라즈베리파이 카메라 비디오 촬영하기

라즈베리파이 카메라 비디오 촬영하기

다음과 같이 입력하면 5초 동안 동영상을 찍는다. 

$ raspivid -o video.h264

터미널에서 omxplayer를 실행시켜 동영상을 확인할 수 있다.

$ omxplayer video.h264

기본 5초를 10초로 찍고 싶으면 t옵션을 이용하면 된다.(단위: 밀리초)

$ raspivid -t 10000 -o video.h264

$ raspivid -?

pi@raspberrypi:~ $ raspivid -?

Display camera output to display, and optionally saves an H264 capture at requested bitrate

usage: raspivid [options]

Image parameter commands

-?, --help : This help information

-w, --width : Set image width <size>. Default 1920

-h, --height : Set image height <size>. Default 1080

-b, --bitrate : Set bitrate. Use bits per second (e.g. 10MBits/s would be -b 10000000)

-o, --output : Output filename <filename> (to write to stdout, use '-o -').

 Connect to a remote IPv4 host (e.g. tcp://192.168.1.2:1234, udp://192.168.1.2:1234)

 To listen on a TCP port (IPv4) and wait for an incoming connection use -l

 (e.g. raspivid -l -o tcp://0.0.0.0:3333 -> bind to all network interfaces, raspivid -l -o tcp://192.168.1.1:3333 -> bind to a certain local IPv4)

-v, --verbose : Output verbose information during run

-t, --timeout : Time (in ms) to capture for. If not specified, set to 5s. Zero to disable

-d, --demo : Run a demo mode (cycle through range of camera options, no capture)

-fps, --framerate : Specify the frames per second to record

-e, --penc : Display preview image *after* encoding (shows compression artifacts)

-g, --intra : Specify the intra refresh period (key frame rate/GoP size). Zero to produce an initial I-frame and then just P-frames.

-pf, --profile : Specify H264 profile to use for encoding

-td, --timed : Cycle between capture and pause. -cycle on,off where on is record time and off is pause time in ms

-s, --signal : Cycle between capture and pause on Signal

-k, --keypress : Cycle between capture and pause on ENTER

-i, --initial : Initial state. Use 'record' or 'pause'. Default 'record'

-qp, --qp : Quantisation parameter. Use approximately 10-40. Default 0 (off)

-ih, --inline : Insert inline headers (SPS, PPS) to stream

-sg, --segment : Segment output file in to multiple files at specified interval <ms>

-wr, --wrap : In segment mode, wrap any numbered filename back to 1 when reach number

-sn, --start : In segment mode, start with specified segment number

-sp, --split : In wait mode, create new output file for each start event

-c, --circular : Run encoded data through circular buffer until triggered then save

-x, --vectors : Output filename <filename> for inline motion vectors

-cs, --camselect : Select camera <number>. Default 0

-set, --settings : Retrieve camera settings and write to stdout

-md, --mode : Force sensor mode. 0=auto. See docs for other modes available

-if, --irefresh : Set intra refresh type

-fl, --flush : Flush buffers in order to decrease latency

-pts, --save-pts : Save Timestamps to file for mkvmerge

-cd, --codec : Specify the codec to use - H264 (default) or MJPEG

-lev, --level : Specify H264 level to use for encoding

-r, --raw : Output filename <filename> for raw video

-rf, --raw-format : Specify output format for raw video. Default is yuv

-l, --listen : Listen on a TCP socket
