The following parameters are not used by YoutubeDL itself, they are used by
- the FileDownloader:
+ the downloader (see youtube_dl/downloader/common.py):
nopart, updatetime, buffersize, ratelimit, min_filesize, max_filesize, test,
- noresizebuffer, retries, continuedl, noprogress, consoletitle
+ noresizebuffer, retries, continuedl, noprogress, consoletitle,
+ xattr_set_filesize, external_downloader_args, hls_use_mpegts,
+ http_chunk_size.
+
+ The following options are used by the post processors:
+ prefer_ffmpeg: If False, use avconv instead of ffmpeg if both are available,
+ otherwise prefer ffmpeg.
+ ffmpeg_location: Location of the ffmpeg/avconv binary; either the path
+ to the binary or its containing directory.
+ postprocessor_args: A list of additional command-line arguments for the
+ postprocessor.
+
+ The following options are used by the Youtube extractor:
+ youtube_include_dash_manifest: If True (default), DASH manifests and related
