我用过 youtube-dl从 YouTube 上抓取它。

我想将其转换为纯文本。我不能在文本重复时去掉时间和颜色标签。

所以我想知道是否存在将其转换为纯文本的东西，或者是否有人可以提供一些伪代码以便我可以对其进行编码？

我还通过 youtube-dl 发布了一个关于此的问题.

我用过 WebVTT-py提取纯文本转录。

import webvtt
vtt = webvtt.read('subtitles.vtt')
transcript = ""

lines = []
for line in vtt:
    # Strip the newlines from the end of the text.
    # Split the string if it has a newline in the middle
    # Add the lines to an array
    lines.extend(line.text.strip().splitlines())

# Remove repeated lines
previous = None
for line in lines:
    if line == previous:
       continue
    transcript += " " + line
    previous = line

print(transcript)
