주 :
- 25 fps 컨텐트에서만 작동.
- 30/40/50 Mbps D10 essence를 위해서 minrate, maxrate 과 b 값을 30000k / 40000k / 50000k 으로 설정.
- 30/40/50 Mbps D10 essence를 위해서 bufsize와rc_init_occupancy 값을 1200000 / 1600000 / 2000000 으로 설정.
- 720x576 소스에서 720x608 D10 이미지로 크기를 변경하고자 하면 -padtop 32 옵션을 추가.
주 :
- 이 특징은 패치된 FFmpeg 버전을 필요로 한다. 현 SVN에는 유효하지 않다. 더 많은 정보는 Baptiste Coudurier으로 연락하세요.
- D10 30/40/50 PAL를 위해서는 -vtag to mx3p / mx4p / mx5p 을 설정 혹은, D10 30/40/50 NTSC를 위해서는 mx3n / mx4n / mx5n 를 설정.
- 입력 D10 이미지 크기는 반드시 720x608이어야 함. ( D10으로 인코딩할 경우 원본 이미지 크기가 720x576이라면 -padtop 32 옵션을 사용하다..
- Final Cut Pro 용도.
type VTS_01_1.VOB VTS_01_2.VOB VTS_01_3.VOB | ffmpeg -i - -sameq -an -f avi output.avi
주: type은 도스에서 파일 내용을 화면에 표시하는 명령어. 리눅스에서 한다면 cat를 사용하면 된다.
"-i"옵션에 "-"은 파이프 통해서 수신받는다는 의미.
주: 특정 파일들은 연속해서 처리하지 못하네요. youtube에 여러 개로 불리된 동영상을 받아서 하나로 합치는 중에 처음 파일만 인코딩되고 나머지 파일은 안되는 문제가 있네요. 개별적으로는 이상이 없네요. 위의 옵션은 VOB파일 테스트시 이상없이 잘 되었던 옵션입니다.
Tip: 팁이라고 할 것은 없고, 다른 flv, avi 같은 여러 파일을 하나로 합칠려고 바로 위의 옵션을 사용하면 안된다. 먼저 flv나 avi를 VOB로 변화시키고, 그런 다음에 위의 명령을 이용하여 VOB파일들을 합치면 된다. 그러면 자동적으로 flv나 avi의 인코딩 타입도 같은 옵션으로 변경되어 VOB로 잘 합쳐지게 될 것입니다.
특정 폴더에 있는 모든 파일을 인코딩 배치 처리
for /f "usebackq tokens=1,2* delims=." %i in (`dir /b /d *.wma`) do ffmpeg -i "%i.%j" -y -acodec libmp3lame -ab 128k "%i.mp3"
주: MS 도스창에서 유효한 옵션입니다. 리눅스 쉘에서는 쉘 스크립트로 재 작성해야 합니다. 수정할 부분은 다음과 같네요.
*.wma : 인코딩하고 싶은 동영상 파일에 대한 필터(ex. *.wma - 확장자가 wma인 모든 파일, abc*.avi - 첫음 abc로 시작하는 모든 avi 파일)
ffmpeg 옵션: 이부분은 위의 옵션을 참조하세요.
수정이력:
2008.10.29 ospace 초벌 번역, 대충 한번 번역함(ospace).
2008.11.11 ospace 중간 번역 완료, flag, subcmp 옵션을 제외하고는 거의 대부분 변역 완료(ospace).
2008.11.19 ospace "여러 파일을 하나로 연속해서 비디오 파일생성" 부분 추가, 비디오 인코더 libxvid 주석 추가.
2008.12.01 ospace 작업 중인 버전정보추가. 기본 옵션 순서를 ffmpeg 도움말 순서에 맞춤. 추가 옵션 내용 추가하고 일부 해석.
2008.12.11 ospace 여러 파일 합치는 부분 문제 이슈 등록과 잘못된 "주" 위치 수정.
2008.12.11 ospace 인코딩 배치 처리 부분의 설명 추가
2009.11.05 ospace 추가된 옵션과 새로운 도움말에 맞춰서 순서 재구성 및 format, codec을 따로 분리 표시
2009.11.10 ospace 새로 추가된 옵션 일부 번역. 중요하지 않은 옵션 항목들은 펼침항목으로 묶음. 여러 파일 합치는 것에 팁 추가
TODO:
-. 각 잘 모르는 용어에 대한 간단한 주석이 필요 (GOP etc).
-. 사용 예에 대한 옵션 설명이 필요.
-. 추가된 옵션에 대해서 번역 필요
