Method Detail

doClose

protected void doClose()

Specified by:

doClose in class AbstractCodecExt

doOpen

protected void doOpen()
               throws javax.media.ResourceUnavailableException

Description copied from class: AbstractCodecExt

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

doProcess

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

Specified by:

doProcess in class AbstractCodecExt

getMatchingOutputFormats

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

Get the output formats matching a specific input format.

Overrides:

getMatchingOutputFormats in class AbstractCodecExt

Parameters:

inputFormat - the input format to get the matching output formats of

Returns:

the output formats matching the specified input format

See Also:

AbstractCodecExt.getMatchingOutputFormats(Format)

getMatchingOutputFormats

static javax.media.Format[] getMatchingOutputFormats(javax.media.Format inputFormat,
                                                     javax.media.Format[] supportedInputFormats,
                                                     javax.media.Format[] supportedOutputFormats)

getOutputFormat

public javax.media.Format getOutputFormat()

Get the output format.

Overrides:

getOutputFormat in class net.sf.fmj.media.AbstractCodec

Returns:

output format

AbstractCodec.getOutputFormat()
