# 视频/播客
|
||
|
||
YouTube、B站、小宇宙播客的字幕和转录。
|
||
|
||
## YouTube (yt-dlp)
|
||
|
||
### 获取视频元数据
|
||
|
||
```bash
|
||
yt-dlp --dump-json "URL"
|
||
```
|
||
|
||
### 下载字幕
|
||
|
||
```bash
|
||
# 下载字幕 (不下载视频)
|
||
yt-dlp --write-sub --write-auto-sub --sub-lang "zh-Hans,zh,en" --skip-download -o "/tmp/%(id)s" "URL"
|
||
|
||
# 然后读取 .vtt 文件
|
||
cat /tmp/VIDEO_ID.*.vtt
|
||
```
|
||
|
||
### 获取评论
|
||
|
||
```bash
|
||
# 提取评论（best-effort，不保证完整）
|
||
yt-dlp --write-comments --skip-download --write-info-json \
|
||
--extractor-args "youtube:max_comments=20" \
|
||
-o "/tmp/%(id)s" "URL"
|
||
# 评论在 .info.json 的 comments 字段中
|
||
```
|
||
|
||
### 搜索视频
|
||
|
||
```bash
|
||
yt-dlp --dump-json "ytsearch5:query"
|
||
```
|
||
|
||
> **字幕注意**: 手动上传的字幕提取可靠；自动生成字幕可能存在行间重复，需后处理。
|
||
> **评论注意**: `--write-comments` 基于网页抓取（非 YouTube Data API），部分评论可能丢失。
|
||
