Encoding Encoder Releases

Latest Releases

Date

Version

6/18/2019

2.21.0

Added

  • Added parameter interval to the Thumbnails endpoint to create thumbnails every x seconds
  • Provides better turnaround times for encoding jobs, especially with 4k content and several output renditions
  • Enable muxing of E-AC-3 audio streams with BroadcastTS

Fixed

  • Improved writing of audio backup for SRT and Zixi live ingests after a disconnect.
  • Several stability improvements for 4k encoding jobs

Known Issues

  • Per-Title encodings only work with GCS, S3 or Akamai NetStorage output

Beta

6/4/2019

2.20.1

Fixed

  • Thumbnails and Sprites might have failed when not using GCS, S3 or Akamai NetStorage output and the thumbnail position is out-of-bound

Known Issues

  • Per-Title encodings only work with GCS, S3 or Akamai NetStorage output

6/4/2019

2.20.0

Added

  • Added support for HE-AAC audio codec with FairPlay encryption and fMP4 muxing
  • Added additional codec settings to VP9: errorResiliencyEnabled, clientBufferSize, clientInitialBufferSize, biasPct, cpuUsed, automaticAltRefFramesEnabled, targetLevel, rowMultiThreadingEnabled
  • Improved speed up for live encoding restart
  • Improved Broadcast TS muxing error detection
  • Added Akamai MSL Qualification for CMAF Dash
  • Increased stability for multiple input files feature

Fixed

  • Preview manifests were not created when input was missing audio
  • PSNR data for a stream was occasionally not created
  • Live Encodings might still occur as running from the API status call, although they have been stopped and shut down
  • Fixed an error with frame rate detection of variable FPS WebM input files
  • Fixed a decoding error with PCM DVD audio codec
  • Fixed a stalling issue with Akamai MSL upload

Known Issues

  • Per-Title encodings only work with GCS, S3 or Akamai NetStorage output
  • Thumbnails and Sprites may fail when not using GCS, S3 or Akamai NetStorage output and the thumbnail position is out-of-bound

5/22/2019

2.19.0

Added

Fixed

  • Progressive muxings with a space in the file name will not fail anymore
  • Broadcast TS muxings with audio only will not fail anymore
  • Per-Title encoding with many fixed resolutions was exceeding maxBitrate setting.
  • Correctly copy primaries, transfer characteristics and colorspace for files where they are signaled in the container format only, but not in the bitstream.
  • Filler data are retained when setting nalHrd=CBR in the codec settings.
  • MP4 muxings had PPS signaled on every keyframe which is not required and was leading to problems for some JIT packaging solutions.

Known Issues

  • Per-Title encodings only work with GCS, S3 or Akamai NetStorage output
  • Thumbnails and Sprites may fail when not using GCS, S3 or Akamai NetStorage output and the thumbnail position is out-of-bound

5/10/2019

2.18.5

Fixed

  • Setting long values for HEVC codec parameter masterDisplay was leading to failed encodings
  • Enhanced graceful handling of decoding errors for ProRes video codec

Known Issues

  • Per-Title encodings only work with GCS, S3 or Akamai NetStorage output
  • Thumbnails and Sprites may fail when not using GCS, S3 or Akamai NetStorage output and the thumbnail position is out-of-bound

5/3/2019

2.18.4

Fixed

  • Different segment lengths or fragment durations configured on muxings of one encoding job will be handled correctly and not lead to the segment length of the output to be signaled incorrectly. - The GOP lenght of a video stream will be set to the greatest common divisor of all configured segment and fragment lengths.

Known Issues

  • Per-Title encodings only work with GCS, S3 or Akamai NetStorage output
  • Thumbnails and Sprites may fail when not using GCS, S3 or Akamai NetStorage output and the thumbnail position is out-of-bound

5/1/2019

2.18.3

Fixed

  • Fixed Akamai NetStorage to not produce incomplete segments if maximum parallel connections are exceeded
  • Upload failures for Akamai NetStorage will be propagated via the API correctly and let the encoding job fail

Known Issues

  • Per-Title encodings only work with GCS, S3 or Akamai NetStorage output
  • If different segment lengths or fragment durations are configured on muxings of one encoding job, the segment length of the output can be signaled incorrectly which leads to invalid DASH/HLS manifests
  • Thumbnails and Sprites may fail when not using GCS, S3 or Akamai NetStorage output and the thumbnail position is out-of-bound

4/30/2019

2.18.2

Fixed

  • Enhanced upload resiliency to Akamai NetStorage by improving the retry mechanisms on upload failures that were caused by a huge amount of concurrent uploads.
  • Segment duration of audio streams was incorrect (too long or too short) if both sample rates 44.1 kHz and 48 kHz where mixed in one single encode job.
  • Speedup of Per-Title analysis by up to 40%

Known Issues

  • Per-Title encodings only work with GCS, S3 or Akamai NetStorage output
  • Upload to Akamai NetStorage could produce incomplete segments if maximum parallel connections are exceeded without the encoding job failing.
  • If different segment lengths or fragment durations are configured on muxings of one encoding job, the segment length of the output can be signaled incorrectly which leads to invalid DASH/HLS manifests
  • Thumbnails and Sprites may fail when not using GCS, S3 or Akamai NetStorage output and the thumbnail position is out-of-bound

4/25/2019

2.18.1

Fixed

  • fMP4 muxings with applied DRM AC3 and EAC3 streams did not get encrypted
  • When running many encodings in parallel for a specific region, the encoding cluster might get too less worker nodes, which slows down the encoding process

Known Issues

  • Per-Title encodings only work with GCS, S3 or Akamai NetStorage output
  • Thumbnails and Sprites may fail when not using GCS, S3 or Akamai NetStorage output and the thumbnail position is out-of-bound

4/24/2019

2.18.0

Added

  • Added detailed statistics for SRT ingest protocol
  • Added the flag writeDurationPerSample for fMP4 muxing to enable/disable writing a duration per sample. This is required for some legacy players.
  • Added support for Akamai MSL4 DASH output
  • Added ability to upload segmented WebVTT sidecar file

Fixed

  • Rate-control enhancement for 3-pass encoding in VP9 for improved quality distribution and to avoid drops in quality
  • Fixed Per-Title analysis errors for files where we could not extract correct timing information.

Known Issues

  • Per-Title encodings only work with GCS, S3 or Akamai NetStorage output
  • Thumbnails and Sprites may fail when not using GCS, S3 or Akamai NetStorage output and the thumbnail position is out-of-bound
