라즈베리 파이 CSI / uv4l2 / MMAL / motion

bcm2835-v4l2 모듈만 불러주면 해결

(테스트 라즈비안 2015.5.5일자 클린상태)

uv4l2를 설치해서 되는건진 테스트 필요 (sd 밀고 다시 설정하고.. 아으 ㅋㅋㅋㅋ)

$ sudo apt-get install uv4l uv4l-raspicam uv4l-raspicam-extras uv4l-server uv4l-uvc uv4l-xscreen uv4l-mjpegstream

Camera Enable로 설정 후 재부팅

$ sudo raspi-config

만약 start_x를 추가하지 않아 카메라가 활성화 되지 않으면

움직임 감지시 이미지로 저장하는 부분

output_normal을 off로 하면 "target_dir" 에 저장을 하지 않음

움직임 감지시 동영상 저장 부분. swf가 기본값이며 ffmpeg_cap_new를 off로 해주면 저장되지 않았다.

(기본값이 off라면서 on이 되어 있냐 -_-)

motion.conf I ended up commented these out when i was testing but not totally sure if it helped. It's prolly ok to leave motion.conf pretty much as it was but this works fine for me and that's how it's gonna stay now it's fully working. ;netcam_url value ;target_dir value ;webcam_port 8081 ;videodevice /dev/video0 [링크 : http://ubuntuforums.org/showthread.php?t=1897786]

화면이 안떠서 디버깅을 해보니 예제로 된 /etc/motion/motion.conf 에서

thread의 경로가 잘못 잡힌 것을 발견

$ sudo motion[0] Processing thread 0 - config file /etc/motion/motion.conf [0] Thread config file /usr/local/etc/thread1.conf not found: No such file or directory [0] Thread config file /usr/local/etc/thread2.conf not found: No such file or directory [0] Motion 3.2.12 Started [0] Motion going to daemon mode

이렇게 하니.. 8081 8082 포트로 접속이 된다.

$ sudo vi /etc/motion/motion.conf # thread config files. thread /etc/motion/thread1.conf thread /etc/motion/thread2.conf ; thread /usr/local/etc/thread3.conf ; thread /usr/local/etc/thread4.conf

8080 에서는 작동중인 쓰레드가

8081 에는 cam1

8082에는 cam2

15 프레임 캡쳐 / 15 프레임 스트리밍 해둔건데 cpu가 1개 코어 100%를 먹네.. ㄷㄷㄷ

그나저나 아이패드에서는 영상이 가로/세로 바꾸거나 스크롤을 하는 동안에만 잠시 보인다..

머가 문제라서 리프레시가 자동으로 안될까?

갤럭시 S2 에서는 다운로드..

IE 에서도 다운로드

크롬외에는 쓸모가 없나 -ㅁ-?

아니면.. HTTP 스트리밍이 되는.. vlc?
