Encoding Encoder Releases

• 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.

• 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.

• 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.

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

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

• 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.

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

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

• 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 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.

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

• 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.

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

• 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.

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

• Added support for SCTE-35. When running a live encoding, calling this endpoint will trigger the insertion of cue tags in the provided HLS manifests and ads will be inserted.
  Note: this is an experimental feature.

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

• Improved speed of h.264 encodings with short input files

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

• Encoding jobs with Dolby Vision output that have multiple progressive and/or multiple segmented muxings failed in previous versions. This is properly supported now.
• The RTMP live-input related error 'broken pipe' now leads to a reconnect-attempt, while previous versions failed immediately.
• Subtitle stream encoded with the webvtt format and uploaded to S3 did not have the right mimetype set. This has been fixed and the uploaded subtitle file's mimetype is now correctly set to "text/vtt".

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