Wowza 4.0.1 (Wowza Streaming Engine) Released!

 
Wowza 4.0.1 (Wowza Streaming Engine) Released!  A day after I installed #Wowza 4.0 ^_^'
What's change from 4.0 (version 4.0.1)
  • Added License key validation in the Wowza Streaming Engine Manager to prevent Wowza Media Server 3 keys being entered in a Wowza Streaming Engine 4 install
  • Added Streaming Engine & Streaming Manager support for MPEG-DASH packetization properties: mpegdashChunkDurationTarget, mpegdashMaxChunkCount, mpegdashPlaylistChunkCount, & mpegdashRepeaterChunkCount
  • Fixed an issue where Media Cache sources was storing TTL data as seconds instead of milliseconds
  • Turned off REST API for Central Configuration AddOn
  • Fixed incorrect usage of property cupertinoVODCaptionsUseWebVTT for live WebVTT CC when using smil or amlst. Now correctly uses cupertinoLiveCaptionsUseWebVTT

  • Removed PlayReady DRM info that was inadvertently being added to the PlayReady header for Apple HLS and MPEG-DASH

  • Fixed AC-3/E-AC-3 audio in MPEG DASH.
  • Fixed MPEG DASH issue where AudioChannelConfiguration MPD element was incorrectly being defined in the AdaptionSet container instead of the Representation container (VOD and Live).

  • Added support for 'mehd' box in DASH initialization segments.
  • Added AC-3 & E-AC-3 support in MPEG DASH streaming.
  • Fixed DASH-CENC issue where multiple keys in a key file caused no KeyId to be stored in the associated PlayReadyKeyInfo object.
  • Added MPEG DASH support so that it handles the case where an error occurs while indexing a VOD file, which previously would cause an exception later while trying to build a manifest.
  • Fixed the DASH players to allow audio-only and video-only playback.

  • Completed support for multiple DASH CENC DRM keyserver entries in a single key file. Also completed support for DASH CENC automatic PlayReady checksum and content-key generation based on the keyID and seed information provided in key file.

  • Added Common Encryption (CENC) classes for use by MPEG-DASH vod/live streaming.

  • Improved MPEG-DASH repeater logging to include context information
  • Fixed handling of "mpegDashChunkDurationTarget" property so that the value of the property defined under Application.xml:HTTPStreamer/Properties does not stomp on the value of the same-named property defined under Application.xml:LiveStreamPacketizer/Properties, during live DASH manifest generation. The value under HTTPStreamer/Properties is only supposed to be applicable VOD DASH streaming.
  • Removed DASH code looking for old "chunkDurationTarget" property in lieu of more specific "mpegdashChunkDurationTarget".
  • Implemented MPEG-DASH Live Stream Repeater (Origin-Edge)
  • Tweaked DASH manifest default so that the IMPEGDashConstants.PROFILE_DEFAULT value is used when no profile is specified in the mpd filename.
  • Changed the name of the MPEGDASH notification functions in the IBuyDRMStreamActionNotify interface.
  • Fixed DASH livestreampacketizer initialization method so that DASH-specific properties are only permitted in the LiveStreamPacketizer section of Application.xml, not at the app level properties. Also added support for the maxChunkLogCount property in DASH.
  • Added missing IModuleOnHTTPMPEGDashStreamingSession interface.
  • Modified MPEGDASH HTTP streamer to return Access-Control headers required by javascript players on ALL 4xx status returns.
  • Disabled noisy logging during live MPEG-DASH streaming when using the time-based profile.
  • Fixed issue in DASH test player so that when an incompatible video or audio codec is received, a more useful alert is reported and the UI does not hang.
  • Added calls to the new player.stop() function in the DASH example players so that the rogue MPD update timers get stopped as expected.
  • Added DASH logging for case where stream is requested that doesn't exist.
  • Fixed an exception in the Verimatrix module DASH APIs that occurred when a stream map file did not define a KeyId for a specific position in the key rotation (for DASH). It now reports warning in the logs.

HTTP Streaming (General)
