Enum CliScope 

#[non_exhaustive]
pub enum CliScope {
    Global,
    Input,
    Output,
    AfterOutput,
}

Where in the command an option was found (positional scoping: options apply to the next file on the command line).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Global

An option the support table classifies as global: it applies to the whole run wherever it appears (e.g. -y), so no file position is reported for it.

Input

Before -i: applies to the input file.

Output

After the input, before the output path: applies to the output file.

AfterOutput

After the output path: in ffmpeg grammar an option here would apply to a FOLLOWING output file, which the single-output subset does not have.
