Changes (since 4.7.2 release)

• Updated Secure Reliable Transport (SRT) libraries
• Fixed SRT implementation to handle Advanced Encryption Standard (AES) key parameters correctly

Changes (since 4.7.1 release)

Note: This Wowza Streaming Engine updater has a new MediaCaster type that enables live applications to ingest Secure Reliable Transport (SRT) source streams and make them available to all player technologies supported by the Streaming Engine software. SRT streams are only supported in Wowza Streaming Engine software on Linux at this time. To learn how to set up live applications to ingest SRT streams, see How to create and use .stream files in Wowza Streaming Engine Manager. For more information about configuring the ingest of SRT, see How to specify per-stream SRT settings in .stream files.

Latest updater for Wowza Media Server software

The latest updater for Wowza Media Server software is Wowza Media Server™ 3.6.4.05 build 13451 released on January 15, 2015.

Changes (since 3.6.4.02 release)

• Fixed bug with Apple HLS (cupertino) streaming by properly removing query string in URL before extracting Wowza session ID
• Fixed an issue with reading the MPEG-TS PMT Stream Descriptors and the detection of AC3 streams
• Fixed live WebVTT captions in HTTP Origin mode (wasn't returning captions in subtitlechunk)
• Fixed NPE when decoding CEA-608 captions. Only occurred when live stream starts in middle of CEA-608 command sequence and first command happens to be a backspace
• Fixed HLS WebVTT caption time format to only show 2 hour digits unless more are needed. This caused captions to be ignored when casting some players to ChromeCast
• Added integer HTTPStreamers/Properties property to control the maximum number of HTTP sessions that can be associated with a single TCP session (fixes file descriptor leak in the case where a single TCP session make many requests for the manifest over a single TCP connection, default is zero which is no limit)
  • httpMaxHTTPSessionsPerTCPSession
  • cupertinoMaxHTTPSessionsPerTCPSession
  • mpegdashMaxHTTPSessionsPerTCPSession
  • sanjoseMaxHTTPSessionsPerTCPSession
  • smoothMaxHTTPSessionsPerTCPSession
• Lowered tolerance of fragment duration grouping nDVR HDS. Reduces buffering in OSMF player
• Added Boolean LiveStreamPacketizers/Properties property cupertinoAlwaysSendZeroPacketLen that helps players other than the IOS Quicktime player decode high bitrate streams (with frames larger than 32K) when streaming Apple HLS. This will prevent video frames from being sent with multiple PES headers and the PES packet length will always be set to "zero". The default value is false
• Fixed incorrect usage of property cupertinoVODCaptionsUseWebVTT for live WebVTT closed captions when using SMIL or AMLST. Now correctly uses cupertinoLiveCaptionsUseWebVTT
• Fixed NPE when inserting WebVTT captions using AMLST if media list does not contain properties
• Fixed bug in LiveStreamRecorderMP4 where the more accurate audio packet timecodes were incorrectly calculated when packet timecodes jump backward
• Fixed support for mpegtsMapTimeToSystemTime which enable mapping incoming MPEG-TS timecodes to the system clock to enable multi-server stream alignment
• Fixed LiveStreamRecorderFLV log entries to report correct module, instead of LiveStreamRecorderMP4
• Fixed LiveStreamRecorderFLV media duration to report the full file duration, when appending to existing file, instead reporting the duration of last content added
• Fixed LiveStreamRecorderFLV and LiveStreamRecorderMP4 to correctly add packets to file when timecodes jump back in time and splitOnTcDiscontinuity is set to false
• Fixed LiveStreamRecorderMP4 excessive memory usage when recording a file without segmenting and timecodes jump backward in time and and splitOnTcDiscontinuity is set to false
• Fixed a RTMP playback issue with smart pause that caused corrupted playback if stream was paused for more than 60 seconds
• Fixed Memory leak in RTPSessonDescriptionDataProviderBasic when a valid SHOUTcast stream is connected using the invalid MediaCaster type of RTP
• ReFixed LiveStreamRecorderMP4 excessive memory usage when recording a file without segmenting and timecodes jump backward in time and and splitOnTcDiscontinuity is set to false
• Fixed bug where stream data quits writing to Segment file when timecodes jump back in time

Changes (since 3.6.4 release)

• Fixed internal packet handling algorithm to account for case where inner handler was both saving and flushing
• Added application-level Boolean property rtmpEncoderAuthenticationSendCloseOnRejectConnection to control if "close" command is sent during RTMP authentication process (default is false)

• Fixed bug in HTTPLiveStreamRecord output URL parameter handling where ${variables} for file names weren't getting replaced correctly
• Fixed Silverlight multicast authorizer to not start the worker thread if socket creation failed
• Updated bin/nssm_[x32,x64].exe service code to fix service restart issue
• Fixed FLV header to correctly report video present and audio present when recording using webcam app

• Fixed problem with Apple HLS encryption with onHTTPCupertinoEncryptionKeyVODChunk API not sending correct chunk index during playlist generation
• Fixed LiveStreamRecordFLV to use LiveStreamRecordFLV.class when logging instead of LiveStreamRecordMp4.class
• Added code to LiveStreamRecordFileVersionDelegate to ensure the TimeZone ID returned by the time formatter doesn't contain bad file characters, such as ":" , and if it does, use the offset from GMT instead
• Added the ability to override the default LiveStreamRecordFileVersionDelegate via an application.xml property
• Fixed DVR HTTP Origin mode problem where if first request is a chunk request, chunklist request would return 404
• Fixed recording problem with the second recording on a MediaStream
• Changed ModuleMediaWriterFileMover to use a new thread for its work so it doesn't block the calling thread
• Fixed ModuleMediaWriterFileMover to create a thread per stream and queue per thread to ensure file moving isn't interrupted by rapid publish/unpublishing events

  • cupertinoMPEGTSVideoPID
  • cupertinoMPEGTSAudioPID
  • cupertinoMPEGTSDataPID
• Added the following integer DVR properties to control the PID values used when streaming using Apple HLS (cupertino):
  • cupertinoMPEGTSVideoPID
  • cupertinoMPEGTSAudioPID
  • cupertinoMPEGTSDataPID
• Added ability for dvr[Smooth,Cupertino,SanJose]PlayerAdapter properties to come from HTTPStreamer or DVR Properties section of Application.xml
• Fixed Smooth HTTP Adapter debug logging. Wasn't properly hooked up to VHost properties smoothAdapterDebugLog or httpAdapterDebugLog
