구차니의 잡동사니 모음

최대한 땡겨서 찍었는데 미묘하다 미묘해..

고추아래에 달린.. 정체 불명의 곰팡이(by 아들) vs 우담바라!(by 아빠)

크랍..

머.. 별건 없지만 허전하니? ㅋ

docker라는 가상화 어쩌구를 통해 설치 하는것 같아서.

ds215+에서는 미지원.. 흐음..

native하게 설치할 수 있으려나

ruby는 어짜피 지원하니.

테스트 해보니 -g 1 만 i-frame으로 도배해서 좀더 빠르게 나오고

-ih는 팟플레이어 에서 영향을 주지 못한다.

무슨 옵션을 주던.. vlc에서는 안되네..

도대체 무슨 에러일까...

팟 플레이어에서 비트레이트가 0으로 뜨는거랑 연관이 있는걸까?

raspivid 관련 옵션을 보니

gop 설정과 PPS/SPS 헤더를 넣는게 있는데

gop야.. i frame 이라.. 이게 많으면 화질 좋아지고 용량 넘쳐나고, 재생 바로바로 되고 하지만

PPS/SPS의 경우에는 메타데이터라.. 이걸 통해 빠르게 재생 된다는 이야기도 있네...

--inline,   -ih     Insert PPS, SPS headers

Forces the stream to include PPS and SPS headers on every I-frame. Needed for certain streaming cases. e.g. Apple HLS. These headers are small, so do not greatly increase file size.

-t, --timeout   : Time (in ms) before takes picture and shuts down (if not specified, set to 5s)

기본값이 5초라서

사진 하나 받아오는데 항상 5초 걸리는 기분..

-t 0 는 안되므로

-t 1 이상은 설정을 해야 한다.

pi@raspberrypi:~/Pictures $ time raspistill -o tt.jpg -t 1

real    0m0.778s

user    0m0.010s

sys     0m0.030s

pi@raspberrypi:~/Pictures $ time raspistill -o tt.jpg -t 1000

real    0m1.948s

user    0m0.020s

sys     0m0.040s

받아오는 해상도 별로 시간 차이는 없음.

-tl, --timelapse        : Timelapse mode. Takes a picture every <t>ms. %d == frame number (Try: -o img_%04d.jpg)

그나저나 타임랩스 기능이 있네?

브라우저간 끌어 놓기는 IE10 부터 사용이 가능하다.

버그인진 모르겠지만.. IE 에서는 edge이던 10이던 해당 설정 체크 자체가 활성화 되지 않는다.

이렇게 보니.. 리눅스 버전이 미친듯이 올랐구나 싶네
