2.198.0

Released 2024-05-28

Fixed

2.196.0

Released 2024-04-30

  • Encoding name is now part of the Triggered event messages (for both LIVE and VOD).

Fixed

  • Fixed wrong VIDEO-RANGE attribute in HLS manifests created with manifest generator V2 for encodings performing a conversion from Dolby Vision to SDR.

Known Issues

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

2.195.0

Released 2024-04-16

Added

  • Invalid or unspecified color properties (color space, color range, color transfer, color primaries) would trigger a warning message.

Fixed

  • Transcoding from a long duration input with Dolby E could result in a failed encoding. This has been fixed.

Known Issues

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

2.194.0

Released 2024-04-03

Fixed

  • Fixed an issue where encodings using progressive mov muxings would fail when the output file contained special characters (e.g. spaces).
  • Improved scheduling of 8k Encodings, which were previously getting stalled sometimes.
  • Encodings with fractional segment lengths, using keyframe feature, could sometimes result in missing subtitle segments. This has been fixed now.

Known Issues

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

2.193.1

Released 2024-03-20

Added

  • VOD Encoder now supports transcoding Dolby E (as input) to Dolby Digital/Dolby Digital Plus (as output). Current support comes with following limitations:
    • Dolby E must be in 2 individual mono PCM channels in the input. One stereo channel in the input is not supported.
    • Only the first program can be transcoded
    • Programs with more than 6 channels are not supported.
      Any other usage of the API could result in incorrect output. If you intend to use Dolby E as input, please contact support.

Fixed

  • On setting handleVariableInputFps option to true, for some specific contents (where the number of consecutive B-Frames suddenly increased after a few hundred frames), the output was longer than the input. This has been fixed now.

Known Issues

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

2.192.0

Released 2024-03-12

Added

Known Issues

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

2.191.0

Released 2024-02-28

Added

  • Support for variable segment durations in fMp4 IFramePlaylist for HLS manifests created with manifest generator V2.

Changed

  • Upgraded Zixi Edge Compute (ZEC) to v16.11 for the Zixi Input for Live Encoding.

Fixed

  • For the manifest generator V2, the HLS version in fMp4 IFramePlaylist is now set to the same version as the HLS media manifest. Before, the HLS version of the IFramePlaylist was always 4, which caused problems for features that are not supported with HLS version 4.
  • A regression introduced in 2.175.0 was producing darker HLG output when using HLG signalling, used for backward-compatible HLG. Fixed in the current version.

Known Issues

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

2.190.0

Released 2024-02-06

Fixed

  • In case the audio track is much shorter than the video and RESYNC_AT_START_AND_END is selected in the StartEncodingRequest, the encoding is not slowing down anymore.

Known Issues

  • S3 role-based output for segmented muxings: No upload verification available.
  • Using HLG signalling, used for backward-compatible HLG, could result in darker output. Please use 2.191.0 or more recent version.

2.189.0

Released 2024-01-31

Fixed

  • A faulty initial input connection on a reconnect could block the stream from writing output segments and regenerating itself. This has been fixed by forcing a reconnect if corrupt metadata was probed.

Known Issues

  • S3 role-based output for segmented muxings: No upload verification available.
  • Using HLG signalling, used for backward-compatible HLG, could result in darker output. Please use 2.191.0 or more recent version.

2.188.0

Released 2024-01-23

Fixed

  • Fixed a regression introduced in 2.178.0 where an encoding may stall if a progressive MP4 muxing is configured where the output file extension is not ".mp4".

Known Issues

  • S3 role-based output for segmented muxings: No upload verification available.
  • Using HLG signalling, used for backward-compatible HLG, could result in darker output. Please use 2.191.0 or more recent version.

2.187.0

Released 2024-01-12

Added

  • Added support for AV1 with fMP4 in HLS manifests. FairPlay is also supported for this combination.

Changed

  • All progressive and fragmented MP4 muxings with an HEVC stream now have the codec tag name hvc1 (Apple recommendation) due to reported playback issues on Apple devices and the Quicktime player in the case of the codec tag name being hev1. Consequently, the codec tag names of HEVC streams in progressive MP4 muxings have been changed from hev1 to hvc1 in the following two cases:
    • When down-converting Dolby Vision to HDR10 or SDR
    • When the muxing contains a Dolby Atmos stream

Known Issues

  • S3 role-based output for segmented muxings: No upload verification available.
  • Encoding may stall with this version if a progressive MP4 muxing is configured where the output file extension is not ".mp4". Please use 2.188.0 or more recent version.
  • Using HLG signalling, used for backward-compatible HLG, could result in darker output. Please use 2.191.0 or more recent version.

2.186.0

Released 2024-01-09

Changed

  • The Frame-rate change logic has been improved. This implies that starting with this version every Frame-rate conversion will result in constant output segment length behaviour.
    The old behaviour where in case of fractional frame rate changes from e.g. 23.976 fps to 24.0 fps the output segment length in frames for 4 seconds segments was alternating between 96 and 97 frames is removed.
    The new rate change behaviour introduces a new fail fast error if the encoding configuration is not compliant. Read more about the scenarios that will result in this fail-fast error here.

Fixed

  • Encodings started using an AV1 codec configuration without specifying a bitrate will now fail to be started as it eventually resulted in a transcoding error.
  • Different trimming configurations for multiple audio streams were not applied correctly. This has been fixed.
  • Perform interlaced-aware scaling from interlaced input to interlaced output.
  • Improved output quality of Dolby Vision encodes at lower bitrates.

Known Issues

  • S3 role-based output for segmented muxings: No upload verification available.
  • Encoding may stall with this version if a progressive MP4 muxing is configured where the output file extension is not ".mp4". Please use 2.188.0 or more recent version.
  • Using HLG signalling, used for backward-compatible HLG, could result in darker output. Please use 2.191.0 or more recent version.

2.185.0

Released 2023-12-12
Added

Fixed

  • For JPEG2000 4K input with exactly 1 output rendition (1080p or higher) resulted in failed encodings. This has been fixed now.
  • Fixed encodings with Dolby Vision JPEG2000 inputs that failed with the error "Color conversion between YUV formats where only the color range changes is not supported". The error was triggered by an unsuccessful detection of the input color properties.

Known Issues

  • S3 role-based output for segmented muxings: No upload verification available.
  • Encoding may stall with this version if a progressive MP4 muxing is configured where the output file extension is not ".mp4". Please use 2.188.0 or more recent version.

2.164.0

Released 2023-05-03

Added

  • autoLevelSetup: property for video configurations (h264, h265, av1, vp9) to enable/disable the automatic calculation of level, maximum bitrate, and buffer size based on the lowest level that satisfies maximum property values for picture resolution, frame rate, and bitrate. In the case the target level is set explicitly, the maximum bitrate and buffer size are calculated based on the defined level. The autoLevelSetup is enabled by default and is automatically disabled if the maximum bitrate or buffer size is set.

Fixed

  • PerTitle Algorithm was sometimes losing a configured FIXED_RESOLUTION_AND_BITRATE when the configuration contained two FIXED_RESOLUTION_AND_BITRATE with the same resolution.

  • Corrected an issue which lead to Nielsen audio watermarking with multiple output video renditions to not be correctly applied under certain conditions.

Known Issues
