JRTPLIB was developed at the School for Knowledge Technology (or ‘School voor Kennistechnologie’ in Dutch), a cooperation between the Hasselt University and the Maastricht University.
The library offers support for the Real-time Transport Protocol (RTP), defined in RFC 3550.
JRTPLIB makes it very easy to send and receive RTP packets and the RTCP (RTP Control Protocol) functions are handled entirely internally. For more detailed information you should take a look at the documentation included in the package.
Currently, the library is known to work on the following platforms:
· MS-Windows (both Win32 and WinCE)
The library will probably work on other unix-like environments too.

RTP is a protocol for real-time communication between end-points.
It offers bidirectional flow control, and packetization and
de-packetization. It operates on top of UDP, and is intended as a
The JRTPLIB Activation Code library supports both RTP and RTCP. Both are highly
integrated with the library, and are used. The library provides an
RTP-packet server, which means it makes it easy to send RTP
packets. It also offers an RTCP-packet server, which means it makes
it easy to receive RTP packets and RTCP packets. There is a
RTP/RTCP client which is simple to implement.
RTP/RTCP Packet Format:
RTP packet format consists of one RTP header plus an optional
payload. RTP packets are 7-octet aligned.
RTP header consists of an 8-bit version number, which is set to
‘1’ by the sender, and indicates the maximum RTP packet version
which the receiver can handle.
A 32-bit PSID is defined for future extensions.
A 16-bit SSRC is defined. This is set to zero by the sender and is
always ignored by the receiver.
A 32-bit Packet offset value is included in RTP packets. This is
set to zero by the sender and is always ignored by the receiver.
A 16-bit Sender timestamp value is also included in RTP packets.
This is set to zero by the sender and always ignored by the
The timestamp of the first RTCP packet seen by the sender is also
included in RTP/RTCP packets. This is ignored by the receiver.
RTP/RTCP header size is 10-octets.
The following is an example RTP/RTCP packet, sent from a RTP/RTCP
client to a RTP/RTCP server. The timestamp has been suppressed to
make the example more readable.
:tp_type RTP/AVP 00000
:ptype RTP/AVP 00000
Packet offset: 0
JRTPLIB 1.78 (April-2022)
JRTPLIB was designed to get a lot of things straight. Also, the library is relatively small, so that it should fit anywhere.
· RTP: RTP packet handling
· RTCP: RTP Control Protocol handling
· SIP: SIP handling
· SRTP: Security over RTP handling
· UDP/IP: UDP (RTP) and IP (RTP) routing
· JNI: Native call to Java routines
· JNI-Bridge: Call Java from non-Java code
· Sender/Receiver: Main example
· Multicast: Multicast handling

JRTPLIB 1.78 Activator [32|64bit]
JRTPLIB includes all the necessary classes to write a RTP-application. The library offers an API that is as close to the POSIX standard as possible and makes it possible to use the library on a broad range of OS’s. You should not need to install anything extra to use it.
JRTPLIB consists of five main modules. These modules are:
· RTSP Protocol
· Main Unit
In order to create a new RTP-app that uses the RTP-module, you write:
(where 192.168.0.12 is the IP-Address of the host to which the RTP-app will be sending packets)
In this example we are not using RTCP at the moment. If we wanted to use RTCP, we would write:
rtpRTP.createRTP(“192.168.0.12”, 1900, false, true);
If you want to use RTSP, you must read the RTSP chapter. But, before you go further, you should read the RTSP chapter as well.
When you have created a RTP-app, you can send it a datastream. This is done by calling “sendDatastream()” or by using “addDatastream()” (this is the most common use of the method).
In the above example, we are assuming that the RTCP-app has been given a 32-bit sdp-description (which has been saved in rtpRTCP) to which it should send reports.
In the above example we are assuming that the RTCP-app has been given a 34-bit sdp-description (which has been saved in rtpRTCP) to which it should send reports.
What’s New In JRTPLIB?
JRTPLIB includes support for RTP and RTCP.
The library is intended to be used by clients and servers.
RTP includes support for RTP-unicast, RTP-multicast and RTP-broadcast.
RTCP includes support for RTCP-unicast and RTCP-multicast.
Three main functions are provided to send and receive RTP and RTCP packets:
The sendRtpPacket() function sends an RTP packet on the socket, when the RTP headers are fully built.
The recvRtpPacket() function reads the RTP payload from the socket, once it is fully sent. The received RTP payload is put into the RtpPacket structure.
The recvRtcpPacket() function works the same as recvRtpPacket(), except for the RTCP payload.
The sendRtcpPacket() function sends an RTCP packet on the socket, when the RTCP headers are fully built.
The setOption() function sets the option as described in the header. For instance, if’sendOption’ is set to’sendpayload’, then the function will first send the RTP payload, then send the RTCP payload.
Both the’sendOption’ and’recvOption’ are set to’sendpayload’.
The setOption() function sets the’recvOption’ to’sendpayload’.
The receive() function has two modes:
1. If ‘enableOptionRecv’ is set to ‘true’, the library will try to receive options (RTP and RTCP) when the payload is received. The options will first be put into the RtcpOption structure, then the RtpOption structure.
2. If ‘enableOptionRecv’ is set to ‘false’, the library will not try to receive options.
This is because the RTP payloads are usually much bigger than the RTCP payloads. If the library has received the RTP payload, then it will put the RTCP payload into the RtcpOption structure.
The options are set by passing the structure as parameter to setOption(). For instance, if ‘option->length’ is set to 10 and ‘option->offset’ is set
