Encoding Encoder Releases

Latest Releases

Date

Version

2/22/2022

2.110.0

Added

  • AV1 encodings support now the following codec presets:
    • VOD_QUALITY - Higher quality
    • VOD_STANDARD - Default quality and speed
    • VOD_SPEED - Faster encoding

Fixed

  • Encodings configured with Dolby Vision and Fmp4Muxing in combination with fractional frame rate (example: 23.976, 29.97 and 59.94 fps) input could have lead to out of sync output(s).
  • Subtitle segments were not split for KeyFrames during 3-pass encodings.
  • 3-pass encodings could have failed on GCE for specific assets

Known Issues

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

2/8/2022

2.109.0

Added

  • Per-Title is now available for AV1 encodings to create the optimal bitrate ladder for each asset

Known Issues

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

2/1/2022

2.108.0

Added

  • Manifest Generator V2 is now available for single-encoding SMOOTH manifests by specifying manifestGenerator=V2 in the SMOOTH Start-Manifest Request. The minimum encoder version for that feature is 1.108.0. Differences to the LEGACY generator include:
    • V2 now correctly sets the "QualityLevels" attribute in the StreamIndex elements to the count of QualityLevel elements present.
    • V2 now correctly sets the "Index" attribute in the QualityLevel elements by increasing the number with each element.

Fixed

  • Improved handling of intermittent networking issues during encoding to prevent stalling
  • Fragment default values are now set in each traf box of the segments and not in the trex box of the init file for fMP4 muxings for Dolby Digital and Dolby Digital Plus audio codecs which caused playback problems on Roku streaming devices.

Known Issues

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

1/25/2022

2.107.0

Added

  • Cloud Region AWS_EU_NORTH_1 (Stockholm) is now available for encoder version 2.107.0 and newer.

Fixed

  • If the quality metadata (createQualityMetaData) was activated for a DASH stream and the file extension of the init file was modified to be something other then "mp4", the mimeType of the init file was set to "application/octet-stream" instead of "video/mp4".
  • Fixed an bug in the V2 HLS manifest generation with ProgressiveTs and TsMuxings which contain a video and an audio stream which lead to incorrect codec strings in the master playlist.

Known Issues

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

1/18/2022

2.106.0

Fixed

  • Sprites with creationMode=INTERVAL_START are now always generated, even if the input duration is shorter than the chosen Sprite's distance. For example, distance is set to 10s but video is only 8s long, this will result in a sprite with two images, the first and the last frame.
  • Bugfix for a rare case when multiple input and output audio streams are used with concatenation.

Known Issues

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

1/11/2022

2.105.0

Added

  • MP4 and fMP4 muxings can now be used for AV1 encodings. The following combinations are now supported with AV1:
    • DASH manifests
    • fMP4 with Widevine and PlayReady
    • MP4, fragmented MP4, WebM, and ProgressiveWebM with Widevine
    • MP4 with support for muxing video and audio together
  • AV1 turnaround times are now up to 30% faster
  • Added PTSAlignMode to fMP4 muxings. Setting it to ALIGN_ZERO_NEGATIVE_CTO will shift the first composition time offset (CTO) to 0. If B-frames are used, some CTOs will be negative. Therefore, TrackRun (trun) version 1 atoms are being used. This can only be set for h.264 and h.265 streams.

Known Issues

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

12/21/2021

2.104.0

Added

  • 3-pass can now be used for AV1 encodings to achieve optimal bitrate distribution

Known Issues

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

12/14/2021

2.103.0

Fixed

  • Fixed a bug where HEVC encodings with long input files could fail.

Known Issues

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

12/7/2021

2.102.0

Changed

  • Improved the generation of sprites, thumbnails and BIFs when using the Per-Title algorithm. Now, these additional resources are generated only for the rendition which has the highest resolution and bitrate to prevent duplicate generation.

Fixed

  • Fixed a bug in the manifestGenerator V2 that caused manifests with SPEKE DRMs to fail when creating a manifest via the startEncoding call and configuring the V2 ManifestGenerator.

Known Issues

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

11/30/2021

2.101.0

Fixed

  • 3-pass encodings could have violated the HLS specification 1.30 where "Max-Bitrate should be no more then 200% of AverageBitrate" when the last segment was only a few frames long. The Max-Bitrate calculation was now adapted to respect that very short segments typically have a very big bitrate value.

Known Issues

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