Constructor Detail

ControlTransformInputStream

public ControlTransformInputStream(DatagramSocket socket)

Initializes a new ControlTransformInputStream which is to receive packet data from a specific UDP socket.

Parameters:

socket - the UDP socket the new instance is to receive data from

Method Detail

addRTCPFeedbackListener

public void addRTCPFeedbackListener(RTCPFeedbackListener listener)

Adds an RTCPFeedbackListener.

Parameters:

listener - the RTCPFeedbackListener to add

removeRTCPFeedbackListener

public void removeRTCPFeedbackListener(RTCPFeedbackListener listener)

Removes an RTCPFeedbackListener.

Parameters:

listener - the RTCPFeedbackListener to remove

read

public int read(byte[] inBuffer,
                int offset,
                int length)
         throws IOException

Copies the content of the most recently received packet into inBuffer.

Specified by:

read in interface javax.media.protocol.PushSourceStream

Overrides:

read in class RTPConnectorInputStream

Parameters:

inBuffer - the byte[] that we'd like to copy the content of the packet to.

offset - the position where we are supposed to start writing in inBuffer.

length - the number of bytes available for writing in inBuffer.

Returns:

the number of bytes read

Throws:

IOException - if length is less than the size of the packet.
