Acquiring videos from webcam and converting to PGM

November 11th, 200807:01 pm

ReacTIVision can process image data recorded as PGM files.

First acquire some video from the webcam with mencoder.

mencoder tv:// -tv driver=v4l2:width=640:height=480:device=/dev/video0 -nosound -ovc lavc -o myvideo.avi

This was taken from an article on linux.com. I’ve found that v4l2 works but v4l doesn’t. Replace video0 with your video device.

To convert the avi to a series of PGM files use mplayer.

mplayer -vo pnm:pgm myvideo.avi
