Class AWTFrameGrab

java.lang.Object

org.jcodec.api.FrameGrab

org.jcodec.api.awt.AWTFrameGrab

public class AWTFrameGrab
extends org.jcodec.api.FrameGrab

This class is part of JCodec ( www.jcodec.org ) This software is distributed under FreeBSD License Extracts frames from a movie into uncompressed images suitable for processing. Supports going to random points inside of a movie ( seeking ) by frame number of by second. NOTE: Supports only AVC ( H.264 ) in MP4 ( ISO BMF, QuickTime ) at this point. NOTE: AWT specific routines
