       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.
