"Create a generator to write frames (bytes objects) into a video file.\n",
"\n",
"The frames are written by using the generator's `send()` method. Frames\n",
"can be anything that can be written to a file. Typically these are\n",

"\n",
" gen = write_frames(path, size)\n",
" gen.send(None) # seed the generator\n",

" gen.send(frame)\n",
" gen.close() # don't forget this\n",

"Parameters:\n",
" path (str): the filename to write to.\n",
" size (tuple): the width and height of the frames.\n",
" pix_fmt_in (str): the pixel format of incoming frames.\n",
" E.g. \"gray\", \"gray8a\", \"rgb24\", or \"rgba\". Default \"rgb24\".\n",
" pix_fmt_out (str): the pixel format to store frames. Default yuv420p\".\n",
" fps (float): The frames per second. Default 16.\n",
" quality (float): A measure for quality between 0 and 10. Default 5.\n",
" Ignored if bitrate is given.\n",
" bitrate (str): The bitrate, e.g. \"192k\". The defaults are pretty good.\n",
" codec (str): The codec. Default \"libx264\" for .mp4 (if available from\n",
" the ffmpeg executable) or \"msmpeg4\" for .wmv.\n",
" macro_block_size (int): You probably want to align the size of frames\n",
" to this value to avoid image resizing. Default 16. Can be set\n",
" to 1 to avoid block alignment, though this is not recommended.\n",
" ffmpeg_log_level (str): The ffmpeg logging level. Default \"warning\".\n",
" ffmpeg_timeout (float): Timeout in seconds to wait for ffmpeg process\n",
" to finish. Value of 0 or None will wait forever (default). The time that\n",
" ffmpeg needs depends on CPU speed, compression, and frame size.\n",
" input_params (list): Additional ffmpeg input command line parameters.\n",
" output_params (list): Additional ffmpeg output command line parameters.\n",
" audio_path (str): A input file path for encoding with an audio stream.\n",
" Default None, no audio.\n",
" audio_codec (str): The audio codec to use if audio_path is provided.\n",
" \"copy\" will try to use audio_path's audio codec without re-encoding.\n",
" Default None, but some formats must have certain codecs specified.\n",
