Slicer release 21102800

November 1st, 2021

Fixes:

  • Fix static luminance monitoring that converged on 1 or more fixed values when using nvenc encoder.

  • Fix muting and blank audio insertion on dolby subtracks.

  • Fix dolby stereo downmix routing from dolby decoder to dolby stereo encoder.

  • Fix slicing of WindowsMedia VOD file with 5.1 WMA Pro audio.

  • Use correct time base to calculate frame pts/dts/dur when multiple audio tracks with different sample rates are present.

  • Fix incorrect gain applied to AAC tracks when slicing with Dolby output option.

  • Fix UDP liveslicer ingest of 5.1 AAC when liveslicer config doesn’t specify PID’s.

Other changes:

  • Reduce slicer latency caused by unnecessarily long padding audio on the trailing edge of the slice.

  • Change interpretation of [[gain1, gain2]] from [[aac, dolby]] to [[stereo, surround]].

  • Take advantage of the render_608_buffer to aggregate CC updates.

  • Add -suppress_608_input (same as -no608), and -suppress_608_output options to slicer and liveslicer.

Prerequisites:

  • Due to the slicer being built on CentOS 7 it picks up a new library dependency on libnl-3.200, which is not included in the base install of Ubuntu 18.04. You may need to pre-install it: sudo apt install libnl-3-200

  • Nvidia driver 418 or later is required for HEVC 4K HDR/SDR.

  • Due to CentOS 6 reaching EOL in November 2020 this slicer release requires CentOS 7 or newer.
