Compiles FFmpeg command line from passed arguments (executable path, options, inputs and outputs). ``inputs`` and ``outputs`` are dictionares containing inputs/outputs as keys and their respective options as values. One dictionary value (set of options) must be either a single space separated string, or a list or strings without spaces (i.e. each part of the option is a separate item of the list, the result of calling ``split()`` on the options string). If the value is a list, it cannot be mixed, i.e. cannot contain items with spaces. An exception are complex FFmpeg command lines that contain quotes: the quoted part must be one string, even if it contains spaces (see *Examples* for more info). For more info about FFmpeg command line format see `here `_. :param str executable: path to ffmpeg executable; by default the ``ffmpeg`` command will be searched for in the ``PATH``, but can be overridden with an absolute path to ``ffmpeg`` executable :param iterable global_options: global options passed to ``ffmpeg`` executable (e.g. ``-y``, ``-v`` etc.); can be specified either as a list/tuple/set of strings, or one space-separated string; by default no global options are passed :param dict inputs: a dictionary specifying one or more input arguments as keys with their corresponding options (either as a list of strings or a single space separated string) as values :param dict outputs: a dictionary specifying one or more output arguments as keys with their corresponding options (either as a list of strings or a single space separated string) as values T)add_input_optionN) executable_cmd _is_sequenceshlexsplit_merge_args_opts subprocess list2cmdlinecmdprocess)selfrglobal_optionsinputsoutputsnormalized_global_optionsoptr5D:\Projects\ConvertPro\env\Lib\site-packages\ffmpy.py__init__ s  zFFmpeg.__init__cCsd|jj|jS)Nz <{0!r} {1!r}>)format __class____name__r )rrrr__repr__<szFFmpeg.__repr__c Ksztj|jftj|||d||_Wnty.}z|jtjkr)td |j d}~ww|jj |d}|jj dkrJt |j|jj |d|d|S)aExecute FFmpeg command line. ``input_data`` can contain input for FFmpeg in case ``pipe`` protocol is used for input. ``stdout`` and ``stderr`` specify where to redirect the ``stdout`` and ``stderr`` of the process. By default no redirection is done, which means all output goes to running shell (this mode should normally only be used for debugging purposes). If FFmpeg ``pipe`` protocol is used for output, ``stdout`` must be redirected to a pipe by passing `subprocess.PIPE` as ``stdout`` argument. You can pass custom environment to ffmpeg process with ``env``. Returns a 2-tuple containing ``stdout`` and ``stderr`` of the process. If there was no redirection or if the output was redirected to e.g. `os.devnull`, the value returned will be a tuple of two `None` values, otherwise it will contain the actual ``stdout`` and ``stderr`` data returned by ffmpeg process.
