v0.4.2

• Update indicatif dependency to 0.17.

v0.4.1

• For -e libvpx-vp9 map --preset number to ffmpeg -cpu-used (0-5).
• When overriding with a ffmpeg encoder avoid setting b:a, movflags or ac if explicitly set via --enc.
• Add error output when using --enc-input with the default svt-av1 encoder.
• Add errors for --enc/--enc-input args that are already provided by existing args or inferred.

v0.4.0

• Add --encoder/-e encoder override.
  Any encoder ffmpeg supports
  and that may be controlled using -crf may be used.
• Add --enc $FFMPEG_ARG for providing arbitrary output options to the ffmpeg encoder invocation.
  These only work when overriding the encoder with -e.
  
  E.g. Set x265 params: -e libx265 --enc x265-params=lossless=1.
• Add --enc-input $FFMPEG_ARG for providing ffmpeg input file options, similar to --enc.
• --preset now supports also word presets like slow, veryfast for ffmpeg encoders like libx264.
• --preset is no longer required. Default svt-av1 --preset is now 8.
• Support setting keyint for -e encoders in a similar way as is done for av1.
• Add default vp9 & libaom-av1 -b:v 0 setting so constant quality crf based encoding works consistently.
• For -e libaom-av1 map --preset number to ffmpeg -cpu-used (0-8).
• For *_vaapi encoders map --crf to ffmpeg -qp as crf is not supported.
• Shell escape file name in "Encoding ..." output.

v0.3.4

• Shell escape file names when hinting commands.

v0.3.3

• Show more info when auto-encode fails to find a suitable crf.

v0.3.2

• Improve sample generation speed & frame duration accuracy.

v0.3.1

• Fix some cases where ffmpeg progress & VMAF score output parsing failed.
• Fix some edge cases where crf-search would succeed exceeding the specified --max-encoded-percent.

v0.3.0

• Select vmaf model model=version=vmaf_4k_v0.6.1 for videos larger than 2560x1440 if no other model is specified.
  This will raise VMAF scores for 4k videos that previously were getting harsher treatment from the 1k model.
• Add --vmaf-scale option which sets the video resolution scale to use in VMAF analysis.
  auto (default) auto scales based on model & resolution, none no scaling or custom WxH
  format, e.g. 1920x1080.
  • auto upscale 1728x972 & smaller to 1080p, preserving aspect, when using the default 1k VMAF model.
    This will reduce VMAF scores that previously were getting more generous treatment from the 1k model.
  • auto upscale 3456x1944 & smaller to 4k, preserving aspect, when using the 4k VMAF model.
• Add --downmix-to-stereo option, if enabled & the input streams use > 3 channels (dts 5.1 etc),
  downmix input audio streams to stereo.
• After encoding print per-stream sizes in addition to the file size & percent.
• Add predicted video stream percent reduction to auto-encode search progress bar after a successful search.
• Support non-video/audio/subtitle streams from input to output, e.g. attachments.
• When defaulting the output file don't use input extension if it is avi, y4m, ivf, use mp4 instead.
• Fix clearing crf-search progress bar output on error.
• Strip debug symbols in release builds by default which reduces binary size (requires rustc 1.59).

v0.2.0

• Add svt-av1 option --keyint FRAME-OR-DURATION argument supporting frame integer or duration string.
  E.g. --keyint=300 or --keyint=10s.
  Default keyint to 10s when input duration is over 3m.
• Add svt-av1 option --scd true|false argument enabling scene change detection.
  Default scd on when using default keyint & input duration is over 3m.
• Add --svt ARG for additional args, e.g. --svt mbr=2000 --svt film-grain=30.
• Add --vfilter ARG argument to apply a ffmpeg video filter (crop, scale etc) to the input before av1 encoding.
  E.g. --vfilter "scale=1280:-1,fps=24".
• Add --pix-format ARG argument supporting yuv420p10le (default) & yuv420p.
• Add vmaf configuration --vmaf ARG, e.g. --vmaf n_threads=8 --vmaf n_subsample=4.
• Rename vmaf command argument --reference (was --original).
• Add vmaf command --reference-vfilter argument, similar to --vfilter.
• Default vmaf n_threads to the number of logical CPUs.
• Add --temp-dir argument to specify storage of sample data.
  May also be set with env var AB_AV1_TEMP_DIR.
• Add --sample-every DURATION argument, default "12m".
• Remove 3 sample default, this is now calculated using --sample-every 12m default.
• Create samples concurrently while encoding to reduce io lags waiting to encode.
• crf-search re-use samples for crf analysis.
• Linux: vmaf use fifo to convert both reference & distorted to yuv which fixes vmaf accuracy in some cases.
• Support multiple audio & subtitle streams.
• Use 128k bitrate as a default for libopus audio.
• Remove --aq.
• Fail fast if ffmpeg cut samples are empty (< 1K).
• Handle input durations lower than the sample duration by using the whole input as a single sample.

v0.1.1

• Add command to generate bash,fish & zsh completions ab-av1 print-completions [SHELL].
