Encoding Encoder Releases

Latest Releases

Date

Version

Beta

7/27/2021

2.86.0

Added

  • Manifest generator V2 is now generally available and supports all manifest features of our API.
    • It can be used by directly setting manifest IDs in the start encoding request and setting manifestGenerator to V2.
    • We are therefore deprecating the manifest generator V2_BETA option and will remove it from our API SDKs in release v2.89.0.
    • For more information see our tutorial here.

Fixed

  • The RFC6381 codec label (e.g. "avc1.64001F") for CMAF muxings is now correctly set in DASH and HLS manifests.
  • If the same input source is created twice and used twice in an encoding, we are no longer downloading the input file twice.
  • Fixed a bug with handling HEVC inputs with open GOPs which caused encodings to fail.
  • RASL (Random Access Skip Leading) frames are now correctly removed from the very first GOP of the HEVC inputs.
  • Fixed SegmentTemplate timescale in DASH manifests potentially being set to a wrong value when using variable framerate inputs, causing clients to request a non-existent video segment at the end.

Known Issues

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

7/20/2021

2.85.0

Added

  • Added support for Thumbnail Letter and Pillarboxing. Supported aspect modes: CROP, PAD, STRETCH. More Details described in the API Calls:

Fixed

  • Muxing an H265 video and Dolby Atmos audio stream into a single MP4 container is now supported.
  • We are now more resilient against Azure connection issues when checking if input files exist.
  • An issue was fixed where VP9 3-PASS encodings could fail if the target bitrate of a single segment was too close to the codec-level's maximum bitrate.

Known Issues

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

7/13/2021

2.84.0

Added

Fixed

  • Color conversion to the following color primaries: bt709, smpte170m, smpte240m, bt2020. As a result, color primaries conversion from smpte432 to bt2020 is not red-shifted anymore.
  • Long running HEVC encodes with 3-pass and cutree setting enabled failing in rare cases.
  • For DASH manifests, containing Dolby audio renditions, the codecs attribute is not set on AdaptationSet level anymore but only on the Representation level. This also fixes a rare case of duplicate entries in the codecs attribute which could have led to device compatibility issues.

Known Issues

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

7/15/2021

2.83.1

Added

  • Dolby Digital and Dolby Digital Plus codec configurations are now available as replacement for AC3 and EAC3.
    • We are therefore deprecating AC3 and EAC3 as the two new codec configurations are producing output, which conforms to Dolby's high certification standards.
    • Our multi-codec example now uses Dolby Digital instead of AC3.
    • For more information see our tutorial here.
  • Sprite generation no longer requires both width and height to be set, as long as one of the two values is configured, the other one is automatically computed based on the aspect ratio of the video.
  • Thumbnail creation has been extended to allow the same options with regards to height and width as sprite generation.

Fixed

  • Improved internal stall-detection to prevent additional edge cases. These edge cases previously lead to stalls resulting in unexpectedly long running encodings.
  • Dolby Atmos encodings previously failed if there was an additional unused audio stream along the video stream. This has been fixed.
  • Encodings with input concatenation with inputs that have different fps have occasionally stalled. This was fixed.

Known Issues

  • S3 role-based output for segmented muxings: No upload verification available.
  • AdaptationSets in DASH manifests could contain the same codec multiple times in the codecs attribute, when the manifest contains a Dolby Digital, Dolby Digital Plus or a Dolby Atmos rendition.

7/6/2021

2.83.0

Added

This version is automatically mapped to 2.83.1 because of a bug in Dolby Vision processing for segmented output.

Stable

7/15/2021

2.82.1

Added

  • targetDurationRoundingMode property on HLS manifest, which defines the rounding mode for the target duration (normal or upward rounding) for manifests generated during the encoding.

Fixed

  • Live encoding restarts could have taken several minutes or lead to an encoding error
  • Improved internal stall-detection to prevent occurences of unexpectedly long running encodings due to stalls.

Known Issues

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

6/29/2021

2.82.0

Added

This version is automatically mapped to 2.82.1 because of a bug in Dolby Vision processing for segmented output.

6/22/2021

2.81.0

Added

  • Ability to handle ephemeral infrastructure errors working with genuine S3 has been improved
  • Support for additional output resolutions when encoding from a 3840x2160 Dolby Vision mezzanine file: 480p, 320p, 240p and 160p

Fixed

  • Fixed a bug where Sprites with lots of thumbnails (because of a long video file or a low duration value) could lead to a failing or stalling encoding.

Known Issues

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

6/15/2021

2.80.0

Fixed

  • The stability of live-encodings subtitle streams using Zixi as ingest has been improved.
  • A bug has been fixed for live encodings where the segment duration included fractional seconds. In those cases, the segment duration was erroneously rounded-down to the next full second.
  • Encoding jobs with progressive muxings and DolbyVision output did not handle letterboxing correctly, possibly resulting in the DolbyVision filter being incorrectly applied.
  • When using S3 Role-based Input without an externalId to download bigger files could have lead to a failed download if it took more than 15 minutes.

Known Issues

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

6/9/2021

2.79.1

Fixed

  • A bug has been fixed for live encodings where the segment duration included fractional seconds. In those cases the segment duration was erroneously rounded-down to the next full second.

Known Issues

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