- Update to version 1.4.2
New Features and Enhancements
* Added support for C++11. Reworked timing and
synchronization objects. Three sources of timing are now
available (selected via a build option):
+ POSIX gettimeofday() - default build mode (affected by
discontinuous jumps in the system time);
+ POSIX CLOCK_MONOTONIC. CMake build option:
-DENABLE_MONOTONIC_CLOCK=ON. See --enable-monotonic-clock
in BuildOptions.md;
+ C++11 std::chrono::steady_clock, std::thread,
std::mutex, etc. CMake build option:
-DENABLE_STDCXX_SYNC=ON. See --enable-stdcxx-sync in
BuildOptions.md.
* Added SRT Source Time API support. It allows setting a
source timestamp on a packet that corresponds to a packet
creation/reception time. See the Time Access section of
the API docs.
* Added an improved retransmission algorithm which reduces
the retransmission overhead on a link. Set option
SRTO_RETRANSMITALGO=1.
* Added SRTO_BINDTODEVICE option to bind a socket to a
specified NIC. SRTO_BINDTODEVICE option reflects the
system option SO_BINDTODEVICE for an SRT socket.
* Customizable rejection reason code. SRT library now lets
the application provide a code with rejection reason (in a
listener callback) if connection request has been rejected
by the application. See Rejection Codes in the Access
Control guide.
* Added new rejection reason: on timeout. See
SRT_REJ_TIMEOUT in API-functions.md.
* Extended SRT statistics with pktSentUniqueTotal,
pktRecvUniqueTotal. Statistics documentation now has a
summary table for better navigation.
* Added srt_getversion() API function.
* Moved socket options documentation to a separate file
APISocketOptions.md. It now has a summary table for better
navigation.
* Socket options SRTO_INPUTBW and SRTO_OHEADBW are now
readable.
* The logging functionality has been improved by means of
defining new and more fine-grained Functional Areas (FA)
to which log messages are assigned. This is done to prevent
too many debug log messages from the library influencing
performance with the debug logging turned on.
Fixed Issues
* Fixed bug: finding the listener's muxer only by port
number was wrong.
* Fixed wrong reject reason on async connect.
* Fixed CSndLossList::insert with negative offset.
* Fixed default binding for IPv6-target rendezvous.
* Fixed HS TSBPD flags check.
* Improved CRcvLossList protection from concurrent access.
* Fixed error reporting on connect/accept.
* Correctly handle IPv4 connections on IPv6 listener.
* Fixed Moving Average for receiver and sender buffers.
* Protecting RCV buffer access.
* Fixed local storage depleted issue #486.
* Fixed restrictions on pre-bind only options.
* Avoid reporting packets rebuilt by FEC as lost.
* Improved inserting a serial element into sender's loss
list.
* Fixed handling of stale loss report.
* Fixed closing the crypto control.
* Added CSync class as a high-level CV wrapper.
* Renamed legacy UDT_EPOLL_* symbols.
* Eliminated ref_t. Some more convention fixes.
* Crypto: Reset the passphrase in memory on close for
security reasons.
Deprecated or Renamed
* Removed deprecated socket options: SRTO_TWOWAYDATA,
SRTO_TSBPDMAXLAG, SRTO_CC, SRTO_MAXMSG, SRTO_MSGTTL,
SRTO_SNDPBKEYLEN, SRTO_RCVPBKEYLEN.
* Removed deprecated option names: SRTO_SMOOTHER (use
SRTO_CONGESTION), SRTO_STRICTENC (use
SRTO_ENFORCEDENCRYPTION).
version 1.4.1:
Improvements
* Improved periodic NAK report timing
* Use monotonic clock in CTimer::sleepto()
* Initial reorder tolerance set to maximum value
(SRTO_LOSSMAXTTL)
* Added pktReorderTolerance to stats
* Use busy wait only to refine below 1 ms
* Added SRTO_LOSSMAXTTL to srt_getopt()
* Update SND loss list on lite ACK
Fixes
* Fixed catching exception from
CUDTUnited::connect_complete()
* Fixed missing vertical FEC/CTL packet
* Fixed bandwidth measurement on non-monotonic or
retransmitted packets
* Fixed srt_getopt(...): optlen is not set in some cases.
* Fixed EPoll update_usock
* Fixed checkTimers interval (100ms -> 10 ms)
* Fixed SRT Stats backward compatibility (CBytePerfMon
fields order)
* Fixed FEC crash when a large number of dropped packets
occur
* Fixed FEC crash (access item out of range)
* Fixed FileCC crash. Prevented 0 pktsInFlight to be used in
the calculation for loss percentage
version 1.4.0:
New Features and Enhancements
* Updates to epoll API. Added edge-triggered epoll wait.
* srt-live-transmit default chunk size set to 1456
* Added forward error correction (FEC) packet filter
* Added Packet filter API
* File congestion control improvements
Fixed Issues
* Free addrinfo if bind fails (potential memory leak)
* Fixed SRTO_LOSSMAXTTL option on accepted socket
* Fixed blocking srt_connect call (state update)
* Fixed potential sender's sockets list overflow
* Use MONOTONIC clock in Garbage Collector thread
- Drop CVE-2019-15784.patch (fixed upstream)
OBS-URL: https://build.opensuse.org/request/show/839996
OBS-URL: https://build.opensuse.org/package/show/multimedia:libs/srt?expand=0&rev=24
- Add pkgconfig(zlib) BuildRequires: until openssl 1.1.1, zlib was
pulled in into our buildroot, avoiding srt having to care for it
explicitly. Since this is changed now, we have to worry for our
dependency on our own. The dep comes from:
CMakeLists.txt:set (SSL_REQUIRED_MODULES "openssl libcrypto zlib")
without this, we end up with a -devel package without the relevant
pkgconfig(foo) buildrequires (as pkg-config can't parse a .pc file
without the Requires: satisfied)
This will solve the ffmpeg-4 failure curently seen in Staging:C (openssl 1.1.1 upgrade)
