Thanks to Dmitry Shandyba + (Dmitry.Shandyba@materialise.kiev.ua) for suggesting this. + * Changed a 'htons' call to a 'ntohs' call in ShouldAcceptData + in both the IPv4 and IPv6 transmitters. + * Fixed bug in RTPIPv6Destination. Thanks to Yi-Huan Chan + (yhchan@csie.nctu.edu.tw) and Franco Sinhori + (francosinhori@gmail.com) for bringing this to my attention. + + 3.6.0 (June 2006) + * Added a constructor to the RTCPCompoundPacket class to be able + to parse a compound packet out of a byte array (and not only + out of an RTPRawPacket instance). + * Added a method to RTPSession to send RTCP APP packets. Thanks + to Herman Bastiaens (herman.bastiaens@student.uhasselt.be) + for supplying the patch. + * Fixed Win32 rand_s bug. Thanks to Jeremy Noring + (jnoring@wilife.com) for supplying the patch. + * Removed the GetNumRTPPacketsSent and GetNumRTCPPacketsSent + functions in the transmitter. The counts were only used to + check if packets had been sent. Now, a flag in RTPSession is + used for this purpose. + * Added memory management support. + * Added a member function to RTPSession which allows passing an + RTPTransmitter instance. + * The instances in the destination lists now store struct + sockaddr variables. This makes sending data to each destination + more efficient. + + 3.5.2 (March 2006) + * Fixed bug in the random number functions which are used with + MS Visual Studio 2005. Thanks to Jun Ohasi (jun@jnb.odn.ne.jp) + for bringing the incorrect use of rand_s to my attention. + * Changed types like u_int32_t to types like uint32_t in the + documentation. + + 3.5.1 (March 2006) + * Fixed bug in RTCP scheduler. Due to -= operation on an RTPTime + instance, an incredibly large scheduling interval could be + calculated. + + 3.5.0 (March 2006) + * Now, the define RTP_SNPRINTF is used instead of snprintf, + _snprintf or _snprintf_s. + * In the RTPSources member function MultipleTimeouts, I neglected + to call the OnRemoveSource virtual function. Thanks to Adam Love + (alove@exceptionalinnovation.com) for bringing this to my attention. + * Added a OnSendRTCPCompoundPacket member function to the RTPSession + class. Useful for inspecting outgoing data. + * Modified the templates somewhat. Should cause less compiler problems + this way. Thanks tot Chris Hamilton (chamilton@cs.dal.ca) for + providing this solution. + * On Win32, if possible the functions rand_s and srand_s are now used. + + 3.4.0 (January 2006) + * Changed u_int32_t like types to uint32_t like types. Thanks to + Panagiotis Issaris (takis.issaris@uhasselt.be) for informing me + that these are C99 compliant. + * Changed sprintf functions to safer snprintf functions. Thanks to + Panagiotis Issaris (takis.issaris@uhasselt.be) for pointing this + out. + * Fixed bug in RTPSources (counters were not reset when the source + table was cleared). Thanks to Justin Matthews (jmatthewsr@yahoo.com) + for pointing this out. + * Fixed bug in RTPHashTable and RTPKeyHashTable. Thanks to + Tom Pijsel (tom.pijsel@twelvecubes.com) for bringing this to my + attention. + * Fixed bug in example3.cpp + + 3.3.0 (October 2005) + * Now it is possible to use a user-defined transmission component. + * Added GStreamer transmission component written by Philippe Khalaf + (burger@speedy.org). + + 3.2.1 (September 2005) + * The library wouldn't compile when probation support was disabled. + Thanks to Herman Bastiaens (herman.bastiaens@student.luc.ac.be) for + bringing this to my attention. + * When parsed from an RTPRawPacket, the receive time is also stored + in the RTPPacket instance. + + 3.2.0 (September 2005) + * Modified the routine in the RTPSession class which creates the + CNAME. Aparently on some systems, the 'getlogin' call returns + null. As an alternative, the library uses getenv("LOGNAME"). + Thanks to Mark Schiffmann (schima@neumann-elektronik.com) for + mentioning this to me. + * Added a OnBYEPacket method to the RTPSession class. Thanks to + Sigrid Thijs (sthijs@androme.be) for suggesting this. + * When probation support is enabled, a probation type can be selected + when the session is created. Supported types are "No probation", + "Use probation, but store packets" and "Use probation and discard + packets received in probation mode". Thanks to Chris Flerackers + (cflerackers@androme.be) for suggesting this feature. + * Added a parameter to WaitForIncomingData which indicates if + data is available when the function returns. Based on a suggestion + by Uwe Andersen (uandersen@mayah.com). + * Now using getifaddrs (if possible) to obtain our own IP addresses + (both in IPv4 version and IPv6 version). + * IPv6 code in Win32 version now works, but Visual Studio 2005 beta + has to be used. Thanks to Yi-Huan Chan (yhchan@csie.nctu.edu.tw) + for contributing some code. + * Added Win32 code for GetLocalIPList_Interfaces (both IPv4 and IPv6). + Thanks to Ivan Makushkin (camry@pisem.net) for pointing out how + this could be done. + * Added an option to use a SR packet when sending a BYE message. + Previously, a RR packet was always used, even if a session is + actually an active sender of data. Thanks to Uwe Andersen + (uandersen@mayah.com) for bringing this to my attention. + * Fixed bug in CNAME creation. + * Added WinCE support. Thanks to Maarten Daniels + (maarten.daniels@uhasselt.be) for supplying patches. + * Changed the CurrentTime implementation for the MS-Windows version. + Thanks to Maarten Daniels (maarten.daniels@uhasselt.be) and Chris + Flerackers (cflerackers@androme.be). + + 3.1.0 (October 2004) + * Added a callback OnPollThreadStep which is called at the end of + each loop of the poll thread + * Added the examples subdirectory to the package + * Fixed bug in rtpudpv4transmitter.cpp and rtpudpv6transmitter.cpp + which caused an infinite loop in LeaveAllMulticastGroups. Thanks + to Stijn Agten (stijn.agten@luc.ac.be) for pointing this out. + * Added a function GetTransmissionInfo to the RTPTransmitter class + (and subclasses). The function will return some additional + information about the transmitter, like local IP addresses and + socket descriptors. + + 3.0.2 (September 2004) + * Bugfix in rtpinternalsourcedata.cpp. The bug caused a crash when + duplicate packets were received. Thanks to Dominique Prunier + (dominique.prunier@micromedia-int.com) for informing me about + this. + + 3.0.1 (September 2004) + * Bugfix in rtpudpv4transmitter.cpp and rtpudpv6transmitter.cpp in + method SetReceiveMode + * Removed unused 'acceptownpackets' variable from + rtpudpv4transmitter.cpp and rtpudpv6transmitter.cpp + * Added a 'Dump' function (for debugging) in RTPUDPv4Transmitter + and RTPUDPv6Transmitter + * Now using JThread 1.1.0 + + 3.0.0 (August 2004) + * Complete rewrite of the library to provide better extensibility + and compliance with RFC 3550 + * Changes from the 2.x series: + - The 2.x series was created with the idea that the user + would only need to use the RTPSession class which meant + that the other classes were not very useful by themselves. + This version on the other hand, aims to provide many + useful components to aid the user in building RTP capable + applications. + - In this version, the code which is specific for the + underlying protocol by which RTP packets are transported, + is bundled in a class which inherits its interface from a + class called RTPTransmitter. This makes it easy for + different underlying protocols to be supported. Currently + there is support for UDP over IPv4 and UDP over IPv6. + + 2.9 (July 2004) + * Fixed bug in rtpsrclist.cpp. Thanks to Lukasz Bobowiec + (bobowiec@icslab.agh.edu.pl) + * Added function in RTPSourceData which returns the IP address + * Changed the random routines. Thanks to Jaap Keuter + (jaap.keuter@xs4all.nl) + * Made the shared library link against libstdc++ if possible. + Thanks to Anatoly Yakovenko (aeyakovenko@yahoo.com) for the + suggestion. + + 2.8 (January 2004) + * Added code to avoid a crash when receiving a malformed packet + * Fixed a memory leak (forgot to free memory when a malformed + packet was discarded) + * Changed debug routines for memory tracking + + 2.7b (November 2003) + * Only added --enable-fpic and --enable-fPIC to the configure script + + 2.7 (December 2002) + * Fixed important bug in rtpsources.cpp. This bug could cause + source information to get lost and could create a memory leak. + * Improved support for AIX in multicasting code (uses _AIX define). + Thanks to Klaus Matuschek (klaus.matuschek@infonova.com) + * Fixed possible buffer overrun in rtpcontributingsources.cpp + + 2.6 (January 2002) + * This release only contains some minor changes + * An 'install' target was added to the Makefile + * Some newlines were added add the end of certain files to avoid + compiler warnings + * Improved the jitter calculations somewhat + + 2.5 (December 2000) + * Added the possibility for the user to receive the raw RTCP packets. + * Fixed a bug in RTPContributingSources::CreateLocalCNAME(). In this + routine, the wrong length was passed to 'gethostname'. Thanks to + Sergey V.Shpital (sergey@page.net.ru) for bringing this to my + attention. + * Added a routine to set the Type of Service (ToS) field of the + outgoing packets (both RTP and RTCP). Thank to Philippe Cardon + (philippe.cardon@bt.com) for writing this code. + * Fixed a bug in the 'packets lost' calculation. Thank to Domingo + Cuevas Jr. (dcj@onebox.com) for helping me find this bug. + * Fixed a bug in the sequence number and jitter calculation: when + packets were received out of order, the sequence numbers and + jitter got messed up. Many thanks to Mohammad Tawsheeq Russool + (m.russool@eim.surrey.ac.uk) for helping me track down these + bugs. + * Added the possibility to set the timestamp unit for a particular + source. Previously, it was assumed that their timestamp unit + was the same as that of the local session. + + 2.4 (July 2000) + * Fixed a bug which caused all CSRS's except one to be incorrect. + * Added RTP header extension support (for both sending and receiving). + * Added some things (which should have been there already) to + RTPPacket. + * Adjusted the way in which the login name is retrieved on unix-like + systems. First I used a call to 'getlogin', but apparently this + function messes with timers through the use of 'alarm' calls (at + least on Linux). Now, I use a combination of 'geteuid' and + 'getpwuid' to obtain the necessary information. This does not + have that problem and is a lot cleaner since it doesn't depend + on login info (utmp) like 'getlogin'. Thanks to Roberto Jung Drebes + (drebes@inf.ufrgs.br) for pointing out the timer-problem. + * Made a LaTeX version of the manual and tutorial. Looks a lot nicer. + * Made it possible for the user to specify the local IP address + instead of letting the library figure it out itself. + * Fixed a bug which caused the 'fraction lost' in a RR packet to be + zero all the time. Thanks to Domingo Cuevas Jr. (dcj@onebox.com) for + pointing this out. + * Rewrote the RTCP packet sending routines. Now, they are much cleaner + and much more understandable :) + * Added better support for RTCP 'APP' packets. You can now both send + and receive APP packets. + + 2.3 (April 2000) + * The routine which creates and sends RTCP packets is now a bit faster. + * Added a sample that demonstrates the round-trip time function. + * Added functions to RTPSourceData: now the time when the last RR or + SR report was received can be retrieved. Also, the round trip time + can be retrieved: this is calculated as suggested in RFC 1889. + * Fixed a bug: the LSR value was not calculated correctly, now it is + (or should be ;-) ) + * Instead of specifying defines on the command line, they are now + defined in a config file. The unix version of this file is created + by the configure script. + * Added a member to RTPPacket which I had forgotten (the payload type, + which is obviously important :-) ). + * The library should now be able to work on a VxWorks platform. Thanks + to Dave Osborne (dosborne@argoneng.com) for his help. + * Added a tutorial and a small example application. + * Added some debugging routines (RTPDebug class) to check for memory + leaks. It turned out that there weren't any, so I'm pretty pleased ;) + * I've added a 'configure' script to make compilation a bit easier + across different platforms. Thanks to Qi Han (qh1c4@mizzou.edu) for + helping me to improve the support for the Solaris platform. Also + many thanks to Dario Maggiorini (dario@netdev.usr.dsi.unimi.it) for + helping me test the script on several platforms. + * Added multicasting support. + * A bug in rtpsourcedata.cpp was pointed out and fixed by Ramon Clout + (ramonc@win.tue.nl). Many thanks for this, Ramon. + + 2.2 (February 2000) + * Extra support for Sun and HP. Thanks to Henry Lau (hlau@nuera.com) + and Justin Matthews (jmatthews@nuera.com) for this information. + * The 'Poll' routine in rtpconnection.cpp has been altered. Now, the + routine should work even if there's that ioctl bug (previously, this + bug was only taken into consideration on a Windows platform). + Thanks to Justin Matthews (jmatthews@nuera.com) for his bugreport. + * Added some routines to RTPSession to get the local IP address and the + port number of the sending socket. + * 'install' rule added to the makefile. + * Added the define 'RTP_SOCKLENTYPE_UINT'. See README.TXT for more + information about this. + + 2.1 (December 1999) + * First release of jrtplib. + * Added member functions of RTPSession to retrieve the used sockets. + * Made the destination list faster by using a hash table. + + 2.0 (August 1999) + * First decent implementation of RTP. Entirely rewritten since 1.0. + + 1.0 (August 1999) + * First implementation of RTP. There were a lot of things that weren't + quite right and the organisation of the classes was quite nasty. + However, I learned a lot about RTP making this version, and so it + allowed me to make a good start on version 2.0. diff --git a/Doxyfile b/Doxyfile new file mode 100644 index 0000000..1cecca1 --- /dev/null +++ b/Doxyfile @@ -0,0 +1,1235 @@ +# Doxyfile 1.4.4 + +# This file describes the settings to be used by the documentation system +# doxygen (www.doxygen.org) for a project +# +# All text after a hash (#) is considered a comment and will be ignored +# The format is: +# TAG = value [value, ...] +# For lists items can also be appended using: +# TAG += value [value, ...] +# Values that contain spaces should be placed between quotes (" ") + +#--------------------------------------------------------------------------- +# Project related configuration options +#--------------------------------------------------------------------------- + +# The PROJECT_NAME tag is a single word (or a sequence of words surrounded +# by quotes) that should identify the project. + +PROJECT_NAME = jrtplib + +# The PROJECT_NUMBER tag can be used to enter a project or revision number. +# This could be handy for archiving the generated documentation or +# if some version control system is used. + +PROJECT_NUMBER = 3.7.1 + +# The OUTPUT_DIRECTORY tag is used to specify the (relative or absolute) +# base path where the generated documentation will be put. +# If a relative path is entered, it will be relative to the location +# where doxygen was started.

Most users will probably need just the + * RTPSession class for building an application. This class + * provides the necessary functions for sending RTP data and handles + * the RTCP part internally. + * + * \subsection changes Changes from version 2.x + * + * One of the most important changes is probably the fact that this + * version is based on RFC 3550 and the 2.x versions were based upon + * RFC 1889 which is now obsolete. + * + * Also, the 2.x series was created with the idea that the user would + * only need to use the RTPSession class which meant that the + * other classes were not very useful by themselves. This version on + * the other hand, aims to provide many useful components to aid the + * user in building RTP capable applications. + * + * In this version, the code which is specific for the underlying + * protocol by which RTP packets are transported, is bundled in + * a class which inherits its interface from a class called + * RTPTransmitter. This makes it easy for different underlying + * protocols to be supported. Currently there is support for UDP over + * IPv4 and UDP over IPv6. + * + * For applications such as a mixer or translator using the + * RTPSession class will not be a good solution. Other components can + * be used for this purpose: a transmission component, an SSRC table, + * an RTCP scheduler etc. Using these, it should be much easier to + * build all kinds of applications. + * \section copyright Copyright license + * + * The library code uses the following copyright license: + * + * \code + * Permission is hereby granted, free of charge, to any person + * obtaining a copy of this software and associated documentation files + * (the "Software"), to deal in the Software without restriction, + * including without limitation the rights to use, copy, modify, merge, + * publish, distribute, sublicense, and/or sell copies of the Software, + * and to permit persons to whom the Software is furnished to do so, + * subject to the following conditions: + * + * The above copyright notice and this permission notice shall be + * included in all copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY + * KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE + * WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND + * NONINFRINGEMENT.

First, since this is the + * license of the 2.x series, it only seemed natural that this rewrite + * would contain the same license. Second, since the RTP protocol is + * deliberately incomplete RTP profiles can, for example, define additional + * header fields. The best way to deal with this is to adapt the library + * code itself and that's why I like to keep the license as free as + * possible. + * + * \section starting Getting started with the RTPSession class + * + * To use RTP, you'll have to create an RTPSession object. The constructor + * accepts one parameter, an instance of RTPMemoryManager. By default, no + * memory manager will be used. For now, we'll keep it simple, so this is + * our code so far: + * + * \code + * RTPSession session; + * \endcode + * + * To actually create the session, you'll have to call the Create member + * function which takes three arguments: the first one is of type RTPSessionParams + * and specifies the general options for the session. One parameter of this class + * must be set explicitly, otherwise the session will not be created successfully. + * This parameter is the timestamp unit of the data you intend to send and + * can be calculated by dividing a certain time interval (in seconds) by the + * number of samples in that interval. So, assuming that we'll send 8000 Hz + * voice data, we can use this code: + * + * \code + * RTPSessionParams sessionparams; + * + * sessionparams.SetOwnTimestampUnit(1.0/8000.0); + * \endcode + * + * The other session parameters will probably depend on the actual RTP profile + * you intend to work with. + * + * The second argument of the Create function is a pointer to an RTPTransmissionParams + * instance and describes the parameters for the transmission component. The third + * parameter selects the type of transmission component which will be used. By default, + * an UDP over IPv4 transmitter is used, and for this particular transmitter, the + * transmission parameters should be of type RTPUDPv4TransmissionParams. Assuming + * that we want our RTP portbase to be 8000, we can do the following: + * + * \code + * RTPUDPv4TransmissionParams transparams; + * + * transparams.SetPortbase(8000); + * \endcode + * + * Now, we're ready to call the Create member function of RTPSession. The return + * value is stored in the integer \c status so we can check if something went + * wrong. If this value is negative, it indicates that some error occurred. + * A description of what this error code means can be retrieved by calling + * RTPGetErrorString: + * + * \code + * int status = session.Create(sessionparams,&transparams); + * if (status < 0) + * { + * std::cerr << RTPGetErrorString(status) << std::endl; + * exit(-1); + * } + * \endcode + * + * If the session was created with success, this is probably a good point + * to specify to which destinations RTP and RTCP data should be sent. This is + * done by a call to the RTPSession member function AddDestination. This + * function takes an argument of type RTPAddress. This is an abstract + * class and for the UDP over IPv4 transmitter the actual class to be + * used is RTPIPv4Address. Suppose that we want to send our data to a + * process running on the same host at port 9000, we can do the following: + * + * \code + * uint8_t localip[]={127,0,0,1}; + * RTPIPv4Address addr(localip,9000); + * + * status = session.AddDestination(addr); + * if (status < 0) + * { + * std::cerr << RTPGetErrorString(status) << std::endl; + * exit(-1); + * } + * \endcode + * + * If the library was compiled with JThread support, incoming data is + * processed in the background. If JThread support was not enabled at + * compile time or if you specified in the session parameters that no + * poll thread should be used, you'll have to call the RTPSession + * member function Poll regularly to process incoming data and to send + * RTCP data when necessary. For now, let's assume that we're working + * with the poll thread enabled. + * + * Lets suppose that for a duration of one minute, we want to send + * packets containing 20 ms (or 160 samples) of silence and we want + * to indicate when a packet from someone else has been received. Also + * suppose we have L8 data as defined in RFC 3551 and want to use + * payload type 96. First, we'll set some default values: + * + * \code + * session.SetDefaultPayloadType(96); + * session.SetDefaultMark(false); + * session.SetDefaultTimestampIncrement(160); + * \endcode + * + * Next, we'll create the buffer which contains 160 silence samples + * and create an RTPTime instance which indicates 20 ms or 0.020 seconds. + * We'll also store the current time so we'll know when one minute has + * passed. + * + * \code + * uint8_t silencebuffer[160]; + * + * for (int i = 0 ; i < 160 ; i++) + * silencebuffer[i] = 128; + * + * RTPTime delay(0.020); + * RTPTime starttime = RTPTime::CurrentTime(); + * \endcode + * + * Next, the main loop will be shown. In this loop, a packet containing + * 160 bytes of payload data will be sent. Then, data handling can + * take place but this part is described later in the text. Finally, + * we'll wait 20 ms and check if sixty seconds have passed: + * + * \code + * bool done = false; + * while (!done) + * { + * status = session.SendPacket(silencebuffer,160); + * if (status < 0) + * { + * std::cerr << RTPGetErrorString(status) << std::endl; + * exit(-1); + * } + * + * // + * // Inspect incoming data here + * // + * + * RTPTime::Wait(delay); + * + * RTPTime t = RTPTime::CurrentTime(); + * t -= starttime; + * if (t > RTPTime(60.0)) + * done = true; + * } + * \endcode + * + * Information about participants in the session, packet retrieval + * etc, has to be done between calls to the RTPSession member + * functions BeginDataAccess and EndDataAccess. This ensures that the + * background thread doesn't try to change the same data you're trying + * to access. We'll iterate over the participants using the + * GotoFirstSource and GotoNextSource member functions. Packets from + * the currently selected participant can be retrieved using the + * GetNextPacket member function which returns a pointer to an + * instance of the RTPPacket class. When you don't need the packet + * anymore, it has to be deleted. The processing of incoming data will + * then be as follows: + * + * \code + * session.BeginDataAccess(); + * if (session.GotoFirstSource()) + * { + * do + * { + * RTPPacket *packet; + * while ((packet = session.GetNextPacket()) != 0) + * { + * std::cout << "Got packet with extended sequence number " + * << packet->GetExtendedSequenceNumber() + * << " from SSRC " << packet->GetSSRC() + * << std::endl; + * session.DeletePacket(packet); + * } + * } while (session.GotoNextSource()); + * } + * session.EndDataAccess(); + * \endcode + * + * Information about the currently selected source can be obtained + * by using the GetCurrentSourceInfo member function of the RTPSession class. + * This function returns a pointer to an instance of RTPSourceData which + * contains all information about that source: sender reports from that + * source, receiver reports, SDES info etc. + * + * When the main loop is finished, we'll send a BYE packet to inform other + * participants of our departure and clean up the RTPSession class. Also, + * we want to wait at most 10 seconds for the BYE packet to be sent, + * otherwise we'll just leave the session without sending a BYE packet. + * + * \code + * delay = RTPTime(10.0); + * session.BYEDestroy(delay,"Time's up",9); + * \endcode + * + * The complete code of the program is given in \c example2.cpp. + * + * \section errors Error codes + * + * Unless specified otherwise, functions with a return type \c int + * will return a negative value when an error occurred and zero or a + * positive value upon success. A description of the error code can + * be obtained by using the RTPGetErrorString function, declared + * in rtperrors.h + * + * \section memory Memory management + * + * You can write you own memory manager by deriving a class from RTPMemoryManager. + * The following example shows a very basic implementation. + * + * \code + * class MyMemoryManager : public RTPMemoryManager + * { + * public: + * MyMemoryManager() { } + * ~MyMemoryManager() { } + * + * void *AllocateBuffer(size_t numbytes, int memtype) + * { + * return malloc(numbytes); + * } + * + * void FreeBuffer(void *p) + * { + * free(p); + * } + * }; + * \endcode + * + * In the constructor of RTPSession, you can specify that you would like to use + * this memory manager: + * + * \code + * MyMemoryManager mgr; + * RTPSession session(&mgr); + * \endcode + * + * Now, all memory allocation and deallocation will be done using the AllocateBuffer + * and FreeBuffer implementations of \c mgr. + * + * The second parameter of the RTPMemoryManager::AllocateBuffer member function + * indicates what the purpose is of this memory block. This allows you to handle + * different kinds of data in different ways. + * + * With the introduction of the memory management system, the RTPSession class was + * extended with member function RTPSession::DeletePacket and RTPSession::DeleteTransmissionInfo. + * These functions should be used to deallocate RTPPacket instances and RTPTransmissionInfo + * instances respectively. + * + * \section contact Contact + * + * If you have any questions, remarks or requests about the library or + * if you think you've discovered a bug, you can contact me at + * \c jori(\c dot)\c liesenborgs(\c at)\c gmail(\c dot)\c com + * + * The home page of the library is + * http://research.edm.uhasselt.be/jori/jrtplib/jrtplib.html + * + * There is also a mailing list for the library.
