 "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 :

 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
