Class RawCodec

java.lang.Object

org.monte.media.AbstractCodec

org.monte.media.AbstractVideoCodec

org.monte.media.quicktime.RawCodec

All Implemented Interfaces:

Codec

public class RawCodec
extends AbstractVideoCodec

RawCodec encodes a BufferedImage as a byte[] array.

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 top to bottom and from the left to the right.

Supported input formats:

VideoFormat onlyWith BufferedImage.class, any width, any height, depth=4.

Supported output formats:

VideoFormat onlyWith byte[].class, same width and height as input format, depth=4.
