By default, the tool can only decode y4m files. Both files must match in resolution, bit depth, and color sampling.

Alternate input formats can be supported by enabling FFMpeg support.Due to limitations, this currently has to be enabled at compile time.

In the crate, this can be enabled with the feature "ffmpeg-decode".In the binary, this can be enabled with the feature "ffmpeg".
