Detailed list of changes in Wowza Streaming Engine 4.7.1

Changes since 4.7.0.02 release

• Fixed parsing of AC-3 descriptor in MPEG-TS source streams
• Added validatePath to IHTTPProvider to enable requested content paths to be validated
• Updated Application and ApplicationInstance name verification
• Updated HTTP and RTSP streamer URL validation
• Updated the default JMX permissions to readonly
• Disabled Server.readConfig() and Server.writeConfig mbeans
• Updated HTTP provider HTTPProviderMediaList to validate provided stream names
• Updated default VHost.xml to remove HTTP provider HTTPProviderCaptionFile
• Fixed Microsoft PlayReady encryption to properly handle large fragments
• Fixed CORS headers for Apple HLS and range requests
• Updated liverepeater MediaCaster when streamForceResetOnReconnect is enabled
• Fixed Wowza nDVR out-of-bounds exception when segments are empty
• Added REST endpoint /v3/servers/{serverName}/vhosts/{vhostName}/applications/{appName}/instances/{instanceName}/incomingstreams/{streamName}:
  • Added parameter streamRunningTime, which specifies how long the stream has been running in seconds
  • Added parameter isAudioReady, which specifies the audio codec config packet count from the packet queue
  • Added parameter isVideoReady, which specifies the video keyframe count from the packet queue
• Improved error handling for HTTPByteWriter and HTTPSByteWriter to avoid exceptions when data can’t be written correctly

Stream Targets (Push Publishing)

• Fixed several issues with how PushPublishManager API interacted with PushPublish module when adding and deleting stream targets
• Fixed destination stream name generation for Wowza CDN stream targets to follow [stream_name]_1_[bitrate] format as is used for Wowza Streaming Cloud stream targets
• Fixed issue with incorrect generation of destination stream names for Wowza CDN and Wowza Streaming Cloud stream targets
• Fixed Stream Targets PushPublishHTTPCupertino base class so that after a media segment is pushed, the actual chunk object reference that’s held by the associated MediaSegmentModel is cleared, instead of just the chunk’s fragments list
• Fixed HTTP stream target profiles (for HLS, HDS, and MPEG-DASH) so that they don’t show adaptive (ABR) groups as being “ready” until they have a populated chunklist, avoiding the “Failed to create group playlist for group…” log that would appear at the beginning of the ABR push session(s)
• Fixed Wowza Streaming Engine Manager so that errors that occur while deleting Wowza CDN stream targets are handled properly and a failure message is displayed on the Stream Targets page
• Fixed PushPublishHTTPCupertino base class so that when a target has no playlist/chunklist built yet and a disconnect() occurs, it doesn’t generate an NPE
• Fixed Akamai HLS/HDS/MPEG-DASH stream targets to properly handle relative playlists when an eventName is defined for the target

Live Stream Recording

• Fixed LiveStreamRecord synchronization to prevent segmentation failures
• Added Application/Properties property liveStreamRecorderDebugAACTimecodes (Boolean, default=false) that enables debugging of AAC timecodes when recording to a file

Live Stream DVR Playback (Wowza nDVR)

• Fixed nDVR Converter REST Swagger documentation to include the dvrConverterStoreList parameter, which is required by the DvrRESTConverterStoresAction API
• Fixed nDVR Converter API so that it honors the dvrConverterDefaultFileDestination parameter
• Fixed nDVR 404 playlist responses so they include CORS headers
• Fixed Wowza Streaming Engine Manager where we showed “not supported when Only DVR Streaming is enabled” for the MPEG-DASH playback type (on application Setup tab) any time when “DVR streaming only” is selected in nDVR configuration, even when nDVR is disabled
• Added query parameter dvrConverterInterleaveDelay to the nDVR REST API for store conversions to control I/O saturation time
• Fixed nDVR conversion for audio-only streams when using a start offset
• Improved nDVR REST API endpoint to report when a conversion is already in progress
• Improved nDVR store error handling when invalid data is encountered

MediaCasters, Stream Files, and Startup Streams

• Added MediaCaster/Properties property streamForceResetOnReconnect (Boolean, default = false) to force a complete unpublish/republish of a stream when a live repeater connection is reset
• Fixed applehls mediacaster fetch timers so they don’t overcompensate when large delays occur
• Fixed applehls mediacaster retry logic to correctly retry within the defined limits
• Fixed applehls mediacaster when playlist retrieval results in an unparseable response
• Updated liverepeater MediaCaster to unpublish/republish when forceReset is called using the reconnectWaitTime parameter
• Updated streamfiles/{streamfileName}/adv endpoint changing RTPTransportMode to interleave to match default Application.xml configuration

WebRTC (Preview)

• Added the following H.264 WebRTC constraints override properties (they should only be used when WebRTC is being used):
  • Added Application/RTP property rtpForceH264Constraint (Boolean, default=false) to override the constraints value for H.264
  • Added Application/RTP property rtpForceH264ConstraintValue (Integer, default=192) to set the override constraint value (only the top 4 bits MUST be set)
• Added the following H.264 WebRTC constraints properties (these should only be used when WebRTC is being used):
  • Added Application/RTP property rtpUseLowestH264Constraint (Boolean, default=false) to force the use of the lowest constraint information found in an H.264 video stream
  • Added Application/RTP property rtpUseHighestH264Constraint (Boolean, default=false) to force the use of the highest constraint information found in an H.264 video stream

RTSP/RTP Streaming

• Fixed Application/RTP property rtpForceH264Constraint so it can be set independently to rtpUseLowestH264Constraint and rtpUseHighestH264Constraint
• Added Application/RTP property resyncAudioVideoOnSRLogStreamSuffix (String, default not used) that allows timecodes from transcoded streams to be logged when resyncAudioVideoOnSRLog is enabled
• Improved RTSP/RTP playback to properly handle Streams/Properties instanceOn and instantOnBufferTime

General/Other

• Fixed bad XML in Akamai DASH manifest for audio Adaptation Set with DRM
• Added default Sample Frequency (8000) for PCM audio when creating SDP entries
• Fixed SCTE parsing to correctly return splice information
• Added IWebSocketEventNotify2.onIdle(IWebSocketSession webSocketSession) handler to websocket event interface to enable hooking into idle events
• Improved liverepeater-lowlatency stream type to properly set low-latency stream settings
• Added live stream receiver log statement on stream startup to log more information about live stream settings such as sort buffer and onFlushNotifyClient
• Improved error handling for HTTPSByteWriter to avoid exceptions when hostname/remote servers aren’t available
• Fixed Server Name Identification (SNI) configuration so that variable expansion works properly on the “DomainToKeyStoreMapPath” field in the host port SSL configuration as well as the “keyStorePath” field in DomainToKeyStoreMap.txt
• Fixed bug where an application shutdown request via REST or JMX interface occurring at the same time as an HTTP session timeout-shutdown could cause a deadlock
• Fixed H.264 MediaReader to correctly count atom entries to allow F4V file playback
