Encoder 2.0.0 - 2.49.0

2.49.0

Released 2020-07-14

Added

For video encodings a display aspect ratio (DAR) for the output can be specified. If the DAR does not match with the width and height, then the sample aspect ratio (SAR) will be adjusted accordingly.

Fixed

Fixed an issue where PAR was not correctly handled when using Per-Title
Fixed an issue where Per-Title encoding does not work with input files that have high bitrates

Known Issues

Per-Title encodings only work with GCS or S3 output
3pass encodings might suffer from a stall up to 10 minutes

Fixed an issue where the trimming could be off by a couple of frames when using timecode
Restarts of live encoding is now up to 5x faster

Known Issues

Per-Title encodings only work with GCS or S3 output
Per-Title encoding fails with input files that have a high bitrate

2.2.0

Released 2018-10-22

Added

Per-Title analysis step is now 4x faster
Improved writing of live HLS manifest to be more resilient
Added new applied settings to the stream that are patched with the width and height used for encoding

Known Issues

Per-Title encoding fails with input files that have a high bitrate

2.1.0

Released 2018-10-16

Added

Return PAR in stream input analysis
Improved error message when a file on S3 cannot be downloaded
Enable HLG signaling options for HEVC
Support for vbv codec settings for Per-Title

Fixed

Fixed an issue where an encoding might stall at the very end when using a lot of renditions
Fixed IDR placement for HEVC

Known Issues

Per-Title encodings only work with GCS or S3 output

2.0.0

Released 2018-10-09

Added

Per Title Encoding
AV1 speed improvements by 40%. That means it's twice as fast as the reference implementation, 20 times slower than HEVC/VP9 and 40 times slower than H.264
Enhanced 2-pass and 3-pass encoding
Support de-multiplexed A/V input files
Support 2-Pass for live encoding
Added Keyframe settings to VP8/VP9
Added muxing information for Broadcast TS

Changed

Breaking Change: When adding a stream, the property decodingErrorMode is set to DUPLICATE_FRAMES per default
Breaking Change: When starting an encoding, the property encodingMode is set to TWO_PASS per default
Breaking Change: When starting an encoding, the property trimming -> ignoreDurationIfInputTooShort is set to true per default
Breaking Change: When starting an encoding, the property handleVariableInputFps is set to true per default
Breaking Change: When starting an encoding, the property tweaks -> audioVideoSyncMode is set to RESYNC_AT_START per default

Fixed

Fixed an upload bug that may occur when uploading Progressive MP4 files to Azure
Fixed an issue where the encoding may fail when using a small trimming duration

Known Issues

Per-Title encodings only work with GCS or S3 output
