Constructor Detail

RTCPSenderInfo

public RTCPSenderInfo(byte[] rtcpPacket,
                      int offset,
                      int length)
               throws java.io.IOException

Parses an RTCP Sender Report (SR) packet

Parameters:

offset - offset after which the RTCP SR starts

length - length of the packet

rtcpPacket - The data of the RTCP packet

Throws:

java.io.IOException - I/O Exception

Method Detail

toString

public java.lang.String toString()

Returns a String reprensenting the information about the RTCP sender

Overrides:

toString in class java.lang.Object

getTimestamp

public long getTimestamp()

Returns the timestamp of the information

Returns:

timestamp of this information

getNtpTimestampSecs

public double getNtpTimestampSecs()

Returns the timestamp value in seconds

Returns:

timestamp in seconds

getNtpTimestampMSW

public long getNtpTimestampMSW()

Returns the timestamp most significant word

Returns:

the timestamp's most significant word

getNtpTimestampLSW

public long getNtpTimestampLSW()

Returns the timestamp least significant word

Returns:

the timestamp's least significant word

getRtpTimestamp

public long getRtpTimestamp()

Returns the RTP timestamp of this SR packet

Returns:

the timestamp of this RTCP packet

getOctetCount

public long getOctetCount()

Returns the octet (cumulative) count. The total number of payload octets (i.e., not including header or padding) transmitted in RTP data packets by the sender since starting transmission up until the time this SR packet was generated. This field can be used to estimate the average payload data rate.

Returns:

the number of bytes sent until now

getPacketCount

public long getPacketCount()

Returns the packet (cumulative) count. The total number of RTP data packets transmitted by the sender since starting transmission up until the time this SR packet was generated.

Returns:

the number of packets sent until now
