vidcat - capture a frame from a video4linux device
vidcat [-h?blgV] [-d <device>] [-f jpeg|ppm|png] [-i tv|comp1|com1|s-video] [-n pal|ntsc|secam] [-q <1..100>] [-s WIDTHxHEIGHT] [-o <file>]
vidcat captures a frame from a video4linux device and writes the result to the standard output device. With the following options you can define output format, size etc..
-d device Use an alternate v4l device, '/dev/video' is the default device. -b This applies only to PPM output. With this option the PPM ouput is written in binary mode. -f ppm|jpeg|png|yuv4mpeg Define the file format to use for the output stream. The default is "jpeg". -g Use greyscale instead of RGB24 for the output data. -i tv|comp1|comp2|s-video Set the input channel to use. The default value is none, which means the preset of the device is used. -l Loops until CTRL+C is pressed. This is the default for the YUV4MPEG output. -n pal|ntsc|secam Select the input norm for the grabbing device. The default value is none. -o file Use the named file for output instead of standard out. -p c|g|y|Y Set the palette to use: c = RGB24, g=GREY, y=YUV420P, Y=YUV422P. -q 1..100 Set the quality for JPEG output. The value could be a number between 1 and 100. The default value is 80. -s WIDTHxHEIGHT Define the size of the output frame in pixels. The default setting is 320x240. -V Show version number and exit.
