Method Detail

doClose

protected void doClose()

Implements AbstractCodecExt.doClose().

Specified by:

doClose in class AbstractCodecExt

See Also:

AbstractCodecExt.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 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)

Implements AbstractCodecExt.doProcess(Buffer, Buffer).

Specified by:

doProcess in class AbstractCodecExt

Parameters:

inputBuffer -

outputBuffer -

AbstractCodecExt.doProcess(Buffer, Buffer)
