Parameters ---------- filename Name of any video or audio file, like ``video.mp4`` or ``sound.wav`` etc. size Size (width,height) in pixels of the output video. fps_input Frames per second of the input audio (given by the AudioClip being written down). nbytes : int, optional Number of bytes per sample. Default is 2 (16-bit audio). nchannels : int, optional Number of audio channels. Default is 2 (stereo). codec : str, optional The codec to use for the output. Default is ``libfdk_aac``. bitrate: A string indicating the bitrate of the final video. Only relevant for codecs which accept a bitrate. input_video : str, optional Path to an input video file. If provided, the audio will be muxed with this video. If not provided, the output will be audio-only. logfile : file-like object or None, optional A file object where FFMPEG logs will be written. If None, logs are suppressed. ffmpeg_params : list of str, optional Additional FFMPEG command-line parameters to customize the output.
