    Development Updates

    Between stable, production releases, Wowza periodically produces development builds in the form of updates. This allows you to try the latest releases of Wowza software to test and give feedback, and to get early access to new features. For more information about the latest Development updates, see Development Builds.

    Note: Development builds are not official releases and may not be stable.

    Wowza Streaming Engine 4.0.3

    The latest development build is Wowza Streaming Engine build 11497 (May 13, 2014)

    Wowza Streaming Engine (updates Wowza Streaming Engine 4.0.3.x to

    Changes (since 4.0.3 release)

    • Fixed NPE when decoding CEA-608 captions. Only occurs when live stream starts in middle of CEA-608 command sequence and first command happens to be a backspace
    • Fixed MPEG DASH MPD generation to guarantee that a unique ID is provided for all <Representation> elements in the manifest, per the DASH spec
    • Fixed PushPublishing 4.0 "rtmp-limelight" profile so that when the "application" config item is provided for a stream in the PushPublish map file, that app name is used in the Limelight ingest connection URL *instead of* the "userName"
    • Fixed a bug where you could not click "Connect" on an SDP file in Wowza Streaming Engine Manager and have the operation complete successfully
    • Fixed an exception that occurred during MPEG DASH live stream packetization when the codecs of both the audio and the video are unsupported.
    • Modified MPEG-DASH live MPD generation so that MPD@minimumUpdatePeriod is set to the offset between now and the time at which the next chunk should be available, such that the player could re-request the MPD at that point to see the new chunk
    • Modified the network interface selected for validating the REST API started to be the loopback interface when the REST Interface is set to bind on all addresses. This should improve startup performance on EC2 instances where the internal 10.x IP was being utilized incorrectly causing a long delay in the Streaming Engine server startup while the connection timed out
    • 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 ability to low level push publishing API to set the local bind address to control which NIC is used for TCP connection
      • PushPublishRTMP.setBindAddress(String bindAddress)
    • Added support for the "localBindAddress" configuration item in the PushPublish map file, which allows the user to specify which network interface should be used per RTMP output stream connection. Useful on installations with multiple NICs
    • Updated transcoder to MainConcept SDK version 9.8.0
    • Added transcoder decoding parameters for MainConcept H.264, MP2 and MP4 decoders
      • mainconcept.optCPUNum
      • mainconcept.optSMPMode
      • mainconcept.optACCMode
    • Fixed problem flushing onCaption CEA-608 style captions. Behavior was that caption appeared delayed from expected time
    • Fixed an issue with transcoder MainConcept H.264, MP2 and MP4 decoder that was causing corrupt frames on specific hardware platforms (set default value for CPU_NUM to 4)
    • Fixed issue where the manager would not allow a multi-line license key to be added
    • Fixed DVR edge receiver to not reset itself when origin stream is unpublished. This fixes behavior where unable to play back DVR from edge for a period after encoder disconnects from origin
    • Improved logic to pull captions from 608 decoder as close to display time as possible
    • Improved transcoder MainConcept default decoder initialization for MP2, MP4 and H.264
    • Added stream context to CEA-608 debug level logging
    • 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
    • Added additional logging to transcoder to log changes in decoded frame size
    • Improved transcoder video frame buffer to properly deal with NULL frame allocations
    • Fixed playback of DASH ABR from edge servers using smil files so that a request to the edge initiates streaming of all associated streams from the origin
    • Fixed wms.sh (service script) referencing old version of XStream, preventing license update server from working correctly when using this script to launch WSE and entering a bad license key
    • Lowered tolerance of fragment duration grouping nDVR HDS. Reduces buffering in OSMF player
    • Added boolean HTTPStreamers/Properties property smoothRespondImmediatelyOnReadAheadFragmentNotReady, that when true, the smooth streaming adapter will return 412 HTTP result immediately if fragment is not ready but it in read ahead list, if false will wait for 12 seconds for fragment to be available (default is false)
    • Added integer HTTPStreamers/Properties property smoothReadAheadFragmentNotReadyStatus that controls the HTTP status returned in above condition (default is 412)
    • Added checking in transcoder frame size calculations to be sure frame width and frame height are not less than 4 or greater than an 8k video frame
    • Added boolean Transcoder/Properties useVHostThreadPool to control which thread pool mechanism is used for transcoder worker threads (default is false which uses single thread pool mechanism)
    • Fixed Push Publishing so that an RTMP publish session is properly closed when the associated source stream is disconnected, in particular for the case where the RTMP session is in a reconnection loop
    • Fixed an NPE when trying to pass thru AC3 audio using Push Publishing
    • Fixed AC3 pass thru support for Push Publishing
    • Fixed transcoder issue on Linux that lead to transcoding threads hanging on startup
    • Changed Push Publishing version string to remove the duplicated version info at the end of the string now that it is built in (long string may have been causing issues with pushing to Akamai)
    • Rebuilt transcoder libraries on Linux
    • Added workaround for Push Publishing issue where on some systems a network outage results in the server not being able to reconnect some output RTMP streams due to persistent errors resolving the hostname.
    • 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
    • Increased the maximum video frame size before breaking frames into multiple PES frames for cupertino live stream packitizer from 32725 to 65477 bytes to improve decoding by non IOS devices on high bitrate streams
    • Added support for cupertinoAlwaysSendZeroPacketLen Cupertino live stream packetizer property in the Wowza Streaming Engine Manager
    • Fixed DVR UTC playlist delegate to use format yyyyMMddHHmmss instead of yyyy-MM-dd-HH:mm:ss, which was not getting properly encoded and parsed in chunklists and media lists due to the use of dashes and colons
    • Added log warning in DVR UTC playlist delegate if format contains colons, dashes or underscores
    • Fixed the Push Publishing Akamai-Cupertino profile so that adaptive group playlists will still be generated and pushed to Akamai even when the source and destination stream names don't match for a stream entry in the map file.
    • Fixed Apple HLS SAMPLE-AES encryption method to properly encrypt AC-3 pass through streams for both VOD and live
    • Fixed issue where DVR would fail to resume recording in some cases when ingest stream connection went away for a period of time
    • Downgraded transcoder scaler library from 9.8.0 to 9.5.0 to avoid threading issue
    • Modified CrontabEvent debug date string to include milliseconds
    • Modified LiveStreamRecordFLV and LiveStreamRecordMP4 to print out the current time when file is segmented occurs and debug is enabled
