前提条件
非常抱歉,这个程序就是个雏形,非常不完善,输入需要手动编辑,凑活着可以用,请自己完善吧。
开源声明:此文代码引用了一个开源MIT License的Python库,其他代码是本人自写自用。你可以随便用,但是本人不负责有关代码的任何责任。
概述
输入:油管英文视频的视频号 例如 "04j_yB4CZPM"
输出:两个srt文件
- 手动英文(没有则是自动英文)srt 字幕,即eng.srt
- 自动中文简体翻译srt字幕,即zh.srt
核心开源库 (开源的MIT License授权,不存在版权问题,请审核放行!!!)
核心思想是用到了开源的MIT License的 youtube_transcript_api 这个库来为我们服务。其中,用了YouTubeTranscriptApi, 用于获取字幕。
也用到了 其中 formatters 子库里面的 SRTFormatter,用于将字幕转化为srt格式。

代码正文开始,先引用开源库
python
from youtube_transcript_api import YouTubeTranscriptApi
# the base class to inherit from when creating your own formatter.
from youtube_transcript_api.formatters import Formatter
# some provided subclasses, each outputs a different string format.
from youtube_transcript_api.formatters import JSONFormatter
from youtube_transcript_api.formatters import TextFormatter
from youtube_transcript_api.formatters import WebVTTFormatter
from youtube_transcript_api.formatters import SRTFormatter
设定油管视频号(你需要改成你的视频号)
python
vid = "04j_yB4CZPM" #think twice before drink milk```
获取字幕列表
python
transcript_list = YouTubeTranscriptApi.list_transcripts(vid)
尝试提取手动英文字幕,没有则提取自动英文字幕,因为手动字幕一般来说,质量更高
python
try:
transcript = transcript_list.find_manually_created_transcript(['en'])
except:
try:
# or automatically generated ones
transcript = transcript_list.find_generated_transcript(['en'])
except:
print("cannot find auto en")
ten = transcript.fetch()
提取自动翻译的中文字幕。注意:这里有完善的机会,你可以优先获取手动中文字幕,如果没有,再获取翻译中文简体字幕。因为在我的使用场景,很少有手动中文字幕,所以,这里我就直接先照顾我自己的使用场景了。
python
translated_transcript = transcript.translate('zh-Hans')
tzh = translated_transcript.fetch()
把英文、中文字幕转化为srt格式
python
formatter = SRTFormatter()
srt_formatted_en = formatter.format_transcript(ten)
srt_formatted = formatter.format_transcript(tzh)
英文字幕保存为文件
python
with open(r"eng.srt", "w+", encoding='utf-8') as fen:
for sfen in srt_formatted_en:
fen.write(sfen)
fen.close()
中文字幕保存为文件
python
with open(r"zh.srt", "w+", encoding='utf-8') as f:
for sf in srt_formatted:
f.write(sf)
f.close()
我承认,有很多需要完善的地方,但是对我日常工作而言,已经够用了。抛砖引玉,请大家继续努力吧。
加油好运!
