Encoding Encoder Releases

Latest Releases

Date

Version

Beta

3/2/2021

2.66.0

Fixed

  • Fixed an issue in Per-Title algorithm where an input with extremely low spatial and temporal complexity lead to failures.

Known Issues

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

2/23/2021

2.65.0

Added

  • On encodings that fail with licensing errors, the corresponding retry hint is set in the status response.

Fixed

  • Verification for NexGuard FileMarker Watermarking that input source FPS and configured keyFrameInterval/GOP corresponds to the requirements if the frame rate is not configured in the codec configuration.
  • Improved stability for Azure Cloud Storage
  • Fixed a bug that lead to failed encodings when applying long trimmings to perTitle encodings.
  • Fixed a bug for HEVC outputs in combination with fMP4 and FairPlay DRM where the parameter sets were incorrectly placed in the samples, causing playback issues in native MacOs devices.

Known Issues

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

2/9/2021

2.64.1

Fixed

Known Issues

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

2/9/2021

2.64.0

Added

  • Packed Audio supports segment naming template.

Fixed

  • When using empty sourceChannels in audio-mix input stream the input channels will be automatically mapped to the same output channels by default
  • Fixed a color conversion issue for Dolby Vision Encodes from Prores inputs where the internal color conversion from YUV to RGB was performed using BT709 where is should be BT2020.
  • Fixed a rare bug for HEVC encodes with progressive mp4 output where the parameter sets were not included in the output file correctly.

Known Issues

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

2/2/2021

2.63.0

Added

  • Securing your assets with Nagra NexGuard FileMarker A/B Watermarking is now available
  • Segmented WebVTT subtitles now can be configured to either omit or include WebVTT cue identifiers (included by default). Please note that the following restrictions apply:
    • SRT to WebVTT conversion workflow does not support cue identifiers as of now. Therefore it needs to be set to OMIT_IDENTIFIERS.
    • Cue identifier can not be configured for non-segmented WebVTT outputs.

Fixed

  • Fixed a bug where WebVtt Encodings failed with subtitles using FileInputStreamType SRT. The bug occurred only in combination with video input files, that have negative DTS timestamps at the beginning.
  • Fixed a bug that audio streams were not sent to the LiveMediaIngest endpoint.
  • For a few audio-only input files, the analyze phase might have failed as the duration could not be parsed
  • Fixed a possible situation where duplicate DTS values are present in segmented TS outputs in case that the H264 codec is used with a b-pyramid setting of either 'normal' or 'strict'.

Known Issues

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

Stable

1/26/2021

2.62.0

Added

  • Support for PackedAudioMuxing: Allows to create Packed Audio Segments containing encoded audio samples and ID3 tags that are packed together with minimal framing and no per-sample timestamps.
  • Added configuration of PCR interval for Broadcast TS.

Changed

  • Optimized turnaround times for Dolby Vision 2-pass and 3-pass encoding jobs up to 40%

Fixed

  • The set encryptionMethod is now used when using CENC encryption without Fairplay
  • Fixed an issue where trying to detect the subtitle format from the data stream failed and caused an encoding error, by trying to deduce the subtitle format from the file extension in this case. If both fails, the encoding will still fail.
  • Fixed a bug for ProgressiveMovMuxings which caused the output of muxings, that contained more than one audio stream, to only contain the first audio stream.
  • Fixed a bug where the Encoding failed if more than one video representation has been configured in combination with subtitles with FileInputStreamType SRT.
  • Fixed a rarely occurring race condition during encoding start-up that was preventing our service to use all the computing nodes.
  • The i-frame-playlist manifests for fmp4 encodings have been corrected
  • Downloads might have stalled with HTTP(S) inputs and file paths containing non-alphanumeric characters
  • Fixed an issue with failed encodings when using channelLayout in audio mix input stream
  • Fixed a potential issue where interlaced MOV files led to encoding errors because they were detected as interlaced Mp4 has been fixed.
  • Bugfix where HEVC encodes with Level 4.1 set were falsely set to level 4.0.

Known Issues

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

1/11/2021

2.61.1

Added

Fixed

  • Fixed an issue with the encoder not being able to extract cdp CEA captions
  • Fixed that VP9 3-Pass encodings could fail in case that the target bitrate of single segments was close to the codec-level's maximum bitrate and QMIN was set to a low value.
  • In rare conditions, an encoding might have stalled in the Analysis phase and go to error after 1 hour
  • If the ROTATION stream condition is used and the rotation property is not present in the input file, a default of 0 will be used.
  • Input subtitle text files with exotic character encoding, BOM markers, exotic end of lines or trailing white-spaces are now sanitized before being decoded.
  • A bug mispredicting the character encoding of a UTF-8 subtitle input file with many languages (not a real-life use case, but useful for testing) has been fixed.

Known Issues

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

12/16/2020

2.60.1

Fixed

  • Fixed a bug that potentially caused out of sync issues of video and audio for h.264 encodings with CBR and BroadcastTS muxings

Known Issues

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

12/15/2020

2.60.0

Added

Fixed

  • SRT subtitle burn-in subtitle feature was corrupting memory when the target pixel format was different from the one from the source video. This has been fixed now.
  • A potential problem has been fixed for 3-pass encodings, where key-frame-boundaries with segment-cut was enabled.

Known Issues

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

12/1/2020

2.59.0

Changed

Fixed

  • Fixed a bug where an encoding might finish successfully but not the whole content was encoded when using Concatenation Input-Streams combined with trimming, if at the concatenation boundaries the cumulated duration is an exact multiple of the segment length.
  • Quality improvement for HRD CBR compliant progressive outputs.
  • Set the correct content-type when using Progressive MP4. If it's an audio-only stream it will be set to audio/mp4, if it's video only or contains both, it will be set to video/mp4
  • Fixed invalid outputs in Enhanced Deinterlace Filter when both Field and Frame stream filters are requested in the same encoding.
  • Fixed a crash that was triggered by encoding with the same Enhanced Deinterlace Filter mode but different FPS. Example: 50 FPS Field and 25 FPS Field is now working.

Known Issues

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