务绑定到开始监控按钮，点击按钮后启动定时检查
注意：由于抖音API可能变化，我们使用一个假设的`DouyinCrawler`类，实际使用时需要替换为有效的抖音视频获取方法。
代码结构：
1. 创建主界面，添加控件：
- 博主ID输入框
- 选择保存路径的按钮和路径显示
- 选择音频文件的按钮和路径显示
- 开始监控按钮
2. 实现路径选择函数和音频选择函数
3. 实现开始监控函数，在该函数中设置定时器，每隔一段时间检查更新
由于Tkinter的主循环是单线程的，定时任务使用`after`方法实现，避免使用`schedule`库（因为它在主线程中会阻塞）。
我们将使用Tkinter的`after`方法实现定时检查，例如每10分钟检查一次。
注意：无水印下载功能需要实现，这里使用伪代码，实际实现可能需要替换。
下面给出修改后的代码：

### 功能说明
1. **新增功能**：
- **开始/停止监控按钮**：控制监控任务的启动和停止
- 📂 **视频保存路径选择**：通过浏览按钮选择视频保存位置
- 🔊 **自定义提醒音频**：支持选择任意MP3/WAV文件作为提醒音
- 👤 **博主列表管理**：添加、移除监控的抖音博主
- ️ **配置自动保存**：程序关闭时自动保存设置
2. **使用流程**：
- 在"博主ID"输入框输入博主ID，点击"添加博主"
- 点击"浏览..."选择视频保存路径
- 点击"选择文件..."选择提醒音频
- 点击"开始监控"按钮启动监控
- 当博主更新作品时，程序会自动下载并播放提醒音
3. **注意事项**：
- 需要安装`douyin-private-api`库获取抖音数据
- 首次使用需安装依赖：`pip install requests pydub schedule`
- 音频播放需要安装FFmpeg（[下载地址](https://ffmpeg.org/)）
### 优化建议
1. **增加进度显示**：
```python
# 下载视频时增加进度条
from tqdm import tqdm
# 在download_video方法中
total_size = int(response.headers.get('content-length', 0))
progress = tqdm(total=total_size, unit='B', unit_scale=True)
with open(filepath, 'wb') as f:
for chunk in response.iter_content(chunk_size=1024):
if chunk:
f.write(chunk)
progress.update(len(chunk))
progress.close()
```
2. **多线程下载优化**：
```python
# 使用线程池提高下载效率
from concurrent.futures import ThreadPoolExecutor
def download_all_new_videos(self):
with ThreadPoolExecutor(max_workers=3) as executor:
futures = [executor.submit(self.download_video, video)
for video in new_videos]
```
3. **错误重试机制**：
```python
from tenacity import retry, stop_after_attempt, wait_fixed
@retry(stop=stop_after_attempt(3), wait=wait_fixed(2))
def download_video_with_retry(self, video_data):
self.download_video(video_data)
```
