Encoding Encoder Releases

Latest Releases

Date

Version

Beta

3/24/2020

2.42.0

Added

Fixed

  • Fixed an issue where fMP4 muxings reported an incorrect bitrate when using multiple outputs for the muxing

Known Issues

  • Per-Title encodings only work with GCS, S3, Generic S3, Akamai NetStorage or Azure Blob output.
  • Progressive MP4 with CBR encodings might have incorrect HRD buffer signaling.
  • S3 role-based output for segmented muxings: No upload verification available

3/10/2020

2.41.0

Added

Fixed

  • Encodings of MPEG2 source inputs with faulty interlaced packets, first field present but the second field absent, failed earlier. This is handled correctly now.
  • Encoding with mov containers containing an AAC audio stream without extradata failed earlier.

Known Issues

  • Per-Title encodings only work with GCS, S3, Generic S3, Akamai NetStorage or Azure Blob output.
  • Progressive MP4 with CBR encodings might have incorrect HRD buffer signaling.
  • S3 role-based output for segmented muxings: No upload verification available

Stable

3/4/2020

2.40.1

Fixed

  • Add correct cenc:pssh and mspr:pro elements to ContentProtection section of DASH manifests when using CENC PlayReady DRM for fMP4 muxings in live encodings.

2/25/2020

2.40.0

Added

  • Added support for the audio codec aac_latm (HE_AAC) for live ingest streams
  • Time-based trimming of inputs with a different offset value is now supported
  • Support CENC Widevine and CENC Clearkey for progressive WebM muxings and via SPEKE
  • CEA-608/708 captions from a separate input track can be added to a H.264 and HEVC video stream.
  • SCC Subtitles from a seperate text file can now be passed through into an HEVC output.

Fixed

  • Adapted the format of the cenc:default_KID in dash manifests to an UUID format for fMP4 muxings.
  • Fixed a rounding error which caused in rare cases that the DASH manifest contained one segment too much

Known Issues

  • Per-Title encodings only work with GCS, S3, Generic S3, Akamai NetStorage or Azure Blob output.
  • Progressive MP4 with CBR encodings might have incorrect HRD buffer signaling.
  • S3 role-based output for segmented muxings: No upload verification available

2/24/2020

2.39.0

Added

  • SCC to CEA 608/708 subtitle conversion for H265 codec configurations.
  • CEA 608/708 subtitle passthrough for H265 codec configurations via property cea608708SubtitleConfig.
  • Added sshPort and faspPort to Aspera inputs to be able to configure non-standard ports for session intialization and data transfer.
  • Customers using their own AWS account can now opt-in, so that all SSH communication comes from one specific IP address. This enables a more rigid network security policy where only one IP is whitelisted for SSH connections.

Fixed

  • Add correct cenc:pssh and mspr:pro elements to ContentProtection section of DASH manifests when using CENC PlayReady DRM for MP4 and fMP4 muxings.
  • CENC Marlin is now also applied to muxings generated by the Per-Title algorithm.
  • Enhanced stability of our 24/7 live encoders by fixing smaller memory leaks that led to failures on long-running streams.
  • Fixed an issue where the burn-in of subtitles stops after some time in long running 24/7 live encodings.
  • Improved sync of burn-in subtitles to audio/video streams. Reduced the risk of stalled encodings by making the transcoding tasks time-boxed.

Known Issues

  • Per-Title encodings only work with GCS, S3, Generic S3, Akamai NetStorage or Azure Blob output.
  • Progressive MP4 with CBR encodings might have incorrect HRD buffer signaling.
  • S3 role-based output for segmented muxings: No upload verification available

1/28/2020

2.38.0

Fixed

  • Fixed a bug that potentially produced SAMPLE-AES encrypted TS segments with non-monotonically increasing timestamps. (caused the segment to be silent in Safari browser)
  • Fixed a bug which prevented the update of DASH Live Manifests

Known Issues

  • Per-Title encodings only work with GCS, S3, Generic S3, Akamai NetStorage or Azure Blob output.
  • Progressive MP4 with CBR encodings might have incorrect HRD buffer signaling.
  • S3 role-based output for segmented muxings: No upload verification available

1/14/2020

2.37.0

Added

Fixed

  • Insertable Content no longer requires to have the same sample aspect ratio as the livestream. Additional requirement for Insertable Content: video stream must be at position 0 of the movie file.
  • Fixed bug which caused encoding to fail when setting stream conditions on Per-Title template streams.
  • Fixed an issue with audio codec detection on specific input files that lead to no audio and 2x video duration output.
  • Fixed bug that potentially caused stalled encodings in case that video filters were applied and several output renditions were encoded in parallel.

Known Issues

  • Per-Title encodings only work with GCS, S3, Generic S3, Akamai NetStorage or Azure Blob output.
  • Progressive MP4 with CBR encodings might have incorrect HRD buffer signaling.
  • S3 role-based output for segmented muxings: No upload verification available
  • Minimal chance of producing SAMPLE-AES encrypted TS segments with non-monotonically increasing timestamps for encodings with at least 2 TS muxings, causing the segment to be silent in Safari browser.

12/17/2019

2.36.0

Added

  • Support Image Overlay for live encodings. The specified image will replace the ingested video of the live stream for the defined time. Audio will be muted.
  • Support concatenation for different resolution inputs
    • Specify AspectMode when adding a concatenated input stream
  • Support for custom XML in PlayReady DRM WRM header added for DASH (playReady -> additionalInformation)
  • Trimming for Dolby Vision mezzanine files is now supported
  • H.265/HEVC 2pass and 3pass encoding jobs will process up to 10% faster
  • Enhanced detection of open GOP files to correctly handle them.

Fixed

  • CC to WebVTT conversion was uncompliant after one hour when appendOptionalZeroHour was set to true
  • There has been a potential stalling condition related to big output configurations (e.g. when excessive thumbnails creation was enabled).
  • HDR-10 encoding jobs with big output configurations where likely to stall in previous versions.
  • TS descriptor for E-AC-3 audio codecs is now correctly set

Known Issues

  • Per-Title encodings only work with GCS, S3, Generic S3, Akamai NetStorage or Azure Blob output.
  • Progressive MP4 with CBR encodings might have incorrect HRD buffer signaling.
  • S3 role-based output for segmented muxings: No upload verification available
  • Minimal chance of producing SAMPLE-AES encrypted TS segments with non-monotonically increasing timestamps for encodings with at least 2 TS muxings, causing the segment to be silent in Safari browser.

12/3/2019

2.35.1

Fixed

  • Improved analyzing of input for fail-fast in case erroneous DTS and unsupported open-GOP files

Known Issues

  • Per-Title encodings only work with GCS, S3, Generic S3, Akamai NetStorage or Azure Blob output.
  • Progressive MP4 with CBR encodings might have incorrect HRD buffer signaling.
  • S3 role-based output for segmented muxings: No upload verification available
  • Minimal chance of producing SAMPLE-AES encrypted TS segments with non-monotonically increasing timestamps for encodings with at least 2 TS muxings, causing the segment to be silent in Safari browser.

12/3/2019

2.35.0

Added

Fixed

  • Per-Title is now supported for Dolby Vision workflows.
  • In the concatenation workflow, if more than 10 inputs were provided, encoding produced incorrect output.

Known Issues

  • Per-Title encodings only work with GCS, S3, Generic S3, Akamai NetStorage or Azure Blob output.
  • Progressive MP4 with CBR encodings might have incorrect HRD buffer signaling.
  • S3 role-based output for segmented muxings: No upload verification available
  • Minimal chance of producing SAMPLE-AES encrypted TS segments with non-monotonically increasing timestamps for encodings with at least 2 TS muxings, causing the segment to be silent in Safari browser.
