"raspivid" Camera App (commit )
Display camera output to display, and optionally saves an H264 capture at requested bitrate
usage: raspivid [options]
Image parameter commands
-b, --bitrate : Set bitrate. Use bits per second (e.g. 10MBits/s would be -b 10000000)
-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
-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
-stm, --spstimings : Add in h.264 sps timings
-sl, --slices : Horizontal slices per frame. Default 1 (off)
H264 Profile options :
baseline,main,high
H264 Level options :
4,4.1,4.2
H264 Intra refresh options :
cyclic,adaptive,both,cyclicrows
Raw output format options :
yuv,rgb,gray
Raspivid allows output to a remote IPv4 host e.g. -o tcp://192.168.1.2:1234or -o udp://192.168.1.2:1234
To listen on a TCP port (IPv4) and wait for an incoming connection use the -l option
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 port
Common Settings commands
-?, --help : This help information
-w, --width : Set image width <size>
-h, --height : Set image height <size>
-o, --output : Output filename <filename> (to write to stdout, use '-o -'). If not specified, no file is saved
-v, --verbose : Output verbose information during run
-cs, --camselect : Select camera <number>. Default 0
-md, --mode : Force sensor mode. 0=auto. See docs for other modes available
-gps, --gpsdexif : Apply real-time GPS information to output (e.g. EXIF in JPG, annotation in video (requires libgps.so.22)
Preview parameter commands
-p, --preview : Preview window settings <'x,y,w,h'>
-f, --fullscreen : Fullscreen preview mode
-op, --opacity : Preview window opacity (0-255)
-n, --nopreview : Do not display a preview window
-dn, --dispnum : Display on which to display the preview window (dispmanx/tvservice numbering)
