Class AVFrameFormat

  • All Implemented Interfaces:
    Serializable, Cloneable
    public class AVFrameFormat
extends javax.media.format.VideoFormat
    Implements a VideoFormat for a Buffer carrying AVFrame as its data. While the AVFrameFormat class is not strictly necessary and VideoFormat could have be directly used, it is conceived as an appropriate way to avoid possible matching with other VideoFormats and a very obvious one.
