Constructor Detail

RtcpPacketImpl

public RtcpPacketImpl(TransportPacket parent,
                      Buffer headers,
                      Buffer payload)

Method Detail

write

public void write(OutputStream out,
                  Buffer payload)
           throws IOException

Writes this packet to the OutputStream with the supplied payload. You can use this method to e.g. write a raw UDPPacket to the stream with this payload. Note, if the UDPPacket already had a payload it will be ignored so use this method with care.

Specified by:

write in interface Packet

Throws:

IOException

getNextPacket

public Packet getNextPacket()
                     throws IOException

Get the next frame, or null if there is none. Note, if there isn't another frame but there is still raw data within this frame, it only means that we didn't recognize the payload.

Specified by:

getNextPacket in interface Packet

Returns:

Throws:

IOException

clone

public RtcpPacket clone()

Specified by:

clone in interface Packet

Specified by:

clone in class AbstractPacket

getArrivalTime

public long getArrivalTime()

The arrival time of this packet in microseconds relative to epoch (midnight UTC of January 1, 1970). Note, since this returns with microseconds precision (which may or may not be relevant depending on the hardware on which the packet was captured on) and you wish to format this arrival time into a more human readable format you could use the SimpleDateFormat but it can only handle milliseconds precision (you will have to write your own date formatter if you want microseconds). Here is a snippet illustrating how to turn the arrival time of the packet into a human readable date

 Packet p = ...;
 SimpleDateFormat formatter = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss.SSS");
 Date date = new Date(p.getArrivalTime() / 1000);
 System.out.println("Arrival time: " + formatter.format(date));
 

Note how an integer devision is performed on the arrival time to "cut off" the microseconds from the time stamp

Specified by:

getArrivalTime in interface Packet

Returns:

the arrival time of the packet in microseconds since the start of the epoch
