Method Detail

doClose

public void doClose()

Does nothing.

Specified by:

doClose in class AbstractCodecExt

See Also:

AbstractCodecExt.doClose()

doOpen

public 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 AbstractCodecExt

Throws:

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

See Also:

AbstractCodecExt.doOpen()

doProcess

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

Process the input and encodes it.

Specified by:

doProcess in class AbstractCodecExt

Parameters:

inputBuffer - the input data.

outputBuffer - the result data

Returns:

state of the process

See Also:

AbstractCodecExt.doProcess(Buffer, Buffer)

getMatchingOutputFormats

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

Returns the output format that matches the supplied input format.

Overrides:

getMatchingOutputFormats in class AbstractCodecExt

Parameters:

in - input format

Returns:

array of formats that match input ones

See Also:

AbstractCodecExt.getMatchingOutputFormats(Format)
