Class AVIOutputStreamOLD

java.lang.Object
  org.monte.media.avi.AVIOutputStreamOLD

Deprecated. Use AVIWriter instead of this class.

public class AVIOutputStreamOLD
extends java.lang.Object

This class supports writing of images into an AVI 1.0 video file.

The images are written as video frames.

Video frames can be encoded with one of the following formats:

• JPEG
• PNG
• RAW
• RLE

All frames must have the same format. When JPG is used each frame can have an individual encoding quality.

All frames in an AVI file must have the same duration. The duration can be set by setting an appropriate pair of values using methods setFrameRate(int) and setTimeScale(int).

The length of an AVI 1.0 file is limited to 1 GB. This class supports lengths of up to 4 GB, but such files may not work on all players.

Constructor Detail

AVIOutputStreamOLD

public AVIOutputStreamOLD(java.io.File file,
                          AVIOutputStreamOLD.AVIVideoFormat format)
                   throws java.io.IOException

Deprecated.

Creates a new AVI file with the specified video format and frame rate. The video has 24 bits per pixel.

Parameters:

file - the output file

format - Specifies the video format.

Throws:

java.lang.IllegalArgumentException - if videoFormat is null or if frame rate is <= 0

java.io.IOException

AVIOutputStreamOLD

public AVIOutputStreamOLD(java.io.File file,
                          AVIOutputStreamOLD.AVIVideoFormat format,
                          int bitsPerPixel)
                   throws java.io.IOException

Deprecated.

Creates a new AVI file with the specified video format and frame rate.

Parameters:

file - the output file

format - Selects an encoder for the video format.

bitsPerPixel - the number of bits per pixel.

Throws:

java.lang.IllegalArgumentException - if videoFormat is null or if frame rate is <= 0

java.io.IOException

AVIOutputStreamOLD

public AVIOutputStreamOLD(javax.imageio.stream.ImageOutputStream out,
                          AVIOutputStreamOLD.AVIVideoFormat format)
                   throws java.io.IOException

Deprecated.

Creates a new AVI output stream with the specified video format and framerate.

Parameters:

out - the underlying output stream

format - Selects an encoder for the video format.

Throws:

java.lang.IllegalArgumentException - if videoFormat is null or if framerate is <= 0

java.io.IOException

Method Detail

setTimeScale

public void setTimeScale(int newValue)

Deprecated.

Used with frameRate to specify the time scale that this stream will use. Dividing frameRate by timeScale gives the number of samples per second. For video streams, this is the frame rate. For audio streams, this rate corresponds to the time needed to play nBlockAlign bytes of audio, which for PCM audio is the just the sample rate.

The default value is 1.

Parameters:

newValue -

getTimeScale

public int getTimeScale()

Deprecated.

Returns the time scale of this media.

Returns:

time scale

setFrameRate

public void setFrameRate(int newValue)

Deprecated.

Sets the rate of video frames in time scale units.

The default value is 30. Together with the default value 1 of timeScale this results in 30 frames pers second.

Parameters:

newValue -

getFrameRate

public int getFrameRate()

Deprecated.

Returns the frame rate of this media.

Returns:

frame rate

setPalette

public void setPalette(java.awt.image.IndexColorModel palette)

Deprecated.

Sets the global color palette.

setVideoCompressionQuality

public void setVideoCompressionQuality(float newValue)

Deprecated.

Sets the compression quality of the video track. A value of 0 stands for "high compression is important" a value of 1 for "high image quality is important".

Changing this value affects frames which are subsequently written to the AVIOutputStreamOLD. Frames which have already been written are not changed.

This value has only effect on videos encoded with JPG format.

The default value is 0.9.

Parameters:

newValue -

getVideoCompressionQuality

public float getVideoCompressionQuality()

Deprecated.

Returns the video compression quality.

Returns:

video compression quality

setVideoDimension

public void setVideoDimension(int width,
                              int height)

Deprecated.

Sets the dimension of the video track.

You need to explicitly set the dimension, if you add all frames from files or input streams.

If you add frames from buffered images, then AVIOutputStreamOLD can determine the video dimension from the image width and height.

Parameters:

width - Must be greater than 0.

height - Must be greater than 0.

getVideoDimension

public java.awt.Dimension getVideoDimension()

Deprecated.

Gets the dimension of the video track.

Returns null if the dimension is not known.

writeFrame

public void writeFrame(java.awt.image.BufferedImage image)
                throws java.io.IOException

Deprecated.

Writes a frame to the video track.

If the dimension of the video track has not been specified yet, it is derived from the first buffered image added to the AVIOutputStreamOLD.

Parameters:

image - The frame image.

Throws:

java.lang.IllegalArgumentException - if the duration is less than 1, or if the dimension of the frame does not match the dimension of the video track.

java.io.IOException - if writing the image failed.

writeFrame

public void writeFrame(java.io.File file)
                throws java.io.IOException

Deprecated.

Writes a frame from a file to the video track.

This method does not inspect the contents of the file. For example, Its your responsibility to only add JPG files if you have chosen the JPEG video format.

If you add all frames from files or from input streams, then you have to explicitly set the dimension of the video track before you call finish() or close().

Parameters:

file - The file which holds the image data.

Throws:

java.lang.IllegalStateException - if the duration is less than 1.

java.io.IOException - if writing the image failed.

writeFrame

public void writeFrame(java.io.InputStream in)
                throws java.io.IOException

Deprecated.

Writes a frame to the video track.

This method does not inspect the contents of the file. For example, its your responsibility to only add JPG files if you have chosen the JPEG video format.

If you add all frames from files or from input streams, then you have to explicitly set the dimension of the video track before you call finish() or close().

Parameters:

in - The input stream which holds the image data.

Throws:

java.lang.IllegalArgumentException - if the duration is less than 1.

java.io.IOException - if writing the image failed.

close

public void close()
           throws java.io.IOException

Deprecated.

Closes the movie file as well as the stream being filtered.

Throws:

java.io.IOException - if an I/O error has occurred

finish

public void finish()
            throws java.io.IOException

Deprecated.

Finishes writing the contents of the AVI output stream without closing the underlying stream. Use this method when applying multiple filters in succession to the same output stream.

Throws:

java.lang.IllegalStateException - if the dimension of the video track has not been specified or determined yet.

java.io.IOException - if an I/O exception has occurred
