pub fn get_subtitle_format_err(
    extension: Option<&OsStr>,
    content: &[u8],

Expand description

Returns the subtitle format by the file extension and provided content.

Works exactly like get_subtitle_format, but instead of None a UnknownFileFormat will be returned (for simpler error handling).
