Some keyword-arguments are handled specially, as shown below. Args: video_bitrate: parameter for ``-b:v``, e.g. ``video_bitrate=1000``. audio_bitrate: parameter for ``-b:a``, e.g. ``audio_bitrate=200``. format: alias for ``-f`` parameter, e.g. ``format='mp4'`` (equivalent to ``f='mp4'``). If multiple streams are provided, they are mapped to the same output. To tell ffmpeg to write to stdout, use ``pipe:`` as the filename.
