Class RawCodec

java.lang.Object

org.monte.media.av.AbstractCodec

org.monte.media.av.codec.video.AbstractVideoCodec

org.monte.media.quicktime.codec.video.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.

Method Details

setOutputFormat

public Format setOutputFormat(Format f)

Description copied from interface: Codec

Sets the output format. Returns the format that was actually set. This is the closest format that the Codec supports. Returns null if the specified format is not supported and no reasonable match could be found.

Specified by:

setOutputFormat in interface Codec

Overrides:

setOutputFormat in class AbstractCodec

writeKey8

public void writeKey8(OutputStream out,
 byte[] data,
 int width,
 int height,
 int offset,
 int scanlineStride)
               throws IOException

Encodes an 8-bit key frame.

Parameters:

out - The output stream.

data - The image data.

width - The width of the image in data elements.

height - The height of the image in data elements.

offset - The offset to the first pixel in the data array.

scanlineStride - The number to append to offset to get to the next scanline.

Throws:

IOException

writeKey16

public void writeKey16(OutputStream out,
 short[] data,
 int width,
 int height,
 int offset,
 int scanlineStride)
                throws IOException

Encodes a 24-bit key frame.

Parameters:

out - The output stream.

data - The image data.

width - The width of the image in data elements.

height - The height of the image in data elements.

offset - The offset to the first pixel in the data array.

scanlineStride - The number to append to offset to get to the next scanline.

Throws:

IOException

writeKey24

public void writeKey24(OutputStream out,
 int[] data,
 int width,
 int height,
 int offset,
 int scanlineStride)
                throws IOException

Encodes a 24-bit key frame.

Parameters:

out - The output stream.

data - The image data.

width - The width of the image in data elements.

height - The height of the image in data elements.

offset - The offset to the first pixel in the data array.

scanlineStride - The number to append to offset to get to the next scanline.

Throws:

IOException

writeKey32

public void writeKey32(OutputStream out,
 int[] data,
 int width,
 int height,
 int offset,
 int scanlineStride)
                throws IOException

Encodes a 24-bit key frame.

Parameters:

out - The output stream.

data - The image data.

width - The width of the image in data elements.

height - The height of the image in data elements.

offset - The offset to the first pixel in the data array.

scanlineStride - The number to append to offset to get to the next scanline.

Throws:

IOException

writeKey24

public void writeKey24(OutputStream out,
 BufferedImage image)
                throws IOException

Encodes a 24-bit key frame.

Parameters:

out - The output stream.

image - The image.

Throws:

IOException

process

public int process(Buffer in,
 Buffer out)

Description copied from interface: Codec

Performs the media processing defined by this codec.

Copies the data from the input buffer into the output buffer.

Returns:

A combination of processing flags.
