- 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
