Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

6.12.0 - 2019-10-14

Added

  • Added support for the empty candidate that Firefox sends to signal the end of Trickle ICE.
  • Resolve mDNS candidate names that Chrome uses in place of local candidate IP Addresses for privacy reasons.
  • New package kurento-dbg, that installs all optional debugging symbols that are needed for Kurento crash reports.
  • Add support for compilation with Clang and UndefinedSanitizer in the Kurento helper build script: Kurento/kms-omni-build/bin/kms-build-run.sh.

Changed

  • libsrtp fork updated to version 1.6.0; custom patch reviewed to fix "unprotect failed code 9" warning messages.
  • User kurento gets now created with an User ID belonging to the system category (which gets an UID >= 100), instead of the user category (which gets an UID >= 1000). This fixes the issue of the user kurento showing up in the Ubuntu login screen.
  • The home directory for the user kurento has been moved from /var/kurento to /var/lib/kurento, which complies with the Linux Foundation's Filesystem Hierarchy Standard (FHS).
  • Enable C++14 language spec. when building C++ code.

Deprecated

  • The old home directory for the user kurento, which was located at /var/kurento, is now re-created as a symbolic link to the new location in /var/lib/kurento. Applications should migrate to the new location. The next major release of Kurento will stop providing the fallback link in the old path.

Fixed

6.11.0 - 2019-07-19

Added

  • Support new SDP syntax for SCTP medias (WebRTC DataChannels): kms-core#16.
  • Allow disabling IPv6 in kurento.conf.json.

Fixed

  • Fix several GStreamer memory leaks that caused constant increment of memory usage for each new WebRTC session: gst-plugins-bad!422.

6.10.0 - 2019-04-03

Starting from 6.10.0, all of these Kurento Media Server sub-projects:

  • kurento-module-creator
  • kms-cmake-utils
  • kms-core
  • kms-elements
  • kms-filters
  • kms-jsonrpc
  • kurento-media-server

have their ChangeLogs unified into this one.

Added

  • Support for Ubuntu 18.04. All build scripts and Debian packaging files were reviewed.
  • CMake helper to load Sanitizers (ASan, TSan, etc). This integrates https://github.com/arsenm/sanitizers-cmake
  • A new 'timestampMillis' field in RPC Event and Stats messages indicates the message timestamp with more precision than the old 'timestamp', which is now deprecated.
  • Support for MKV multimedia container has been added to the RecorderEndpoint, using H.264 for the video encoding. Thanks @prlanzarin (Paulo Lanzarin) for Kurento/kms-core#14, Kurento/kms-elements#13.
  • Improved the Troubleshooting Issues section with new cases. Thanks @tioperez (Luis Alfredo Perez Medina) for reporting #349 and sharing his results with RTSP and Docker.
  • Added support for AARCH64 architecture in the Death Handler library. Thanks @goroya for Kurento/kurento-media-server#10.

Changed

  • Use -std=gnu11 and -std=gnu++11 to enable C and C++ language versions with GNU extensions.
  • Use default build modes from CMake, only adding -Werror -O0 in case of Debug builds.
  • Rewrite the JSON parsing of settings files, to allow "inline comments" inside the JSON field names. Starting from Ubuntu 18.04, the underlying support library (Boost) doesn't accept comments in JSON any more; an alternative has been devised to overcome this limitation. Instead of commenting lines like before, it's now possible to write the comment marker "//" inside the field names. For example: "//name": "H264".
  • Clearer transcoding debug messages in the agnostic component (KmsAgnosticBin). Check out the 6.10 Release Notes for a detailed description of what changed.

Fixed

  • The GStreamer payloaders in KmsBaseRtpEndpoint and KmsRtpPayTreeBin were checking for the wrong data type before setting the config-interval property. Thanks @leetal (Alexander Widerberg) for reporting #321 and @prlanzarin (Paulo Lanzarin) for Kurento/kms-core#15.
  • Avoid setting NULL to port-range property in uridecodebin element when playing RTSP streams. This caused a segmentation fault due to a bug in GStreamer. Filed a patch in gstreamer/gst-plugins-good!64. Thanks @823639792 for reporting #325.
  • Catch proper exceptions on parse error for settings files. Before, parsing errors would pass silently.

6.8.1 - 2018-10-23

Fixed

  • Service init files will now append to the error log file, instead of truncating it on each restart.

6.8.0 - 2018-09-26

Added

  • GLib logging messages are now integrated with Kurento logging. This means that it's possible to save debug messages from libnice, together with the usual logs from Kurento / GStreamer.

Changed

  • Output logs now use standard format ISO 8601.
  • disableRequestCache is now exposed in settings file (kurento.conf.json). This can be used to disable the RPC Request Cache.
  • Clearer log messages about what is going on when the maximum resource usage threshold is reached.
  • File /etc/default/kurento-media-server now contains more useful examples and explanations for each option.

6.7.2 - 2018-05-11

Fixed

  • All: Apply multiple fixes suggested by clang-tidy.
  • Re-add redirection of 'stderr': log DeathHandler messages.
  • #245 (Possible SYN flooding): WebSocketTransport: Change default listen backlog to socket_base::max_connections.
  • #242 (libSSL crashes on mirrored packets): Debian: Remove dependency on our unmaintained fork of libSSL - Work In Progress.
  • Debian: Remove unneeded build dependency: binutils.
  • Debian: Use better defaults for logging levels.

6.7.1 - 2018-03-21

Changed

  • Raise version to 6.7.1.

6.7.0 - 2018-01-24

Changed

  • CMake: Compile and link as Position Independent Executable ('-fPIE -pie').
  • Add more verbose logging in some areas that required it.
  • Debian: Align all version numbers of KMS-related modules.
  • Debian: Remove version numbers from package names.
  • Debian: Configure builds to use parallel compilation jobs.

Fixed

  • Remove usage of 'sudo' from init script.

6.6.2 - 2017-07-24

Changed

  • Old ChangeLog.md moved to the new format in this CHANGELOG.md file.
  • CMake: Full review of all CMakeLists.txt files to tidy up and homogenize code style and compiler flags.
  • CMake: Position Independent Code flags ("-fPIC") were scattered around projects, and are now removed. Instead, the more CMake-idiomatic variable "CMAKE_POSITION_INDEPENDENT_CODE" is used.
  • CMake: All projects now compile with "[-std=c11|-std=c++11] -Wall -Werror -pthread".
  • CMake: Debug builds now compile with "-g -O0" (while default CMake used "-O1" for Debug builds).
  • CMake: include() and import() commands were moved to the code areas where they are actually required.

Fixed

  • Fix missing header in "server/loadConfig.cpp".
