                                Map<String,String> fmtps)

Constructs a new ParametizedVideoFormat.

Parameters:

encoding - encoding

size - video size

maxDataLength - maximum data length

dataType - data type

frameRate - frame rate

fmtps - format parameters

ParameterizedVideoFormat

public ParameterizedVideoFormat(String encoding,
                                Map<String,String> fmtps)

Initializes a new ParameterizedVideoFormat with a specific encoding and a specific set of format parameters.

Parameters:

encoding - the encoding of the new instance

fmtps - the format parameters of the new instance

ParameterizedVideoFormat

public ParameterizedVideoFormat(String encoding,
                                String... fmtps)

Initializes a new ParameterizedVideoFormat with a specific encoding and a specific set of format parameters.

Parameters:

encoding - the encoding of the new instance

fmtps - the format parameters of the new instance in the form of an array of Strings in which the key and the value of an association are expressed as consecutive elements.

Method Detail

clone

public Object clone()

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

Overrides:

clone in class javax.media.format.VideoFormat

Returns:

a new ParameterizedVideoFormat 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

formatParametersMatch

public boolean formatParametersMatch(javax.media.Format format)

Returns whether or not the format parameters match.

Parameters:

format - format to test

Returns:

true if the format parameters match.

getFormatParameter

public String getFormatParameter(String name)

Returns the format parameters value for the specified name.

Parameters:

name - format parameters name

Returns:

value for the specified format parameters name

getFormatParameters

public Map<String,String> getFormatParameters()

Returns the format parameters Map.

Returns:

the format parameters Map.

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

toMap

public static <T> Map<T,T> toMap(T... entries)

Initializes a new Map from an array in which the key and the value of an association are expressed as consecutive elements.

Type Parameters:

T - the very type of the keys and the values to be associated in the new Map

Parameters:

entries - the associations to be created in the new Map where the key and value of an association are expressed as consecutive elements

Returns:
