Encoding Encoder Releases

Latest Releases

Date

Version

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.

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.

11/17/2020

2.58.0

Added

  • Customers using their own Azure account can now opt-in, so that all SSH communication comes from one specific IP address. This enables a more rigid network security policy where only one IP is allowlisted for SSH connections.

Fixed

  • Fixed a bug in the fMP4 muxing of audio segments where the last segment contained 1 single audio frame.
  • Combination of Audio Mix and Audio Merge with StreamInput are now handled properly.
  • The fMP4 muxing-information endpoint now correctly returns "codec": "aac" for muxings with AAC audio codec.
  • Fixed a bug for input files that were creating an empty segment and therefore the encoding failed.
  • 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.
  • Fixed an issue, where DASH and HLS manifest creation failed for SINGLE_PASS and TWO_PASS encodings, which had PRORES or JPEG2000 inputs.

Known Issues

  • S3 role-based output for segmented muxings: No upload verification available.
  • An encoding might finish successfully with not the whole content 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.

11/3/2020

2.57.0

Added

  • Added handling of SMPTE timecode with three flavours - NON_DROP_FRAME, DROP_FRAME, and AUTO.
  • Private ACLs are now taken into account for manifests and live encodings

Fixed

  • DAR values are now correctly set in all progressive webm outputs for VP8/VP9.
  • Encodings failing at the output validation step, with init.mp4 file missing, have been fixed.

Known Issues

  • S3 role-based output for segmented muxings: No upload verification available.
  • A memory leak related to the frame rate change logic might cause encodings to get stuck or fail, when changing from a higher to a lower frame rate.
  • An encoding might finish successfully with not the whole content 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.

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?

2.56.0

Added

  • A new Enhanced Deinterlace Filter is now available.
  • Azure Connect: Encoding on customer Azure infrastructure is now available for VoD and live encodings.
  • Added support for SRT live input streams with a bitrate >= 40Mbps.
  • Enabled full VBV buffer conformance for progressive h.264 CBR outputs.

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).
  • When using I-Frame playlists with fmp4, the #EXT-X-TARGETDURATION and #EXTINF attributes are now correctly set based on the segment length
  • Fixed stream playback issue caused by inconsistent first DTS in shorter segments.
  • In certain use cases, using keyframes in conjunction with concatenation workflow lead to failed encoding. This has been fixed.
  • Live encodings did not work when using AWS or GCP connect and being opt-in so that all SSH communication comes from one specific IP address
  • Fixed an issue with default manifests for per-title that potentially lead to failed encodings.

2.55.0

Changed

  • Improved download and upload speed for Azure significantly.

  • Fixed a bug where the I-frame playlist was missing in the HLS output.
  • Live streams are now working when using GCP Connect or AWS Connect
  • Fixed a bug for Per-title encodings where specific sample and display aspect ratio combinations caused incorrect width or height of the output.

Known Issues

  • Per-Title encodings only work with GCS, S3, Generic S3, Akamai NetStorage or Azure Blob output.
  • Progressive MP4 with CBR encodings might have incorrect HRD buffer signaling.
  • S3 role-based output for segmented muxings: No upload verification available.
  • A memory leak related to the frame rate change logic might cause encodings to get stuck or fail, when changing from a higher to a lower frame rate.
