Method Detail

doClose

protected void doClose()

Specified by:

doClose in class AbstractCodec2

doOpen

protected void doOpen()
               throws javax.media.ResourceUnavailableException

Description copied from class: AbstractCodec2

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 inputBuffer,
                        javax.media.Buffer outputBuffer)

Specified by:

doProcess in class AbstractCodec2

getMatchingOutputFormats

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

Get the output formats matching a specific input format.

Overrides:

getMatchingOutputFormats in class AbstractCodec2

Parameters:

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

Returns:

the output formats matching the specified input format

See Also:

AbstractCodec2.getMatchingOutputFormats(Format)

getOutputFormat

public javax.media.Format getOutputFormat()

Get the output format.

Overrides:

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

Returns:

output format

See Also:

AbstractCodec.getOutputFormat()

setExpectedPacketLoss

public void setExpectedPacketLoss(int percentage)

Updates the encoder's packet loss percentage. Takes into account this.alwaysAssumePacketLoss.

Specified by:

setExpectedPacketLoss in interface PacketLossAwareEncoder

Parameters:

percentage - the expected packet loss percentage to set.

getControlComponent

public Component getControlComponent()

Stub. Only added in order to implement the PacketLossAwareEncoder interface.

Specified by:

getControlComponent in interface javax.media.Control

Returns:

null
