Encoding Encoder Releases

Latest Releases

Date

Version

11/25/2020

2.56.2

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.

Known Issues

  • S3 role-based output for segmented muxings: No upload verification available.
  • Per-Title encodings only work with GCS, S3, Generic S3, Akamai NetStorage or Azure Blob output.
    This information can be found in this FAQ from now on: Which output options are supported when using per-title?

2.56.1

Fixed

  • A memory leak related to the frame rate change logic has been fixed, which possibly caused encodings to fail, when changing from a higher to a lower frame rate.

Known Issues

  • S3 role-based output for segmented muxings: No upload verification available.
  • Per-Title encodings only work with GCS, S3, Generic S3, Akamai NetStorage or Azure Blob output.

Added

  • A new Enhanced Deinterlace Filter is now available.

  • Added support for SRT live input streams with a bitrate >= 40Mbps.

Fixed

  • Fixed the cache-control header for manifest uploads in both Live and Vod workflows to contain the correct max-age:value instead of max-age=value string
  • Fixed a bug for the usage of Display Aspect Ratio (DAR) on VP9 and AV1 encodes if muxed with ProgressiveWebmMuxing (manifestType=NONE).

9/22/2020

2.54.0

Changed

  • Improved download speed of input files in Azure cloud up to 150%

  • Support for 3-pass encodings in Azure
  • Improved encoding speed of high bitrate J2K inputs in Azure
  • Support for XDCAM output with the following new codecs / muxings:

Fixed

  • Issue when vbv parameters are set in 3-pass algorithm with the last segment quality was fixed
  • Fixed some combinations of color config with VP9 codec which lead to failures
  • Fixed an error that led to failed 3-pass encodings in the cloud region AWS_EU_WEST_2

  • Improved stability and speed of encodings with longer segment lengths and/or very high input-bitrate in GCE

Fixed

  • A possibly re-connect issue has been fixed for the live use-case when a timestamp rotation occurs in the following order Video, Subtitle, and Audio and the Subtitle packet was following an Audio packet.
  • Bugfix for Conform filter together with trimming for video streams.

  • The issue with stalling encodings for inputs with reordered frames in Mov was improved. We will fail instead of stalling.

Fixed

  • Bugfix for Dolby Vision and trimming. The output could be missing some frames at the end of the encode.
