------------------------------------------------------------------------------ January 19, 2006 JRTPLIB (v3.4.0) Developed at the The Expertise Centre for Digital Media (EDM), a research institute of the Hasselt University http://www.edm.uhasselt.be/ http://www.uhasselt.be/ LIBRARY LOCATION AND CONTACT ============================ Normally, you should be able to download the latest version of the library from this url: http://research.edm.uhasselt.be/jori/jrtplib/jrtplib.html If you have questions about the library, you can mail me at: jori@lumumba.uhasselt.be There is also a mailing list for the library. To subscribe to the list, send an e-mail with the text 'subscribe jrtplib' as the message body (not the subject) to majordomo@edm.uhasselt.be and you'll receive further instructions. ACKNOWLEDGMENT ============== I would like thank the people at the Expertise Centre for Digital Media for giving me the opportunity to create this rewrite of the library.

INSTALLATION NOTES ================== * To compile the library on a unix-like platform, just start the configure script. This should generate a makefile which you can use to start building the library using 'make'. * To compile the library on an MS-Windows platfrom: Visual Studio workspace files are included. The project will search for JThread files in ..\jthread-1.1.2 To compile the library without using JThread, comment the line with RTP_SUPPORT_THREAD in rtpconfig_win.h Note that for Visual Studio 6, you must have service pack 6 for installed to be able to compile the library. * For a manual about the library, please refer to doc/ subdirectory. Using 'make doc', a PDF version of the documentation will be built. Note that you'll need to have the pdflatex LaTeX compiler installed. Alternatively, you can download the documentation from the homepage: http://research.edm.uhasselt.be/jori/jrtplib/jrtplib.pdf * For systems with low memory or for applications which will involve only a few participants at a time: You can set the HASHSIZE defines in rtpsources.h, rtpudpv4transmitter.h and rtpudpv6transmitter.h to a lower value to avoid memory being wasted. Note that the library will have to be recompiled. * Used defines: - WIN32: For compilation on an Win32 platform. - _WIN32_WCE: Define needed for compilation on a WinCE platform - RTP_HAVE_SYS_FILIO: Set if <sys/filio.h> exists. - RTP_HAVE_SYS_SOCKIO: Set if <sys/sockio.h> exists. - RTP_BIG_ENDIAN: If set, assume big-endian byte ordering. - RTP_SOCKLENTYPE_UINT: Indicates that getsockname used an unsigned int as its third parameter. - RTP_HAVE_SOCKADDR_LEN: Indicates that struct sockaddr has an sa_len field. - RTP_SUPPORT_IPV4MULTICAST: Enables support for IPv4 multicasting. - RTP_SUPPORT_THREAD: Enables support for JThread. - RTP_SUPPORT_SDESPRIV: Enables support for RTCP SDES private items. - RTP_SUPPORT_INLINETEMPLATEPARAM: If set, the compiler should be able to handle an inline function as a template parameter. - RTP_SUPPORT_PROBATION: If set, a few consecutive RTP packets are needed to validate a member. - RTP_SUPPORT_GNUDRAND: If set, the RTPRandom class will use drand48_r and srand48_r - RTP_SUPPORT_RANDR: If set and RTP_SUPPORT_GNUDRAND is not set, the RTPRandom class will use rand_r. - RTP_SUPPORT_GETLOGINR: If set, the library will use getlogin_r instead of getlogin. - RTP_SUPPORT_IPV6: If set, IPv6 support is enabled. - RTP_SUPPORT_IPV6MULTICAST: If set, IPv6 multicasting support is enabled. - RTPDEBUG: Enables some memory tracking functions and some debug routines. ------------------------------------------------------------------------------
