       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..

OPTIONS

       -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.
