Functions
@spec duration(binary() | format_map()) :: float() | :no_duration | {:error, :no_such_file}
Get the duration in seconds, as a float.
If no duration (e.g., a still image), returns :no_duration.
If the file does not exist, returns { :error, :no_such_file }
@spec format(binary()) :: {:ok, format_map()} | {:error, :invalid_file} | {:error, :no_such_file}

If the file does not exist, returns {:error, :no_such_file}.
If the file is a non media file, returns {:error, :invalid_file}.
@spec format_names(binary() | format_map()) :: {:ok, [binary()]} | {:error, :invalid_file} | {:error, :no_such_file}
Get a list of formats for the file.
If the file does not exist, returns {:error, :no_such_file}.
If the file is a non media file, returns {:error, :invalid_file}.
@spec streams(binary()) :: {:ok, streams_list()} | {:error, :invalid_file} | {:error, :no_such_file}
Get a list a of streams from the file.
