Хочу скачать видео с ютуба и конвертировать его в аудио. Для этого использую библиотеку youtube-dl. В моём коде простой пример из
документации . Установленные пакеты: pip install youtube-dl, ffmpeg
from __future__ import unicode_literals
import youtube_dl
import ffmpeg
ydl_opts = {
'format': 'bestaudio/best',
'postprocessors': [{
'key': 'FFmpegExtractAudio',
'preferredcodec': 'mp3',
'preferredquality': '320',
}],
'prefer_ffmpeg': True
}
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
ydl.download(['https://www.youtube.com/watch?v=BaW_jenozKc'])
Результатом скачивается видео и конвертируется в аудиофайл, но при этом возникает очень много ошибок. Что не так?
WARNING: BaW_jenozKc: writing DASH m4a. Only some players support this container. Install ffmpeg or avconv to fix this automatically.
