У меня есть сценарий, который загружает список воспроизведения с информацией о видео в виде файла json.
Вчера я получил описание видео с \n символами новой строки, но сегодня эти новые строки теперь являются просто пробелом и извлеченными описание усечено. Я не помню никаких изменений в моем коде и обновлений до youtube-dl.
Youtube что-то изменил? Или я где-то ошибся?
Python 3.8.1, youtube-dl 2020.6.16.1
Вот код, который в настоящее время извлекает описание видео без символов новой строки.
import youtube_dl
import json
ydl_opts = {
'ignoreerrors': True,
}
urls = ['http://youtu.be/wFWihZTktUw', 'http://youtu.be/QvuQH4_05LI']
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
print('Extracting playlist info...')
playlist_info = []
for idx, url in enumerate(urls):
video_info = ydl.extract_info(url, download=False)
if not video_info:
continue
properties = ['title', 'id', 'description']
for k in list(video_info.keys()):
if k not in properties:
del video_info[k]
playlist_info.append(video_info)
with open(f'playlist_info.json', 'w') as fp:
json.dump(playlist_info, fp)
