Add the following to your Cargo.toml

av-metrics = "0.3"

Then check out the API docs.

Downlad the latest binary from the Releases tab.

Pre-built binaries are coming soon. In the meantime, have the latest stable Rust installed and run the following:

cargo install av-metrics-tool

From any terminal, run the executable with your two video files as arguments:

➜ av-metrics-tool lossless.y4m lossy.y4m

You should receive output for all supported metrics:

APSNR - Y: 32.5450  U: 36.4087  V: 39.8244  Avg: 33.6995
