2.95.0

Released 2021-10-04

Added

With this release we've improved the encoding capabilities with regards to HDR conversions for H265 output. From now on we support

  • Dolby Vision to HDR10
  • Dolby Vision to SDR
  • HDR10 to HLG
  • HLG to HDR10
  • SDR to HDR10
  • SDR to HLG

The encoder detects the applicable conversion based on the input and the configured output color settings. To make it easier to correctly configure the output we have added preset configurations for the different dynamic range formats. These can be configured on the H265 resource via the setting dynamicRangeFormat.

Dolby Vision input can be configured with a Dolby Vision input stream

Fixed

  • Fixed a bug for H264 and H265 where the specified chroma location was not signaled correctly in the output bitstream.
  • Fixed a bug with CustomTags inside HLS audio manifests to be inserted at given KeyFrame positions when there is audio and video encoding. The tags were inserted occasionally a few segments before.

Known Issues

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

2.94.0

Released 2021-09-28

Added

  • Support for setting duration=null for Time-based Trimming to indicate that the whole stream should be used (considering offset). offset=null will be defaulted to zero now. We also fixed and issue when settingduration=0 which lead to different results for video and audio. Setting duration=0 will now lead to 0 frames for video and audio.

Fixed

  • Inputs with J2K or ProRes codec could have lead to oversaturated output when configured with bt709 and 1080p output.
  • Fixed an issue that affected some MOV inputs with an edts (EditListBox) atom. The duration of the edit list entry was not considered and therefore also the media data, that should have been discarded, was present in the output.

Known Issues

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

2.93.0

Released 2021-09-21

Fixed

Known Issues

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

  • In DASH manifests generated with ManifestGenerator V2 the AdaptationSet@id attributes were set to UUIDs which caused some players to fail because this property should be an unsigned int.
  • Fixed a bug for the manifestGenerator V2 in combination with DtsPassThroughAudioCodecConfigurations which caused encodings with VOD DASH manifests to fail and VOD HLS manifests to have an incorrect targetDuration.
  • When using ACLs to provide access to an S3 bucket from another account, the GetBucketLocation query could have failed, even though the permissions were set correctly which caused the encoding to fail

Known Issues

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

2.89.1

Released 2021-07-15

Fixed

  • Fixed the default_sample_duration of the init mp4 file for audio codecs with CMAF muxing. This fixes playback issues with DASH and HLS streams.
  • Fixed failing audio-only encodings when using concatenation with input files that include a video stream.
  • Fixed a bug with H264 picture timing trimming. If the start timing is before the first keyframe of the input, the start timing is now set to the timing of the first keyframe.
  • Fixed a bug which could lead to failed encodings when converting colorspace to BT709.
  • Fixed encodings failing when applying both trimming and conform filter with Dolby Digital and Dolby Digital Plus audio codecs.

2.87.0

Released 2021-08-03

Added

  • Added a new AudioVideoSyncMode RESYNC_AT_START_AND_END to the StartEncodingRequest. This mode pads audio streams with silence, if the audio streams are shorter than the video stream. This prevents DASH clients trying to download non-existent audio segments, if the mediaPresentationDuration is longer than the duration of the audio stream. This new mode is now also the default value.

Fixed

  • When running a live encoding with HLS manifests having a liveEdgeOffset close to the segmentLength, the manifest could have stopped updating after a couple of minutes, although segments are still written correctly

Known Issues

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

2.86.0

Released 2021-07-27

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.

Known Issues

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

2.84.0

Released 2021-07-13

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.

2.83.1

Released 2021-07-15

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.
