Encoding Encoder Releases

Latest Releases

Date

Version

Beta

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.

Stable

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.

11/23/2021

2.100.0

Added

Changed

  • AV1 encodings:
    • Speed - Encodings run now 5x faster.
    • Quality - Encodings now show appr. 30% higher quality when compared to HEVC/VP9 encodings.
    • Cost - Encodings are now significantly more cost effective. See our Encoding Minute Calculation Methodology for detailed pricing information.
  • CueIdentifierPolicy default for WebVttConfigurations for inputs with FileInputStreamType TTML and SRT: The default is now INCLUDE_IDENTIFIERS instead of OMIT_IDENTIFIERS.
  • Added startOffset to TextMuxing and ChunkedTextMuxing. This is used for setting the MPEGTS value for the RFC 8216 (HLS Specification) X-TIMESTAMP-MAP for WebVtt outputs (e.g.: X-TIMESTAMP-MAP=MPEGTS:900000,LOCAL:00:00:00.000).
  • WebVttConfigurations with CueIdentifierPolicy INCLUDE_IDENTIFIERS will now generate CueIds starting from 1 instead of 0 if the FileInputStreamType is WEBVTT.

Fixed

  • Streams with WebVttConfigurations will now be trimmed with the same offset and duration as the video stream of the same encoding if the FileInputStreamType is WEBVTT (This is the same behavior as TTML and SRT FileInputStreamTypes already used to have).
  • Fixed a bug which caused output subtitle cues' timestamps to be shifted by the value of the first video PTS, if FileInputStream is used for the subtitle stream
  • KeyFrames are now placed correctly for streams with WebVttConfigurations

Known Issues

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

11/16/2021

2.99.0

Fixed

  • Enhanced Deinterlacer potentially created distorted output for non-standard input resolutions.
  • Writing default manifests to Akamai Netstorage had failed

Known Issues

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

11/3/2021

2.98.0

Added

Changed

  • Improved the intra-segment rate-control mechanisms for VP9 encodes

Fixed

  • Potential truncation of last CUE in WebVTT outputs was fixed
  • Encodings using Widevine DRM have correct pssh content now

Known Issues

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