v0.2.4

Added boolean property encore-settings.encoding.exit-on-error (default true) that will add ffmpeg flag -xerror (Stop and exit on error).
Added map property encore-settings.encoding.global-params (default empty map) for params to be added before other params.

v0.2.3

New feature: Dialogue enhancement
AudioEncode can now enhance dialogue by compressing background channels using signal from front center channel of input. This is done with the Ffmpeg filter sidechaincompress. If the input is stereo, a front center is produced using the Ffmpeg filter dialoguenhance before applying sidechaincompress. Dialogue enhancement can optionally be combined with an audioMixPreset to further lift the center channel and/or lower the background channels.
To enable this feature, simply add dialogueEnhancement.enabled: true to an AudioEncode in a profile like this:

  - type: AudioEncode
    bitrate: 128k
    suffix: _STEREO_DE
    dialogueEnhancement:
      enabled: true

Dialogue enhancement can be customized further using properties (listed are the default values):

 - type: AudioEncode
   bitrate: 128k
   suffix: _STEREO_DE
   dialogueEnhancement:
     enabled: true
     sidechainCompress:
       ratio: 8
       threshold: 0.012
       release: 1000.0
       attack: 100.0
     dialogueEnhanceStereo:
       enabled: true
       original: 1
       enhance: 1
       voice: 2  

v0.2.2

• Use input params when performing analysis.
• Fix thumbnail map issue #23 as suggested by @grusell
• Prevent thumbnails from in some cases being detected as video.
• Add joinSegmentParams to Profile to be applied when joining segments.
• When running tests, redis is started in a docker container.

Spring spel expressions in profile

Added support for spring spel expressions in profiles.
See https://docs.spring.io/spring-framework/reference/core/expressions.html.
Profiles are parsed as spel expression templates with EncoreJob as root object.
Added field profileParams to EncoreJob to be used in profile templates.

v0.2.0

Introducing Encore Instant - Chunked based encoding in Encore

NEW FEATURES

• Encore now supports chunked based encoding - allowing for a potential massive increase in transcoding speed (which is mostly limited by storage I/O) by encoding parts of a video in parallel across several instances / machines.
• Set segmentLength (in seconds) in encoreJob to activate chunked encoding, it should be a multiple of the target GOP. Encore will then transcode segments of that length in parallel across the cluster of servers. Requires 'encore-settings.sharedWorkDir' pointing to dir accessible to all encore instances for intermediate storage of transcoded segments.
• Startup time has been greatly improved by support for native compilation using graalvm (tested with graalvm community edition 17.0.8).

KNOWN LIMITATIONS

• Encore Instant currently relies heavily on ffmpeg's input seek. This means that input files of a format that ffmpeg can't properly input seek through (just about everything that is not I-Frame only codecs/flavours) wont work out of the box!
• Encore Instant is only suitable for 1-pass transcodes, usually x264 / x265 CRF or Mezzanine files.
• Encore Instant does not allow thumbnail output

BREAKING CHANGES

• code base has been split into three parts:
• encore-web: A drop in replacement for the old encore artifact. Exposing rest endpoints.
• encore-worker: Artifact suitable for running single jobs from the work queue, e.g as Kubernetes jobs triggered by KEDA.
• encore-common: code shared by encore-web and encore-worker
