Nearly all of the options available for RaspiVid are available for this application with the exception of demo mode and the preview window. To build, this application expects https://github.com/raspberrypi/userland.git to be cloned to /opt/vc/userland. After that: mkdir build cd build cmake .. make To run (from base dir): ./bin/raspividyuv -o test.yuv Camera Control Options ====================== --sharpness, -sh | Set image sharpness (-100 to 100) Set the sharpness of the image, 0 is the default. --contrast, -co | Set image contrast (-100 to 100) Set the contrast of the image, 0 is the default --brightness, -br | Set image brightness (0 to 100) Set the brightness of the image, 50 is the default. 0 is black, 100 is white. --saturation, -sa | Set image saturation (-100 to 100) set the colour saturation of the image. 0 is the default. --ISO, -ISO | Set capture ISO Not yet implemented --vstab, -vs | Turn on video stabilisation In video mode only, turn on video stabilisation. --ev, -ev | Set EV compensation Set the EV compensation of the image. Range is -10 to +10, default is 0. --exposure, -ex | Set exposure mode Possible options are: off auto Use automatic exposure mode night Select setting for night shooting nightpreview backlight Select setting for back lit subject spotlight sports Select setting for sports (fast shutter etc) snow Select setting optimised for snowy scenery beach Select setting optimised for beach verylong Select setting for long exposures fixedfps Constrain fps to a fixed value antishake Antishake mode fireworks Select settings Note that not all of these settings may be implemented, depending on camera tuning. --awb, -awb | Set Automatic White Balance (AWB) mode Possible options are: off Turn off white balance calculation auto Automatic mode (default) sun Sunny mode cloud Cloudy mode shade Shaded mode tungsten Tungsten lighting mode fluorescent Fluorescent lighting mode incandescent Incandescent lighting mode flash Flash mode horizon Horizon mode Set an effect to be applied to the image --imxfx, -ifx | Set image effect Possible options are: none NO effect (default) negative Negate the image solarise Solarise the image posterize Posterise the image whiteboard Whiteboard effect blackboard Blackboard effect sketch Sketch style effect denoise Denoise the image emboss Emboss the image oilpaint Apply an oil paint style effect hatch Hatch sketch style gpen pastel A pastel style effect watercolour A watercolour style effect film Film grain style effect blur Blur the image saturation Colour saturate the image colourswap Not fully implemented washedout Not fully implemented posterise Not fully implemented colourpoint Not fully implemented colourbalance Not fully implemented cartoon Not fully implemented Colour control --colfx, -cfx | Set colour effect The supplied U and V parameters (range 0 to 255) are applied to the U and Y channels of the image. For example, --colfx 128:128 should result in a monochrome image. --metering, -mm | Set metering mode Specify the metering mode used for the preview and capture average Average the whole frame for metering. spot Spot metering backlit Assume a backlit image matrix Matrix metering Application specific settings ============================= RaspiVid -------- --width, -w | Set image width Width of resulting video. This should be between 64 and 1920. --height, -h | Set image height Height of resulting video. This should be between 64 and 1080. --bitrate, -b | Set bitrate. Use bits per second, so 10MBits/s would be -b 10000000. For H264, 1080p a high quality bitrate would be 15Mbits/s or more. --output, -o | Output filename . Specify the output filename. If not specified, no file is saved --verbose, -v | Output verbose information during run Outputs debugging/information messages during the program run. --timeout, -t | Time before takes picture and shuts down. The program will run for this length of time, then take the capture (if output is specified). If not specified, this is set to 5seconds --framerate, -fps | Specify the frames per second to record At present, the minimum frame rate allowed is 2fps, the maximum is 30fps. This is likely to change in the future. Examples ======== Video Captures -------------- Image size and preview settings are the same as for stills capture. Default size for video recording is 1080p (1920x1080) Record a 5s clip with default settings (1080p30) ./raspividyuv -t 5000 -o video.yuv Record a 5s clip at a specified bitrate (3.5MBits/s) ./raspividyuv -t 5000 -o video.yuv -b 3500000 Record a 5s clip at a specified framerate (5fps) ./raspividyuv -t 5000 -o video.yuv -f 5
