- 顯示所有可用格式
yt-dlp -F 「影片網址」
- 私人影片下載指定格式 並從firefox 讀取cookie , 使用不常用的browser 並在下載後登出避免cookie被濫用 chrome and safari 容易有權限問題故使用firefox
yt-dlp --cookies-from-browser firefox 「影片網址」 -f 271+251
import yt_dlp
yt_opts = {
'format': 'bestvideo+bestaudio/best',
'outtmpl': '%(title)s.%(ext)s',
'embed_thumbnail': True,
'add_metadata': True,
'merge_output_format': 'mp4'
}
with yt_dlp.YoutubeDL(yt_opts) as ydl:
ydl.download(['影片網址'])
僅下載音訊
yt-dlp --output "%(title)s.%(ext)s" --embed-thumbnail --add-metadata --extract-audio --audio-format mp3 --audio-quality 320K 「影片網址」
直接下載不轉換
yt-dlp --cookies-from-browser firefox "https://www.youtube.com/watch?v=xxxxxxxxxx" -f 599
使用程式下載
import yt_dlp
