This application is intended to output a raw YUV video stream. 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
--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

Colour control
--colfx, -cfx | Set colour effect <U:V>
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
--width, -w | Set image width <size>
Width of resulting video. This should be between 64 and 1920.
--height, -h | Set image height <size>
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 <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.
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
