Functions
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 }
Get the "format" map, containing general info for the specified file, such as number of streams, duration, file size, and more. If the file does not exist, returns { :error, :no_such_file }. If the file is a non media file, returns { :error, :invalid_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 }.
Get a list a of streams from 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 }.

duration(file_path)
Specs
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 }
format(file_path)
Specs
format(binary()) :: {:ok, format_map()} | {:error, :invalid_file} | {:error, :no_such_file}
Get the "format" map, containing general info for the specified file, such as number of streams, duration, file size, and more. If the file does not exist, returns { :error, :no_such_file }. If the file is a non media file, returns { :error, :invalid_file }.
format_names(file_path)
Specs
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 }.
streams(file_path)
Specs
streams(binary()) :: {:ok, streams_list()} | {:error, :invalid_file} | {:error, :no_such_file}
Get a list a of streams from 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 }.
