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.

6.10.0 - 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 in kurento-media-server/CHANGELOG.

6.8.1 - 2018-10-23

Fixed

  • GStreamerFilter: Allow using the 'textoverlay' filter.

6.8.0 - 2018-09-26

Added

  • Hub, HubPort: Add support for DATA streams.
  • GStreamerFilter now can set the inner element's properties "on the fly" during runtime.

Changed

  • Use kms_utils_element_factory_make() for better element names in debug graphs
  • ModuleManager: Review startup logging messages

Fixed

  • Agnosticbin: Send TRANSCODING signals only once
  • #144 AgnosticBin: FIXME Reconfigure pipeline
  • BaseRtpSession: Fix memory leaks
  • MediaSet: Fix unreleased memory on object unref

6.7.2 - 2018-05-11

Added

  • KmsBaseRtpEndpoint: New property "offer-dir", which allows to specify the SDP Offer direction when it gets generated by KMS.
  • KmsBaseRtpEndpoint: Don't reduce RTCP interval if REMB is not used.

Fixed

  • All: Apply multiple fixes suggested by clang-tidy.
  • #241 (Add 'a=setup' to SDP Offers).

6.7.1 - 2018-03-21

Added

  • agnosticbin: Add new signal "media-transcoding".
  • API KMD: Server implementation for event "MediaTranscodingStateChange".
  • MediaTranscodingStateChange: Write documentation.

Fixed

  • MediaPipelineImpl: Fix NULL dereferencing.

6.7.0 - 2018-01-24

Changed

  • CMake: Compile and link as Position Independent Code (fPIC).
  • 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

  • Reset stats after RTP source gets reconnected. The RTP sources assume a starting point of 0, so KMS must also adjust its own status after a reconnection.
  • #197 (Composite Hub making audio choppy) with PR#9 (kmsenctreebin.c use max-size-time instead of max-size-buffers), by @ruddell (Jon Ruddell).

6.6.3 - 2017-08-10

Changed

  • PR#7 (Prevent frames from building up in the buffer if the CPU falls behind), by @kc7bfi (David Robison).

6.6.2 - 2017-07-24

Added

  • REMB: Add "COMEDIA"/automatic port discovery. Documentation.
  • REMB: Enable for RTP connections. Previously, it would only work for WebRTC.

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.
  • REMB: Limit estimations to the "double of the max bitrate" only in increment phase.
  • REMB: Make "minVideoRecvBandwidth" always >= 30 kbps.

Fixed

  • Bugfix: Out of bound access on SDP medias.
  • PR#5 (Use format macros to fix compiler errors on 32bit systems), by @fancycode (Joachim Bauch).
  • When a non incremental PTS is discovered in an input stream, the internal DTS gets updated with the new PTS value.

6.6.1 - 2016-09-30

Changed

  • Improved thread management when using filters. Filter processing uses its own thread and drops packages that are late.
  • Improved compilation issues.

Fixed

  • Fix problem in PTS synchronization algorithm when remote is sending wrong RTCP SR packages that produces backwards PTS.

6.6.0 - 2016-09-09

Added

  • Support for UriEndpoint.
  • SDP Agent: Add support for error notification using GError, this allows raising betters exceptions to client.
  • ServerManager: Add method to get memory used by the server.

Changed

  • SDP Agent: Make code cleaner.
  • Improved RTP synchronization algorithm, this makes recorder behave better when recording from RtpEndpoint or WebRtcEndpoint.
  • Allow C++ to listen to signals with a return value.
  • Updated documentation.
  • UriEndpoint: Add property to get state.
  • UriEndpoint: Add event to notify state changes.

Fixed

  • Memory problems during Media Elements disconnections.
  • Memory problems in flowOut/flowIn events detection.
  • Memory leaks.
  • Rare media deadlocks on Agnosticbin.
  • Improved Media Elements connection, some cases were not working correctly, specially when creating multi stream elements.

6.5.0 - 2016-05-27

Added

  • Agnosticbin: Add support for RTP format (only at output).

Changed

  • Changed license to Apache 2.0.
  • Updated documentation.
  • REMB algorithm improvements.
  • Max/min video bandwidth parameters (now 0 means unlimited).
  • Raise events from differents threads.

Fixed

  • Bugs in Flow IN - Flow OUT event (caused a segmentation fault).

Deprecated

  • Changed some event/methods names and deprecated old ones (which will be removed on the next major release).

6.4.0 - 2016-02-24

Added

  • Prepare implementation to support multistream.
  • Add flow in and flow out signals that indicates if there is media going in or out to/from a media element.
  • Add leaky queue in filters to avoid them to buffer media if the proccess slower than buffers arrive.

Changed

  • Improve latency stats to add support for multiple streams.
  • REMB algorithm improvements.

Fixed

  • Bad timestamp for Opus codec.
  • Latency stats calculation.
  • Some problems in SDP Agent.

6.3.1 - 2016-01-29

Fixed

  • Fix problem with codec names written in lower/upper case.

6.3.0 - 2019-01-19

Added

  • SdpEndpoint: Add support for negotiating IPv6 or IPv4.
  • Add compilation time to module information (makes debugging easier).
  • KurentoException: Add exceptions for player.

Changed

  • Update Glib to 2.46.

Fixed

  • SdpEndpoint: Fix bug on missordered medias when they are bundle.
  • Agnosticbin: Fix many negotiation problems caused by new empty caps.
  • MediaElement/MediaPipeline: Fix segmentation fault when error event is sent.
  • Agnosticbin: Do not negotiate pad until a reconfigure event is received (trying to do so can cause deadlock).
  • SDP Agent: Support "mid" without a group (fixes problems with Firefox).
  • Fix problem with REMB notifications when we are sending too much NACK events.

6.2.0 - 2015-11-25

Added

  • RtpEndpoint: Add address in generated SDP ("0.0.0.0" was added so no media could return to the server).
  • SdpEndpoint: Add "maxAudioRecvBandwidth" property.
  • BaseRtpEndpoint: Add configuration for port ranges.
  • UriEndpoint: Add default uri for relative paths. Now uris without schema are treated with a default value set in configuration. Directory "/var/kurento" is used by default.

Changed

  • Update GStreamer version to 1.7.
  • RecorderEndpoint: Change audio format for WEBM from Vorbis to Opus. This is avoiding transcodification and also improving quality.

Fixed

  • Fixed #12 (Kurento/bugtracker#12)
  • SdpEndpoint: Raises error when sdp answer cannot be processed.
  • MediaPipeline: Add proper error code to error events.
  • MediaElement: Fix error notification mechanisms. Errors where not raising in most cases.
  • Improvements in format negotiations between elements, this fixes problems in RecorderEndpoint and Composite.
