# B 站视频转录 Skill

**字幕优先**:先尝试抓取官方/自动字幕(秒级、免 GPU、免 funasr);抓不到再下载音频用 SenseVoice-Small 转录,存为 Markdown 文件。加 `--no-subtitle` 可强制走音频转录。

## 环境要求

```bash
# Python 3.9+
python -m venv .venv
source .venv/bin/activate

# 依赖
pip install funasr modelscope torch torchaudio

# 系统依赖
# macOS: brew install ffmpeg yt-dlp
# Ubuntu: sudo apt install ffmpeg && pip install yt-dlp
```

## 使用方法

```bash
python scripts/transcribe.py "https://www.bilibili.com/video/BV1rrQGBeEen/"
python scripts/transcribe.py "BV1rrQGBeEen"
python scripts/transcribe.py "BV1rrQGBeEen" --no-subtitle   # 强制音频转录

# 批量处理:每行一个 B站 URL 或 BV 号
python scripts/batch_transcribe.py urls.txt -o ./output
```

## 流程

### Step 1: yt-dlp 下载音频

B 站有反爬机制,需要加 User-Agent 和 Referer:

```bash
yt-dlp --extract-audio --audio-format mp3 --audio-quality 128K \
  --user-agent "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) ..." \
  --referer "https://www.bilibili.com" \
  "https://www.bilibili.com/video/BV1rrQGBeEen/"
```

### Step 2: SenseVoice-Small 转录

```python
from funasr import AutoModel
from funasr.utils.postprocess_utils import rich_transcription_postprocess

model = AutoModel(
    model="iic/SenseVoiceSmall",
    trust_remote_code=True,
    vad_model="fsmn-vad",
    vad_kwargs={"max_single_segment_time": 30000},
    device="cpu",
)

result = model.generate(input=audio_path, language="zh", use_itn=True, batch_size_s=60)
```

### Step 3: 生成 Markdown

自动创建带 frontmatter 的 Markdown 文件。

### 批量模式

`scripts/batch_transcribe.py` 会逐条调用单篇转录脚本,默认单条失败后继续处理下一条;需要严格模式时加 `--stop-on-error`。

## 性能数据
