========================================
Changes in Wowza Streaming Engine 4.1.0 Build 12602

	* Modified the Linux services code for stop and start rather then returning a status code as they have in the past. They will now return 0 for both stop and start. The status call will return a 0 for running and 3 for not running.
    * Added long property scalerMainConceptScaleMode available in Encoder/Properties to control the scale mode used in transcoder (0 = nearest neighbour, 1 = best (default), 2 = bilinear, 3 = polyphase8)
    * Added support in transcoder for double rate deinterlacing of H.264, MP2 and MP4 streams (enabled by adding long parameter with the name deinterlaceDoubleRate with a value of 1 to the Decode/Video/Parameters section of transcoder template, off by default)
    * Made SHOUTcast AAC group count property shoutcastAACGroupCount available in Streaming Engine Manager
    * Changed SHOUTcast default MP3 and AAC group count (shoutcastMP3GroupCount and shoutcastAACGroupCount) to 1 (previous value was 4)
    * Improved parsing of SCC caption files, allowing multiple whitespace characters between fields
    * Fixed problem with HEVC/H.265 VPS decoding leading to warning message about multiple VPS NAL units
    * Enhanced debug context for DVR MBR alignment logging to include aligner ID
    * Fixed problem with transcoder multi-threaded scaling throwing an error if only a single encoder output
    * Improved transcoder system to properly shutdown transcoder (and release license) when stream source is push publisher
    * Added Streams/Propertries boolean property transcoderShutdownOnClose to control when transcoder is shutdown (true: transcoder is shutdown when stream is closed, false: transcoder is shutdown when stream is destroyed, default to false except when source stream is push publisher)
    * Added some exception handling in the PushPublishing module where HTTP streams are being pushed to an endpoint
    * Updated colors to match between the protocol pie chart and the historic chart on the VHost and Application monitoring pages
    * Exposed the default value for securityPublishValidEncoders as "Flash Version String" in the Manager so users can replace or append to the list of allowed values
    * Fixed a PushPublishing cupertino-akamai bug that was keeping WSE from sending the HLS playlist file to akamai
    * Changed the default setting for importing AC3 streams via MPEG-TS to true
    * Fixed case where DVR ABR would not align correctly after packet time reset mid recording. This could sometimes result in segments of the DVR out of order or longer than expected playlists
    * Fixed an issue with reading the MPEG-TS PMT Stream Descriptors and the detection of AC3 streams
    * Changed parsing of flash version string to allow either pipe or comma delimiters   
    * Fixed PushPublishing HLS bug where an occasional race condition would cause an exception in the HLS chunk processing, which would cause a chunk to never get pushed to the destination
    * Fixed logic around selecting the correct vhost port for the test players in Streaming Engine Manager
    * Fixed issue where HLS AES encryption using smil files would not return correct internal encryption key
    * Added an MPEG-TS property mpegtsRemoveRepeatStartCodes that can be set to remove start codes that are repeated in the stream
    * Turned importing AC3 back to "false" as the default because we don't support AC3 in the transcoder.  We are concerned that this can adversely affect customers that have MPEG-TS streams with AC3 streams before their other audio streams in the PMT and we'll pickup the AC3 as the default
    * Fixed PushPublishing memory leak that would occur on every stream disconnect
    * Fixed PushPublishing RTMP connection logic so that all reconnection attempts always occur with a gradually increasing delay (up to 60 sec) between each attempt,  the same way it has historically worked for the initial RTMP tcp connection
    * Added support for enabling the HbbTV-specific live MPEG-DASH manifest profile definition using the mpegdashEnableHbbtvLiveProfile property
