yt-dlp를 사용하면 된다.

1. 설치

• FFmpeg에서 바이너리를 다운받거나 homebrew를 설치한다. (오디오랑 비디오를 하나로 합칠때 쓰인다)
• yt-dlp에서 바이너리를 다운받는다.

2. 다운로드

# mp4 형식으로 최대 길이 1080px 으로 영상 다운로드하기
yt-dlp -f "bv*[vcodec^=avc]+ba[ext=m4a]/b[ext=mp4]/b" --live-from-start wydBufD_8qQ

# webm 형식으로 원본 영상 다운로드하기 (추후 mp4으로 변환해야하는 번거로움이 있음)
yt-dlp -f "bv+ba/b" --live-from-start wydBufD_8qQ

3. 테스트

공돌이파파 is going live!를 한번 다운해보자.

yt-dlp -f "bv*[vcodec^=avc]+ba[ext=m4a]/b[ext=mp4]/b" --live-from-start m4SpqRWkvVg

속도도 준수하고 아주 좋다.

라이브가 아닌 영상도 다운로드 할 수 있다.

rock to infinity를 다운해보자.

--live-from-start 를 뺀 상태로 명령어를 호출하면 된다.

yt-dlp -f "bv*[vcodec^=avc]+ba[ext=m4a]/b[ext=mp4]/b" --download-sections "*00:32:53.2-00:32:55.5" e4Kw9ADHJZ8

이렇게 하면 특정 시간만 받을 수 있다!!

yt-dlp -f "bv*[vcodec^=avc]+ba[ext=m4a]/b[ext=mp4]/b" --download-sections "*07:29:35-07:32:40" e4Kw9ADHJZ8

아주 잘된다
