Encoding Encoder Releases

Latest Releases

Date

Version

4/12/2019

2.17.2

Fixed

  • For HEVC resolutions where width or height was not divisible by 8, the wrong width or height was written to the container format. This let to visual artifacts on the frame edges on some players.

Known Issues

  • Per-Title encodings only work with GCS, S3 or Akamai NetStorage output

Beta

4/11/2019

2.17.1

Fixed

  • When using segmentNamingTemplate for Live encodings, the resolved segmentNaming will be patched, so that it can be retrieved via API. This enables Live to VoD workflow for that use case. The patching also applies for initSegmentNameTemplate
  • Dash Manifests always had a value of 2 in AudioChannelConfiguration, also if the channel had a higher count (e.g. 6 for 5.1)
  • Allow for huge configurations with many streams, muxings and DRM configurations that failed before

Known Issues

  • Per-Title encodings only work with GCS, S3 or Akamai NetStorage output

4/10/2019

2.17.0

Added

  • Object detection for encodings, that uses our new machine learning technology
  • CMAF muxing for Live and VoD workflows with the ability to configure CMAF chunks
  • Enabled the combination HLS + fMP4 + Widevine for VoD workflows
  • Attribute availabilityStartTime of DASH manifests has millisecond precision now

Fixed

  • Re-enabled the combination fMP4 + Fairplay + H264
  • Encoding does not fail anymore, when thumbnail configuration is out-of-bounds
  • Improved decoding of DVCProHD source files to avoid video corruption at the bottom of the frame

Known Issues

  • Per-Title encodings only work with GCS, S3 or Akamai NetStorage output

3/28/2019

2.16.1

Fixed

  • Removed the occurence of blocking artifacts for dark scenes using HEVC 3pass introduced by using low bitrates

Known Issues

  • Per-Title encodings only work with GCS, S3 or Akamai NetStorage output

3/26/2019

2.16.0

Added

  • Auto detect audio sample rate for live inputs
  • Added option to specify the character encoding for Burn-In subtitles
  • Support concatenation for input files with differing audio channel layout

Fixed

  • Encoding jobs with multiple inputs and GOP sizes longer than the configured segment length where failing in previous versions.
  • Some decoding errors where not correctly propagated to the API.
  • Frame rate signaling in a DASH manifest was incorrect if FPS was not configured for a live stream.
  • MPEG-DASH SegmentTimeline will now playback without errors on Roku devices
  • Very short segments where given too much bitrate for 3pass encodings

Known Issues

  • Per-Title encodings only work with GCS, S3 or Akamai NetStorage output

3/19/2019

2.15.0

Added

  • Added listener mode for SRT
  • Added {rand_chars} placeholder for segmentNamingTemplate and initSegmentNameTemplate to generate a random character sequence. This is especially useful when restarting a live stream and having storage / CDN caching enabled.
  • Better handling of disconnects and reconnects for SRT streams

Fixed

  • Fixed an issue where the HLS manifest might get stalled during a live streaming when using CLOSED_CAPTION in the media resource along with AUDIO resource

Known Issues

  • Per-Title encodings only work with GCS, S3 or Akamai NetStorage output

3/15/2019

2.14.1

Added

  • Fixed distortion of applied watermarks in case the source content contains anamorphic pixels
  • Fixed Per-Title algorithm to work with multiple bitrate constraints for same resolution
  • Fixed Per-Title algorithm where the analysis would fail for large step sizes

Known Issues

  • Per-Title encodings only work with GCS, S3 or Akamai NetStorage output

3/12/2019

2.14.0

Added

  • Added support for SRT Live Input
  • Auto detect Frame Rate for live input
  • Improved VP9 turn-around times by up to 3x
  • VP9 rate-control improvements
  • Fixed VP9 with 3pass to hit the target bitrate
  • Fixed HEVC rate control to avoid quality drops after scenes following black frames
  • Be more robust to incorrect timestamps of audio and video input files

Known Issues

  • Per-Title encodings only work with GCS, S3 or Akamai NetStorage output

Stable

2/28/2019

2.13.0

Added

  • Support for UTC Timing and Accessability element in Live DASH manifests
  • Added EXT-X-PROGRAM-DATE-TIME for HLS Live playlists
  • Added support for HLS manifests with fMP4 muxing and CENC FairPlay DRM
  • Support of international characters for Burn-in subtitles

Fixed

  • Fixed an issue where the combination of more than one Audio Mix filter might result in an unexpected audio output
  • Fixed an issue where the thumbnail creation failed when a whitespace was in the input file
  • Fixed an issue where the combination of fMP4 muxing and HLSv3 TS muxing causes an invalid DASH manifest
  • Improved 3pass HEVC quality after a scene change in combination with Per-Title. In some cases blocking artifacts where visible for a few frames.
  • Fixed an issue where too many warning logs where recorded for JPEG 2000 encoded source assets. This was resulting in a failed encoding.

Known Issues

  • Per-Title encodings only work with GCS, S3 or Akamai NetStorage output
  • VP9 in combination with 3-pass does not hit the target bitrate, please use 2-pass instead

2/21/2019

2.12.3

Added

  • Enabled Live-to-VoD for Zixi ingest streams

Fixed

  • Fixed a bug where encodings could fail when trimming is applied in combination with long GOP sizes of the input file
  • Fixed decoding of JPEG2000 assets where our encoder detected a wrong source FPS
  • Improved turnaround time of 3pass encodes when doing lots of encodes in parallel

Known Issues

  • Per-Title encodings only work with GCS, S3 or Akamai NetStorage output
  • VP9 in combination with 3-pass does not hit the target bitrate, please use 2-pass instead
