javax.media.format.VideoFormat

org.jitsi.impl.neomedia.codec.video.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.

Constructor Detail

AVFrameFormat

public AVFrameFormat()

Initializes a new AVFrameFormat instance with unspecified size, frame rate and FFmpeg colorspace.

AVFrameFormat

public AVFrameFormat(Dimension size,
                     float frameRate,
                     int pixFmt)

AVFrameFormat

public AVFrameFormat(Dimension size,
                     float frameRate,
                     int pixFmt,
                     int deviceSystemPixFmt)

Initializes a new AVFrameFormat instance with specific size, frame rate and FFmpeg colorspace.

Parameters:

size - the Dimension of the new instance

frameRate - the frame rate of the new instance

pixFmt - the FFmpeg colorspace to be represented by the new instance

deviceSystemPixFmt - the DeviceSystem-specific colorspace to be represented by the new instance

AVFrameFormat

public AVFrameFormat(int pixFmt)

Initializes a new AVFrameFormat instance with a specific FFmpeg colorspace and unspecified size and frame rate.

Parameters:

pixFmt - the FFmpeg colorspace to be represented by the new instance

AVFrameFormat

public AVFrameFormat(int pixFmt,
                     int deviceSystemPixFmt)

Initializes a new AVFrameFormat instance with a specific FFmpeg colorspace and unspecified size and frame rate.

Parameters:

pixFmt - the FFmpeg colorspace to be represented by the new instance

deviceSystemPixFmt - the DeviceSystem-specific colorspace to be represented by the new instance

Method Detail

clone

public Object clone()

Initializes a new AVFrameFormat instance which has the same properties as this instance.

Overrides:

clone in class javax.media.format.VideoFormat

Returns:

a new AVFrameFormat instance which has the same properties as this instance

copy

protected void copy(javax.media.Format f)

Copies the properties of the specified Format into this instance.

Overrides:

copy in class javax.media.format.VideoFormat

Parameters:

f - the Format the properties of which are to be copied into this instance

equals

public boolean equals(Object obj)

Determines whether a specific Object represents a value that is equal to the value represented by this instance.

Overrides:

equals in class javax.media.format.VideoFormat

Parameters:

obj - the Object to be determined whether it represents a value that is equal to the value represented by this instance

Returns:

true if the specified obj represents a value that is equal to the value represented by this instance; otherwise, false

getDeviceSystemPixFmt

public int getDeviceSystemPixFmt()

Gets the DeviceSystem-specific format represented by this instance.

Returns:

the DeviceSystem-specific format represented by this instance

getPixFmt

public int getPixFmt()

Gets the native FFmpeg format represented by this instance.

Returns:

the native FFmpeg format represented by this instance

hashCode

public int hashCode()

Overrides:

hashCode in class Object

intersects

public javax.media.Format intersects(javax.media.Format format)

Finds the attributes shared by two matching Formats. If the specified Format does not match this one, the result is undefined.

Overrides:

intersects in class javax.media.format.VideoFormat

Parameters:

format - the matching Format to intersect with this one

Returns:

a Format with its attributes set to the attributes common to this instance and the specified format

matches

public boolean matches(javax.media.Format format)

Determines whether a specific format matches this instance i.e. whether their attributes match according to the definition of "match" given by Format.matches(Format).

Overrides:

matches in class javax.media.format.VideoFormat

Parameters:

format - the Format to compare to this instance

Returns:

true if the specified format matches this one; otherwise, false

toString

public String toString()

Overrides:

toString in class javax.media.format.VideoFormat
