Raw

decoder Version 0.3.2

  • Dependency bumps

decoder Version 0.3.1

  • Rework y4m decoder to support stdin and other Read types

decoder Version 0.2.1

  • Fixes to ffmpeg decoder frame accuracy
  • Migrate to forked ffmpeg crate that is maintained

decoder Version 0.2.0

  • Add Vapoursynth decoder, available with vapoursynth cargo feature

decoder Version 0.1.10

  • Fix a bug where certain codecs may not return the final frame

decoder Version 0.1.9

  • Include libdav1d with ffmpeg_build feature
  • Add YUVJ support

Version 0.9.0

  • Bump dependencies, including v_frame to 0.3
  • Minor fixes

Version 0.8.2

  • Export Frame from the decoders crate as well
  • Bump dependencies

Version 0.8.1

  • [Breaking] Remove the FrameInfo struct and use v_frame::Frame directly
  • Migrate to edition 2021
  • Upgrade clap to 3.x
  • Upgrade ffmpeg-next to 5.x

Version 0.7.2

  • Add a new GUI version of the av-metrics-tool
  • Bump some dependencies

Version 0.7.1

  • Add ffmpeg decoding support; this is optional and currently requires building from source
  • Fix a math overflow on 32-bit for MSSSIM
  • Publish a new av_metrics_decoder crate, to use the y4m and ffmpeg decoders independently. These are re-exported through av-metrics, so the av-metrics interface is unchanged.
  • Add progress indicator
  • Remove internal unwraps (enables cleaner exiting, especially when used as a crate)
  • Improve error messages

Version 0.7.0

  • [CLI Feature] Support multiple file comparison
  • [CLI Feature] Add Markdown output
  • [CLI Feature] Add CSV output

Version 0.6.0

  • [Breaking] Simplify the Decoder trait
  • [Breaking] Require Send + Sync on the Decoder trait
  • Many performance and multi-threading improvements

Version 0.5.1

  • Remove unneeded library specifiers that were previously needed by cargo-c

Version 0.5.0

  • Bump y4m dependency to 0.6

Version 0.4.0

  • Breaking Change: Use Frame, Pixel, etc. types from the v_frame crate, instead of rolling our own. This should improve interoperability with other crates.
  • Speed up y4m decoding.
  • Minor internal changes and dependency updates.

Version 0.3.0

  • Breaking Change: Remove the use_simd flag from the public API. This was intended only for development purposes, and isn't generally useful to end users. If you really want to disable SIMD, you can set the environment variable AV_METRICS_DISABLE_SIMD to any value.
  • Breaking Change: PSNR and APSNR have been split into separate result sets. This only impacts users of the API. The CLI output is identical.
  • New Feature: --metric flag allows the CLI tool to output only one metric at a time, instead of all metrics.
  • New Feature: --json flag allows the CLI tool to output the results as JSON. This is primarily useful if you want to use the output in some other script or as data on a web page.
  • 25% speed improvement in CIEDE2000 with AVX2.

Version 0.2.1

  • Fix a bug where CIEDE2000 could report Infinity
  • Performance improvements to PSNR-HSV metric

Version 0.2.0

  • Add a binary for running metrics on y4m files (and other future formats)
    • This binary can be installed from the av-metrics-tool crate.
  • Breaking change: Decoder<T> is changed to Decoder and has a new method, get_bit_depth added. This allows us to dynamically dispatch to the correct version of a metric based on the bit depth, without the compiler getting in our way.
  • Add a workspace for managing the library and binary independently.

Version 0.1.0

  • Initial release
