picture grabber - V4L jpeg capture

    Picture Grabber is a video 4 linux capture application able to read raw data from a V4L compatible device and output to a jpeg file. It works on both V4L1 and V4L2 APIs and it used libjpeg to create the jpeg from the data captured. PictureGrabber aims for a very small footprint (currently binary is about 4k) and only implements the basic features needed to capture data and transform it to a jpeg.

    Picture Grabber can be used with any V4L compatible device (capture cards, webcam, usb v4l devices).
