Encoding REST API Services

• For AV1 encodings these presets are now available
  • VOD_QUALITY - Higher quality
  • VOD_STANDARD - Default quality and speed
  • VOD_SPEED - Faster encoding
• Added validations for time based trimming input streams: The encoding now fails fast if the (rounded) duration of all the time based trimming input streams is 0 or negative.
• The Manifest Generator V2 now supports generating SMOOTH manifests containing more than 1 encoding.

• Added support for Per-Title AV1 encodings to the Simple Encoding API.

• The H264 presets VOD_STANDARD and VOD_QUALITY now use the H264 profile 'MAIN' instead of 'HIGH'. See documentation here.

• Manifest Generator V2 is now available for single-encoding SMOOTH manifests by specifying manifestGenerator=V2 in the SMOOTH Start-Manifest Request. The minimum encoder version for that feature is 1.108.0. Differences to the LEGACY generator include:
  • V2 now correctly sets the "QualityLevels" attribute in the StreamIndex elements to the count of QualityLevel elements present.
  • V2 now correctly sets the "Index" attribute in the QualityLevel elements by increasing the number with each element.

• Fixed info messages for GCE infratstructure creation.

• Cloud Region AWS_EU_NORTH_1 (Stockholm) is now available for encoder version 2.107.0 and newer.
• Several performance improvements to the HLS manifest generation via the HLS Manifest Start call. HLS manifest generation with many renditions is now up to 5 times faster.

• HLS Manifest generation failed when the encoding containted an MP3 Audio Muxing even if the HLS Manifest did not reference the MP3 Muxing.

• Several performance improvements to the DASH manifest generation via the Dash Manifest Start call. DASH manifest generation with many renditions is now up to 20 times faster.

• Updated the documentation for the daily statistics calls to make it clear that offset and limit parameters are not used.

• Added PTSAlignMode to fMP4 muxings. Setting it to ALIGN_ZERO_NEGATIVE_CTO will shift the first composition time offset (CTO) to 0. If B-frames are used, some CTOs will be negative. Therefore, TrackRun (trun) version 1 atoms are being used. This can only be set for H264 and H265 streams.

• Fixed a bug where Per-Title analysis with NextGuard watermarking and fractional framerates failed

• Placeholders in the output path can now be used with the Simple Encoding API: {uuid} or {asset} will be replaced either with a random UUID or with the name of the asset provided as input (for VIDEO or DEFAULT input type). More examples can be found here
• Interlaced video input to the Simple Encoding API will now be deinterlaced automatically.

A brand-new way to interact with our encoder - the Simple Encoding API

• With the Simple Encoding API you only need a single API call providing an input source and an output destination to start an encoding.
• You can find more information about the template and configuration possibilities here.
• This API is especially meant for everybody looking to quickly prepare videos for OTT streaming (DASH and HLS) following industry best practices. Sensible defaults, no micro-optimizations.
• Under the hood, this API is utilizing the same high performance encoding engine used by leading media brands, automatically creating the best ladder for each asset with our award-winning per-title.

• HLS Default Manifests use the language of the audio stream language (stream.metadata.language) if defined.

• Fixed a potential encoding stall for HDR to SDR conversions with files below 10 seconds.
• Fixed a bug where Prewarmed Encoder Pools in combination with Cloud Connect could lead to very slow encodings.

• Fixed a bug for the VoD and live statistics endpoints with time ranges where offsets led to an empty result.
