Constructor Detail

JNIDecoder

public JNIDecoder()

Initializes a new JNIDecoder instance.

Method Detail

doClose

protected void doClose()

Specified by:

doClose in class AbstractCodec2

See Also:

AbstractCodec2.doClose()

doOpen

protected void doOpen()
               throws javax.media.ResourceUnavailableException

Opens this Codec and acquires the resources that it needs to operate. A call to PlugIn.open() on this instance will result in a call to doOpen only if AbstractCodec.opened is false. All required input and/or output formats are assumed to have been set on this Codec before doOpen is called.

Specified by:

doOpen in class AbstractCodec2

Throws:

javax.media.ResourceUnavailableException - if any of the resources that this Codec needs to operate cannot be acquired

See Also:

AbstractCodec2.doOpen()

doProcess

protected int doProcess(javax.media.Buffer inputBuffer,
                        javax.media.Buffer outputBuffer)

Decodes Speex media from a specific input Buffer

Specified by:

doProcess in class AbstractCodec2

Parameters:

inputBuffer - input Buffer

outputBuffer - output Buffer

Returns:

BUFFER_PROCESSED_OK if inBuffer has been successfully processed

See Also:

AbstractCodec2.doProcess(Buffer, Buffer)

getMatchingOutputFormats

protected javax.media.Format[] getMatchingOutputFormats(javax.media.Format inputFormat)

Get all supported output Formats.

Overrides:

getMatchingOutputFormats in class AbstractCodec2

Parameters:

inputFormat - input Format to determine corresponding output Formats

Returns:

array of supported Format

See Also:

AbstractCodec2.getMatchingOutputFormats(Format)

setInputFormat

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

Sets the Format of the media data to be input for processing in this Codec.

Specified by:

setInputFormat in interface javax.media.Codec

Overrides:

setInputFormat in class AbstractCodec2

Parameters:

format - the Format of the media data to be input for processing in this Codec

Returns:

the Format of the media data to be input for processing in this Codec if format is compatible with this Codec; otherwise, null

See Also:

AbstractCodec2.setInputFormat(Format)
