Release Candidate 1 v1.12.0 Torrent Duck

Release v1.11.0 Smew Duck

2021-09-27 v1.11.0 "Smew Duck"
  This maintenance release adds support for VBR mode in VP9 rate control
  interface, new codec controls to get quantization parameters and loop filter
  levels, and includes several improvements to NEON and numerous bug fixes.

  - Upgrading:
    New codec control is added to get quantization parameters and loop filter
    levels.

    VBR mode is supported in VP9 rate control library.

  - Enhancement:
    Numerous improvements for Neon optimizations.
    Code clean-up and refactoring.
    Calculation of rd multiplier is changed with BDRATE gains.

  - Bug fixes:
    Fix to overflow on duration.
    Fix to several instances of -Wunused-but-set-variable.
    Fix to avoid chroma resampling for 420mpeg2 input.
    Fix to overflow in calc_iframe_target_size.

Release Candidate v1.11.0 Smew Duck

Release v1.10.0 Ruddy Duck

2021-03-09 v1.10.0 "Ruddy Duck"

  This maintenance release adds support for darwin20 and new codec controls, as
  well as numerous bug fixes.

  - Upgrading:

    New codec control is added to disable loopfilter for VP9.

    New encoder control is added to disable feature to increase Q on overshoot
    detection for CBR.

    Configure support for darwin20 is added.

    New codec control is added for VP9 rate control. The control ID of this
    interface is VP9E_SET_EXTERNAL_RATE_CONTROL. To make VP9 use a customized
    external rate control model, users will have to implement each callback
    function in vpx_rc_funcs_t and register them using libvpx API
    vpx_codec_control_() with the control ID.

  - Enhancement:

    Use -std=gnu++11 instead of -std=c++11 for c++ files.

  - Bug fixes:

    Override assembler with --as option of configure for MSVS.

    Fix several compilation issues with gcc 4.8.5.

    Fix to resetting rate control for temporal layers.

    Fix to the rate control stats of SVC example encoder when number of spatial
    layers is 1.

    Fix to reusing motion vectors from the base spatial layer in SVC.

    2 pass related flags removed from SVC example encoder.
