./net/liblive, Set of C++ libraries for multimedia streaming

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: pkgsrc-2008Q1, Version: 2008.04.09, Package name: liblive-2008.04.09, Maintainer: pkgsrc-users

This package contains a set of C++ libraries for multimedia streaming,
using open standard protocols (RTP/RTCP, RTSP, SIP). These libraries can
be used to build streaming applications. The libraries are already being
used to implement applications such as "liveCaster" and "playRTPMPEG" (for
streaming MP3 audio using RTP/RTCP). The libraries can also be used to
stream, receive, and process MPEG or H.263+ video, and several audio
codecs. They can easily be extended to support additional (audio or video)
codecs, and can also be used to build basic RTSP or SIP clients and
servers, and have been used to add streaming support to existing media
player applications, such as "MPlayer". (For some specific examples of
how these libraries can be used, see the included test programs.)

   Log message:
   Update liblive to 2008.04.09.
   draw upon a patch to update for 2007.01.17 in PR 38038
   While here, add DESTDIR support and fix permission of installed libraries.

   2008.04.09:
   - Corrected a type-related bug in "RTPInterface::handleRead()".  \ 
(Thanks to Brain Lai for noting this.)
   - Fixed a bug in "RTSPClient" that would prevent RTCP \ 
"RR" reports from being sent to
   the correct multicast address when we are receiving a multicast stream. \ 
(Thanks to Changjin Liu for noticing this.)

   2008.04.03:
   - Fixed a bug that was introduced in the "2007.12.27" release.  The \ 
"timeout" parameter to the call to
   "readSocket" in "SocketDescriptor::tcpReadHandler()" in \ 
"RTPInterface.cpp" needed to be initialized
   (to zero) first.  (Thanks to Lodewijk Loos for alerting us to this problem.)
   - Added a new config file "config.bfin-linux-uclibc", and renamed \ 
"config.bfin_uclinux" as "config.bfin-uclinux".
   (Thanks to Mike Frysinger.)

   2008.02.08:
   - Added a hack (suggested by "Romain") to \ 
"MPEG2TransportStreamFramer" to (perhaps)
   produce more accurate per-transport-packet duration estimates for wildly VBR \ 
streams.
   - Updated "MPEG2TransportStreamMultiplexor" to support the addition \ 
of MPEG-4 Audio or Video Elementary Streams.
   - Updated "RTSPOverHTTPServer.cpp" (a work in progress) so that it \ 
complies properly for some versions of
   Visual Studio on Windows.  (Thanks to Eric Flickner for noting this.)

   2008.01.19:
   - Corrected the "getNormalPlayTime()" function - introduced in the \ 
previous release - to allow for 'trick play'
   scale factors other than 1.

   2008.01.18:
   - Added a new member function
     float MediaSubsession::getNormalPlayTime()
   which - given a stream's current presentation time - returns the "Normal \ 
Play Time".
   This function is useful for RTSP streams.
   - Added support for a "a=control:" URL specified in the SDP \ 
description at the session level.

   2008.01.04:
   - Changed the "RTSPClient" timeout - introduced in the previous \ 
release - from
   5s to 30s.
   - Added support for setting and returning the RTSP session start time (as \ 
well as the end time).
   (This eliminates the need for the "live-starttime.patch" file that \ 
VLC was using.)
   - Updated some of the system-specific configuration files, to eliminate the \ 
need for many of the patches that
   the VLC developers added to their code.

   2007.12.27:
   - Added a 5s timeout to the "RTSPClient" code that checks for RTSP \ 
responses.
   This mirrors a change that was already being done to VLC's copy of the code.
   (This is still a short-term fix, until the "RTSPClient" code is \ 
rewritten to
   properly use asynchronous I/O, using the event loop.)
   - Added a timeout to the "readSocket()" call in \ 
"SocketDescriptor::tcpReadHandler()" in "RTPInterface.cpp",
   to handle reading RTP-over-TCP data.  This allows for the possibility of \ 
non-cooperative RTSP clients.
   (Thanks to Peter Leese for this suggestion.)  This is probably not a complete \ 
solution;
   more thought is needed...

   2007.12.07:
   - Fixed "H2633plusVideoFileServerMediaSubsession" to properly use a \ 
dynamic RTP payload type, rather than the
   static type 34 (which is reserved for the now-obsolete old \ 
"video/H263" RTP payload format).

   2007.12.06:
   - Updated "JPEGVideoRTPSource" to take optional 'default width' and \ 
'default height' parameters.
   These parameters can be set by fields in the SDP description, and can be used \ 
to specifiy unusually
   large frame widths and/or heights.  (Thanks to Andrey Filippov.)

   2007.11.18:
   - Fixed a couple of memory leaks in "DarwinInjector".  (Thanks to \ 
Eyal Beit-Halachmi for noting these.)
   - Removed old 'backwards compatibility' stuff from "FramedSource".  \ 
(Noone should be relying upon this any more.)
   - Fixed a bounds-checking error in "parseRTSPRequestString()" \ 
caused by an int vs. unsigned problem.
   (Thanks to Luigi Auriemma for noting this.)
   - In "RTSPClient.cpp", fixed a couple of "unsigned" vs. \ 
"int" nits. (Thanks for Brain Lai for noting this.)

   2007.11.01:
   - Several of the options to "openRTSP" have now been changed, with \ 
two new options added:
   	  -s <initial-seek-time>
   	  -z <scale>
   See the "openRTSP" documentation \ 
<http://www.live555.com/openRTSP/> for details.
   - Fixed a bug in the way that "MPEG4VideoStreamDiscreteFramer" \ 
parses 'config' information (for inclusion in
   the stream's SDP description).  (Thanks to Nicola Bova for helping to \ 
identify this bug.)
   - Eliminated a potential memory (and socket) leak when allocating server \ 
RTP,RTCP socket pairs.
   (Thanks to David Pan for reporting this.)
   - Updated "ByteStreamFileSource" to treat a 0-byte file read the \ 
same as EOF.
   - Ensure that we have reasonable OS buffering for writes on non-blocking sockets.

   2007.08.03a:
   - Removed a debugging printf() that had been left in by mistake.  (Thanks to \ 
Massimo Zito for noticing this.)

   2007.08.03:
   - Updated the "RTSPServer" implementation to work better on systems \ 
with more than one IP address.
   The server will now include - in its RTSP responses - the IP address on which \ 
the corresponding incoming request
   was received.

   2007.07.25:
   - Added some sanity checks to various "MediaSink" subclasses, in \ 
case "fSource" is NULL.
   (Thanks to Andrey Kaminsky for noting one of these.)

   2007.07.10:
   - Made sure that "MPEG2TransportStreamFramer"s estimate of the \ 
average duration of each Transport Packet
   gets updated correctly after each 'seek' operation.  (Thanks to Massimo Zito \ 
for suggesting this.)
   - Fixed a bug in "MPEG2TransportStreamFromESSource" that was \ 
causing presentation
   timestamps to not be generated correctly.  (Thanks to Massimo Zito for \ 
noticing this.)

   2007.07.01:
   - Fixed a bug in "RTSPServer" and "RTSPClient" that would \ 
cause problems when streaming
   files whose names have spaces in them.
   - Fixed a bug in "OnDemandServerMediaSubsession::deleteStream".  \ 
(Thanks to Igor Bukanov.)
   - Make the sockets for "RTPSource", "RTCPInstance" and \ 
"BasicUDPSource" non-blocking, even though they will be read
   from only asynchronously, when packets arrive.  The reason for this is that, \ 
in some OSs, reads on a blocking
   socket can (allegedly) sometimes block, even if the socket was previously \ 
reported (e.g., by "select()") as
   having data available.  (This can supposedly happen if the UDP checksum \ 
fails, for example.)
   (Thanks to Marc Neuberger for pointing this out.)
   - Fixed a bug in "MPEG2TransportFileServerMediaSubsession.cpp" that \ 
was causing 2x
   fast-forward to fail.  (Some debugging code had been left in by mistake.)

   2007.05.24:
   - Modified "setupDatagramSocket()" to better handle setting \ 
"ReceivingInterfaceAddr" when creating a socket
   to be used to send/receive multicast.
   - Made a couple of minor changes to overcome some compilation errors that \ 
some people were apparently seeing.

   2007.05.23:
   - The RTSP server now includes the "source=" parameter in the \ 
response to a RTSP "SETUP" command.
   This works around a bug in QuickTime Player that would cause it to not send \ 
RTCP "RR" packets
   (when playing a unicast stream, and running on Mac OS X).  (Thanks to Dave \ 
Singer et al at Apple for tracking
   down this problem.)
   - The RTSP server implementation no longer terminates the session if it \ 
returns 400 or 405 errors.

   2007.04.24a:
   - Fixed a problem in the new "RTSPOverHTTPServer" code that was \ 
causing some people compilation problems.

   2007.04.24:
   - Fixed a typo in "testOnDemandRTSPServer.cpp".  (Thanks to Nils \ 
Grundback for noticing this.)
   - Modified the signature of \ 
"RTSPServer::specialClientAccessCheck()" (defined in the previous \ 
revision) to add
   a new "clientAddr" parameter (a "struct sockaddr_in"), to \ 
allow special access checking based on clients' IP
   address.
   - Make sure that the locale is set to "POSIX" when calling \ 
"toupper()" or "tolower()" on human-supplied strings.
   (Thanks to Ismail Doenmez for noting this.)

   2007.04.20:
   - Modified "MPEG2TransportStreamMultiplexor" to set the \ 
"discontinuity_indicator" flag for the first
   "adaptation_field" in the output Transport Stream.
   - Changed "AMRAudioRTPSource" to more accurately report \ 
whether/when an interleaved frame's timestamp has
   been synchronized using RTCP.
   (Thanks to David Bertrand for this patch.)
   - Made to a small fix to the previous revision's support for multicast \ 
streaming of raw UDP (nonstandard)
   - Added a virtual function to "OnDemandServerMediaSubsession" for \ 
closing the stream source.
   Subclasses can redefine this, if they wish, to do something smarter. (Thanks \ 
to Igor Bukanov for this patch.)
   - Added support to "RTSPServer" for optionally performing special \ 
per-client access control, beyond the
   standard Digest Authentication method.  (Thanks to Igor Bukanov for this patch.)
   - Made a minor optimization to "Groupsock.cpp".  (Thanks to Maxim \ 
Petrov for this suggestion.)
   - Added an initial implementation of RTSP-over-HTTP at the server level (it \ 
was already supported at the client level).
   (Note: This code has not yet been completed, and doesn yet work, so don't try \ 
to use it.)

   2007.02.20:
   - Updated "RTSPServer" to support multicast streaming of raw UDP \ 
streams (nonstandard).
   (Thanks to Aesmund Grammeltvedt for this modification.)
   - Made "RTSPClient" a little more robust in case the TCP connection \ 
fails.
   - Made "RTPSink::rtpmapLine()" virtual (as requested by Andrew \ 
Voznytsa).
   - Removed an archaic (no longer used) declaration in \ 
"groupsock/include/Groupsock.hh".
   - Added an optional "allowKasennaProtocol" parameter to \ 
"RTSPClient::describeWithPassword()"
   (similar to "RTSPClient::describeURL()").  (Thanks to Igor Bukanov \ 
for this suggestion.)s

   2007.01.17:
      - Fixed a bug that would cause the "MPEG2TransportStreamIndexer" \ 
application to fail when run on a big-endian
   architecture.
   - Added a new cl "H264VideoFileSink", that prepends each incoming \ 
H.264 NAL unit with the prefix 0x000001,
   before writing it to the file.  Also updated the "openRTSP" code to \ 
use this, when receiving H.264/RTP streams.
   (Thanks to Chris Kuiper for contributing this.)
   - Added a temporary #ifdef to "GroupsockHelper.cpp" to work around \ 
a compliation problem when building
   for Cygwin.

   2007.01.11:
   - Improved the "MPEG2IndexFromTransportStream" class to recogize \ 
Transport Stream
   PAT and PMT (tables).  This in turn makes the \ 
"MPEG2TransportStreamIndexer"
   utility more robust.
   - Fixed a minor bug in "MPEG2TransportStreamFromESSource".

   2007.01.09:
   - Added RTSP server support for 'trick play' operations on MPEG-2 Transport Stream
   files.  This requires the presence of a ".tsx" indexle for each \ 
".ts" file.
   (This functionality will shortly be documented on the LIVE555 web site,
   and announced on the "live-devel" mailing list.)
   - Improved the performance of asynchronous file reading in \ 
"ByteStreamFileSource".
   (Thanks to Aesmund Grammeltvedt for this suggestion.)
   - Added "-D_FILE_OFFSET_BITS=64" to the "COMPILE_OPTS" \ 
line for each of the Linux config files, in order to
   alleviate possible problems with I/O on large files.

   2006.12.31:
   - We now implement "ByteStreamFileSource" on Windows using \ 
synchronous file reads,
   by default.  I had thought that Windows XP had fixed the problem - present in
   earlier versions of Windows - whereby open files are not treated as select()able
   sockets.  But apparently the problem is still there.
   - Added code that will - probably in the next release, very soon - support server
   'trick mode' operations on MPEG-2 Transport Stream files.  At present, we have two
   new applications - in the "testProgs" directory - that help support \ 
this:
   "MPEG2TransportStreamIndexer"  create a special index file for a \ 
Transport Stream
   file), and "testMPEG2TransportStreamTrickPlay" (to generate a new \ 
Transport Stream
   file that simulates a 'trick play' operation performed on the original Transport
   Stream file).  See my forthcoming post to the "live-devel" mailing \ 
list for more
   details.
   - Fixed a bug in the Base64 encoding routine.  (Thanks to Sebastian Gracias \ 
for reporting this.)

   2006.12.08:
   - Made sure that each TCP socket used by a "RTSPserver" is \ 
non-blocking, so that a slow or hanging client
   cannot hang a server.  (Thanks to "jers (at) inwind.it" for this \ 
suggestion.)
