Date

Version

Beta

5/11/2021

2.76.0

Added

  • Added support for additional Sprite features so that they can be used for trick-play with DASH manifests. It's now possible to additionally specify the tile format (hTiles/vTiles), JPEG quality and a creation mode.

  • Added Image adaptation sets for DASH manifests with Sprite representations to enable video players to provide tiled thumbnails based on Sprites.

Fixed

  • Fixed a bug which could lead to incomplete progressive subtitle output in case that multiple progressive subtitle outputs were configured for the same stream.
  • Fixed an issue related to audio/video sync which could have occured under rare conditions if segmented and progressive muxings are mixed and the input frame-rate is variable.

Known Issues

  • S3 role-based output for segmented muxings: No upload verification available.

5/4/2021

2.75.0

Added

Fixed

  • Fixed some internal errors that occured for progressive muxings when both fragment length and GOP size have been configured
  • A memory leak has been fixed that caused live encodings to fail after several hours.
  • Fixed a bug where PerTitle's complexity factor was not applied to streams with StreamMode.PER_TITLE_TEMPLATE_FIXED_RESOLUTION_AND_BITRATE.
  • Fixed a bug where the Live Stop Rest Request wasn't processed correctly if the encoding is just starting up.

Known Issues

  • S3 role-based output for segmented muxings: No upload verification available.

4/27/2021

2.74.0

Added

  • Updates in the internals of the TTML to WebVTT subtitle conversion:
    • Added support for basic styling in TTML to WebVTT subtitle conversion, configurable via WebVttConfiguration
    • Added support for ChunkedTextMuxing in TTML to WebVTT subtitle conversion: allows to output segmented WebVTT files

Changed

  • Adapted internal Dolby Vision processing for encodings from J2K mezzanine files for workflows with segmented muxings

Fixed

  • Fixed a rarely occurring timing problem at the MP4 muxing step, which caused the encoding to fail.
  • Packed Audio segmentlength reverts to default 4.0 seconds.
  • Improved validations and error messages for invalid pixel formats and color configurations.
  • General stability improvements for multi-pass encodings on AWS cloud

Known Issues

  • S3 role-based output for segmented muxings: No upload verification available.

4/20/2021

2.73.0

Added

Fixed

  • To avoid rate exceeded errors for assuming IAM roles, caching of temporary credentials for the S3 role-based authentification process was introduced
  • A bug with the generation of HLS manifests for LIVE encodings has been fixed, were floating-point segment lengths were rounded down.

Known Issues

  • S3 role-based output for segmented muxings: No upload verification available.

Stable

5/5/2021

2.72.2

Fixed

  • A race-condition that could result in encoding jobs to fail in rare circumstances has been fixed.

Known Issues

  • S3 role-based output for segmented muxings: No upload verification available.

4/28/2021

2.72.1

Fixed

  • A bug has been fixed that caused live encodings to fail after several hours

Known Issues

  • A race-condition can result in failing encoding jobs in very rare cases
  • S3 role-based output for segmented muxings: No upload verification available.

4/13/2021

2.72.0

Added

Known Issues

  • Live encodings may fail after several hours! This issue was resolved in Version 2.72.1
  • S3 role-based output for segmented muxings: No upload verification available.

4/7/2021

2.71.0

Added

  • Improved bitrate distribution of VP9 encoded bitstreams in 3-pass encoding mode: The spikiness in the bitrate distribution, and consequently quality fluctuation in certain frames, in specific usecases has been reduced.
  • Region europe-west3 is now supported in GCE cloud
  • V2 manifest generator (BETA)
    • Added support for the mode selector in DASH manifest representations when manifests are generated via specifying them in the StartEncodingRequest.

Known Issues

  • S3 role-based output for segmented muxings: No upload verification available.

3/30/2021

2.70.0

Added

Known Issues

  • S3 role-based output for segmented muxings: No upload verification available.

3/23/2021

2.69.0

Fixed

  • Removed cue identifiers from WebVtt input if cueIdentifierPolicy is set to OMIT_IDENTIFIERS when using Chunked WebVtt muxing.
  • Fixed rounding in target duration calculation based on segment length for HLS manifests.

Known Issues

  • S3 role-based output for segmented muxings: No upload verification available.
