  • A regression that was introduced in 2.164.0 leading to missing analysis details for streams in cases when pertitle and audio was configured.

  • Fixed an issue with VP9 encodings where it could happen that a level violation was triggered in the encoder for SINGLE_PASS encodings. This was fixed by disabling alternate reference frames for all VP8/VP9 SINGLE_PASS encodings.

  • Queueing time considerably reduced when using Pre-warmed Encoder Pools.

**Known Issues**

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



## 2.172.0

**Known Issues**

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



## 2.170.0

  • For Live Encodings, when using `AesEncryptionDrm` with a specified `keyFileUri`, the keyFile was not properly uploaded to the designated output. This has been fixed.

  • Improved resilience in case of intermittent infrastructure hiccups. If recovery is not possible, the encoding would eventually fail rather than stalling.

  • Improve s3 download speed in case the bucket location is not set for the encoding or can't be queried, which can be caused by a missing `s3:GetBucketLocation` permission.

**Added**

  • The behaviour of `isDefault` in hls manifest's mediainfo was changed. Setting a value of `isDefault = false` will now be flagged in manifests as `DEFAULT=NO` when using manifest V2.
