simulate: Do not download the video files.
- format: Video format code.
+ format: Video format code. See options.py for more information.
format_limit: Highest quality format to try.
outtmpl: Template for output names.
restrictfilenames: Do not allow "&" and spaces in file names
nooverwrites: Prevent overwriting files.
playliststart: Playlist item to start at.
playlistend: Playlist item to end at.
+ playlistreverse: Download playlist items in reverse order.
matchtitle: Download only matching titles.
rejecttitle: Reject downloads for matching titles.
logger: Log messages to a logging.Logger instance.

+ postprocessors: A list of dictionaries, each with an entry
+ * key: The name of the postprocessor. See
+ youtube_dl/postprocessor/__init__.py for a list.
+ as well as any further keyword arguments for the
+ postprocessor.
+ progress_hooks: A list of functions that get called on download
+ progress, with a dictionary with the entries
+ * filename: The final filename
+ * status: One of "downloading" and "finished"
+
+ The dict may also have some of the following entries:
+
+ * downloaded_bytes: Bytes on disk
+ * total_bytes: Size of the whole file, None if unknown
+ * tmpfilename: The filename we're currently writing to
+ * eta: The estimated time in seconds, None if unknown
+ * speed: The download speed in bytes/second, None if
+ unknown
+
+ Progress hooks are guaranteed to be called at least once
+ (with status "finished") if the download is successful.
