Encoding Encoder Releases

Latest Releases

Date

Version

10/8/2019

2.29.1

Fixed

Known Issues

  • Per-Title encodings only work with GCS, S3, Generic S3 or Akamai NetStorage output
  • Progressive MP4 with CBR encodings might have incorrect HRD buffer signaling
  • S3 role-based output for segmented muxings: No upload verification available

10/8/2019

2.29.0

Added

  • Added S3 role-based output for segmented muxings.
  • Added support for segmented WebVTT for the HLS manifest.
  • Improved encoding speed for high bitrate files.

Fixed

  • Fixed one bug that caused stalled encodings that occurred sometimes on very high bitrate files.

Known Issues

  • Per-Title encodings only work with GCS, S3, Generic S3 or Akamai NetStorage output
  • Progressive MP4 with CBR encodings might have incorrect HRD buffer signaling
  • S3 role-based output for segmented muxings: No upload verification available

Beta

9/25/2019

2.28.0

Added

  • Added Conform filter which allows for small changes of the video frame rate where the playback speed of video as well as audio will be adapted instead of frame interpolation.

Fixed

  • Many consecutive timestamp discontinuity events in a live stream do not result in audio/video sync issues anymore
  • Insertable content now works for AC-3 audio streams in the input
  • Adding keyframes with encodingMode THREE_PASS does not result in an error anymore
  • HEVC video streams can now be muxed to segmented TS
  • HEVC coding delay will now be correctly signaled in fMP4 muxings

Known Issues

  • Per-Title encodings only work with GCS, S3, Generic S3 or Akamai NetStorage output
  • Progressive MP4 with CBR encodings might have incorrect HRD buffer signaling

9/10/2019

2.27.0

Added

  • Added dynamic scaling of watermarks with new properties width and height
  • Added option to exclude region for WebVTT conversions (ignoreRegion)
  • Added option to auto detect interlaced content when using deinterlace filter (autoEnable)
  • Add cutoffFrequency for AAC, AC3, EAC3

Fixed

  • If more then one insertable content are scheduled consecutively, this is not leading to audio/video sync issues anymore.
  • Improved stability for long running live streams.
  • Akamai MSL4 with CMAF output works as expected again
  • Fixed encoding to E-AC3 for cases where the last segment would be very short

Known Issues

  • Per-Title encodings only work with GCS, S3, Generic S3 or Akamai NetStorage output
  • Progressive MP4 with CBR encodings might have incorrect HRD buffer signaling
  • Adding keyframes with encodingMode THREE_PASS does result in an error

Stable

9/4/2019

2.26.1

Fixed

  • Improved efficiency during encoding setup when using Per-Title encodings

Known Issues

  • Per-Title encodings only work with GCS, S3, Generic S3 or Akamai NetStorage output
  • Progressive MP4 with CBR encodings might have incorrect HRD buffer signaling
  • If more then one insertable content are scheduled consecutively, this could lead to audio/video sync issues when playing the insertable content. The normal live feed is not affected.
  • Support for Akamai MSL CMAF output is broken

8/27/2019

2.26.0

Added

  • Fallback from multipart to regular S3 upload when using s3 servers that do not support multipart uploads
  • Further J2k decoding improvements with another speedup of about 50%
  • Improved startup stability when using Zixi live input

Fixed

  • Fixed rounding error in frame rate change logic. Now exactly every second frame will be dropped when down converting to half of the origianl frame rate.
  • HE-AAC will hit the correct target bitrate now for progressive outputs as well
  • Fixed audio/video sync issues on HE-AAC progressive outputs

Known Issues

  • Per-Title encodings only work with GCS, S3, Generic S3 or Akamai NetStorage output
  • Progressive MP4 with CBR encodings might have incorrect HRD buffer signaling
  • If more then one insertable content are scheduled consecutively, this could lead to audio/video sync issues when playing the insertable content. The normal live feed is not affected.
  • Support for Akamai MSL CMAF output is broken

8/23/2019

2.25.1

Fixed

  • Fixed copying of some codec configuration settings from Per-Title templates to Per-Title results
  • Fixed HLS manifest update issue for live encodings

Known Issues

  • Per-Title encodings only work with GCS, S3, Generic S3 or Akamai NetStorage output
  • Progressive MP4 with CBR encodings might have incorrect HRD buffer signaling
  • If more then one insertable content are scheduled consecutively, this could lead to audio/video sync issues when playing the insertable content. The normal live feed is not affected.
  • Support for Akamai MSL CMAF output is broken

8/13/2019

2.25.0

Added

  • Added Live Encoding Events to provide feedback in case an error occurs during scheduling of insertable content
  • Doubled the decoding speed for J2K inputs
  • Live encodings are now more resilient to upload failures to cloud storage for audio segments

Known Issues

  • Per-Title encodings only work with GCS, S3, Generic S3 or Akamai NetStorage output
  • Progressive MP4 with CBR encodings might have incorrect HRD buffer signaling
  • If more then one insertable content are scheduled consecutively, this could lead to audio/video sync issues when playing the insertable content. The normal live feed is not affected.
  • Support for Akamai MSL CMAF output is broken

8/2/2019

2.24.1

Fixed

  • Revert to previous J2K decoder because of stability issues with certain input files
  • Fixed increased turnaround times for BroadcastTS muxings

Known Issues

  • Per-Title encodings only work with GCS, S3, Generic S3 or Akamai NetStorage output
  • Progressive MP4 with CBR encodings might have incorrect HRD buffer signaling
  • If more then one insertable content are scheduled consecutively, this could lead to audio/video sync issues when playing the insertable content. The normal live feed is not affected.
  • When scheduling insertable content and there are errors with the content to insert, there is currently only minimal error feedback.
  • Support for Akamai MSL CMAF output is broken

7/30/2019

2.24.0

Added

  • Added progress information for 2pass and 3pass analysis
  • Added insertable content for live streams to inject VoD files into the stream at scheduled times
  • Added the capability to add multiple CENC DRMs (FairPlay, Widevine, PlayReady) to HLS playlists

Fixed

  • Stability improvements for 3pass encoding, where an invalid internal state of the encoder led to a crash
  • Upload of segmented content to Generic S3 was failing in certain cases, e.g., with Scality

Known Issues

  • Per-Title encodings only work with GCS, S3, Generic S3 or Akamai NetStorage output
  • Broadcast TS muxing workflows suffer from increased turnaround times during the muxing stage
  • Progressive MP4 with CBR encodings might have incorrect HRD buffer signaling
  • If more then one insertable content are scheduled consecutively, this could lead to audio/video sync issues when playing the insertable content. The normal live feed is not affected.
  • When scheduling insertable content and there are errors with the content to insert, there is currently only minimal error feedback.
  • Support for Akamai MSL CMAF output is broken
