Constructor Detail

DefaultRtpStream

public DefaultRtpStream(PcapGlobalHeader globalHeader,
                        long ssrc)

Method Detail

onPacket

public void onPacket(RtpPacket msg)

getPackets

public List<RtpPacket> getPackets()

Get all Packets that belongs to this stream.

Specified by:

getPackets in interface Stream<RtpPacket>

Returns:

getDuration

public long getDuration()

Get the duration in microseconds of the stream. Note, see comment on Packet.getArrivalTime() regarding the microsecond precision. Depending on the underlying protocol this can be as simple as the time between the first to the last packet, which is what the RtpStream does. Or, it can be more complicated as with a SipStream that checks the duration of the dialog (if one was established).

Specified by:

getDuration in interface Stream<RtpPacket>

Returns:

the duration (in milliseconds) of this Stream. If the duration cannot be calulated for whatever reason (no packets at all? Only one packet?), then -1 (negative one) will be returned.

getTimeOfFirstPacket

public long getTimeOfFirstPacket()

Get the arrival time of the very first packet in this stream. Note, see comment on Packet.getArrivalTime() regarding the microsecond precision.

Specified by:

getTimeOfFirstPacket in interface Stream<RtpPacket>

Returns:

the arrival time of the first packet (in microseconds), -1 (negative one) in case this Stream doesn't contain any packets.

getTimeOfLastPacket

public long getTimeOfLastPacket()

Get the arrival time of the last packet in this stream. Note, see comment on Packet.getArrivalTime() regarding the microsecond precision.

Specified by:

getTimeOfLastPacket in interface Stream<RtpPacket>

Returns:

the arrival time of the last packet (in microseconds), -1 (negative one) in case this Stream doesn't contain any packets.

getStreamIdentifier

public StreamId getStreamIdentifier()

Get the unique StreamId for this particular Stream.

Specified by:

getStreamIdentifier in interface Stream<RtpPacket>

Returns:

write

public void write(OutputStream out)
           throws IOException

Write this Stream to the specified OutputStream. Also see Pcap.createOutputStream(OutputStream).

Specified by:

write in interface Stream<RtpPacket>

Parameters:

out - the OutputStream, which typically is a PcapOutputStream.

Throws:

IOException

getMaxJitter

public long getMaxJitter()

Specified by:

getMaxJitter in interface RtpStream

getMeanJitter

public long getMeanJitter()

Specified by:

getMeanJitter in interface RtpStream

getMaxDelta

public long getMaxDelta()

Specified by:

getMaxDelta in interface RtpStream

getLostPackets

public long getLostPackets()

Specified by:

getLostPackets in interface RtpStream

getSequenceErrors

public long getSequenceErrors()

Specified by:

getSequenceErrors in interface RtpStream
