Constructor Detail

DePacketizer

public DePacketizer()

Initializes a new DePacketizer instance.

Method Detail

doClose

protected void doClose()

Specified by:

doClose in class AbstractCodec2

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

doProcess

protected int doProcess(javax.media.Buffer inBuf,
                        javax.media.Buffer outBuf)

Specified by:

doProcess in class AbstractCodec2
