[Python] from pytube import Playlist로 유튜브 영상 정보 확인

정보 받아서 출력

설명과 내용을 잘 담았군... 하필 링크를 애매한 걸 썼네 ㅋㅋㅋ

from pytube import Playlist

# 심층강화학습(Deep Reinforcement Learning)
url = 'https://youtube.com/playlist?list=PLalDxVXf3NHe8s6o7crR0F2yFKpGhNJZw'

playlist = Playlist(url)
print('동영상 재생목록 수: %s' % len(playlist.video_urls)) 
print('재생목록 제목: %s' % playlist.title) 
print('-------------------------------------------------\n')

def detail(yt, output):
    contents = {"조회수": yt.views, 
                "길이": yt.length, 
                "설명": yt.description
                }.get(output, "알 수 없습니다.") 
    print(f'\n제목>>> {yt.title} \n{output}>>> {contents}')
    
for video in playlist.videos:
    detail(video, "설명")

video라는 Playlist 객체에서 비디오가 어떻게 구성되어 있는지 확인 가능

streams는 Query 객체로 처리, all()이나 first()를 같이 사용해야 함
mp4 확장자만 추출하기 위해 filter()를 사용할 수 있음

for e in video.streams.filter(file_extension='mp4').all():
	print(str(e))

가장 아래를 보면 mime_type="video/mp4"와 mime_type="audio/mp4"를 확인할 수 있음 
"audio/mp4"는 음성만 있는 파일

<Stream: itag="22" mime_type="video/mp4" res="720p" fps="30fps" vcodec="avc1.64001F" acodec="mp4a.40.2" progressive="True" type="video">

비디오도 뭐는 acodec이 있고 뭐는 없음 
acodec이 없는 파일은 영상만 존재하는 파일(음성이 없음)
