Changes (since 4.7.5.01)

• Fixed an issue with DVR thread locking that caused failed chunk deliveries.
• Fixed an issue of incorrectly parsing AAC stream metadata from mp4 files and reporting the wrong audio sample frequency in MPEG-DASH MPDs. (E.g., reporting 24KHz instead of 48KHz)
• Fixed an issue of incorrectly using an audio samples-per-frame value of 1024 for all AAC and HE-AAC content, when HE-AAC audio should actually use a samplers-per-frame value of 2048.
• Fixed an issue that caused playback of HE-AAC HLS VOD content to fail in the Google Chrome browser when using HLS/MSE players such as JW Player, Bitmovin, and hls.js.
• Fixed an issue with periodically dropped audio frames in MPEG-DASH VOD audio chunks because of timecode rounding problem.
• Fixed an issue that caused Wowza Transcoder to crash when using an Opus encoder with audio resampling.
• Improved RTMP push publishing debug logging to include IO information.
• Added support for x-forwarded-for (XFF) and x-real-ip headers in HTTP requests.
• Restored the PushPublishUtils.getProfileUtilInstance() method that does not require an appInstance, but listed it as deprecated.
• Restored the IPushPublishProfileUtil.createGroupPlaylist() method, but deprecated it. Use UPushPublishHTTPGroupMember instead.
• Fixed an issue with application instance shutdown when using WebRTC.
• Fixed a WebRTC UDP port leak.
• Updated the HTTPStreamer/Properties httpMaxHTTPSessionsPerTCPSession property to support multiple HTTP streamer types.
• Updated dvrChunkIDByTimecodeHandler2 to prevent previous chunk IDs from being used.
• Fixed AMLST to correctly propagate IHTTPStreamerSession for all nDVR requests.
• Updated DVRChunkIDByTimecodeHandler2 to correctly start from zero when no nDVR stores are present.
• Fixed WebRTC thread exception that caused high CPU usage.
• Updated DvrMbrChunkIDByTimecodeResolver to split spans correctly.
• Fixed an issue with Akamai stream targets where Cupertino chunks smaller than 10-second durations would overload Akamai content directories.
• Changed nDVR chunk ID from int to long data type.
• Updated the default port for WebRTC ICECandidates to 1935.
• Restored addCORSHTTPHeaders (IHTTPResponse resp) method that doesn't require a request object in HTTPCORSHeaders.
• Added support for ingesting SHOUTcast and Icecast broadcasts as audio sources.

Changes (since 4.7.5 release)

• Fixed manifest so that it includes the quicksync-2017r3 libraries.
• Rebuild the Linux VPX encoder/decoder libraries to regain compatibility with CentOS 6.x distributions.
• Fixed SecureToken v2 to correctly support play2 requests for RTMP.
• Enhanced error checking and logging for serialization and deserialization of Common Encryption (CENC) data.
• Added support for MPEG-DASH ALS live streaming when ingesting low overhead audio stream (LOAS) audio lossless coding (MPEG-4 ALS) audio from an MPEG-TS stream.

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
• Added better debugging for MAC address locked licenses
• Fixed ability to run on Win8.1 native player by adding support for Smooth Streaming FragmentInfo requests in nDVR
• 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
