public class DIBCodec extends AbstractVideoCodec
DIBCodec encodes a BufferedImage as a Microsoft Device Independent
Bitmap (DIB) into a byte array.
The DIB codec only works with the AVI file format. Other file formats, such as QuickTime, use a different encoding for uncompressed video.
This codec currently only supports encoding from a BufferedImage into
the file format. Decoding support may be added in the future.
This codec does not encode the color palette of an image. This must be done separately.
The pixels of a frame are written row by row from bottom to top and from the left to the right. 24-bit pixels are encoded as BGR.
Supported input formats:
Format with BufferedImage.class, any width, any height,
depth=4.
Format with byte[].class, same width and height as input
format, depth=4.
