(default is 1024)
--no-resize-buffer do not automatically adjust the buffer
automatically resized from an initial value
of SIZE.
--playlist-reverse Download playlist videos in reverse order
+ --xattr-set-filesize (experimental) set file xattribute
+ ytdl.filesize with expected filesize
+ --external-downloader COMMAND (experimental) Use the specified external
+ downloader. Currently supports

## Filesystem Options:
-a, --batch-file FILE file containing URLs to download ('-' for
--write-info-json write video metadata to a .info.json file
--write-annotations write video annotations to a .annotation
file
- --write-thumbnail write thumbnail image to disk
--load-info FILE json file containing the video information
(created with the "--write-json" option)
--cookies FILE file to read cookies from and dump cookie
--no-cache-dir Disable filesystem caching
--rm-cache-dir Delete all filesystem cache files
+## Thumbnail images:
+ --write-thumbnail write thumbnail image to disk
+ --write-all-thumbnails write all thumbnail image formats to disk
+ --list-thumbnails Simulate and list all available thumbnail
+ formats
+
## Verbosity / Simulation Options:
-q, --quiet activates quiet mode
--no-warnings Ignore warnings
--bidi-workaround Work around terminals that lack
bidirectional text support. Requires bidiv
or fribidi executable in PATH
+ --sleep-interval SECONDS Number of seconds to sleep before each
+ download.
## Video Format Options:
-f, --format FORMAT video format code, specify the order of
by extension for the extensions aac, m4a,
mp3, mp4, ogg, wav, webm. You can also use
the special names "best", "bestvideo",
- "bestaudio", "worst". By default, youtube-
- dl will pick the best quality. Use commas
- to download multiple audio formats, such as
- -f
+ "bestaudio", "worst". You can filter the
+ video results by putting a condition in
+ brackets, as in -f "best[height=720]" (or
+ -f "[filesize>10M]"). This works for
+ filesize, height, width, tbr, abr, and vbr
+ and the comparisons <, <=, >, >=, =, != .
+ Formats for which the value is not known
+ are excluded unless you put a question mark
+ (?) after the operator. You can combine
+ format filters, so -f "[height <=?
+ 720][tbr>500]" selects up to 720p videos
+ (or videos where the height is not known)
+ with a bitrate of at least 500 KBit/s. By
+ default, youtube-dl will pick the best
+ quality. Use commas to download multiple
+ audio formats, such as -f
136/137/mp4/bestvideo,140/m4a/bestaudio.
You can merge the video and audio of two
formats into a single file using -f <video-
5. Add an import in [`youtube_dl/extractor/__init__.py`](https://github.com/rg3/youtube-dl/blob/master/youtube_dl/extractor/__init__.py).
6. Run `python test/test_download.py TestDownload.test_YourExtractor`. This *should fail* at first, but you can continually re-run it until you're done. If you decide to add more than one test, then rename ``_TEST`` to ``_TESTS`` and make it into a list of dictionaries. The tests will be then be named `TestDownload.test_YourExtractor`, `TestDownload.test_YourExtractor_1`, `TestDownload.test_YourExtractor_2`, etc.
7. Have a look at [`youtube_dl/common/extractor/common.py`](https://github.com/rg3/youtube-dl/blob/master/youtube_dl/extractor/common.py) for possible helper methods and a [detailed description of what your extractor should return](https://github.com/rg3/youtube-dl/blob/master/youtube_dl/extractor/common.py#L38). Add tests and code for as many as you want.
-8. If you can, check the code with [pyflakes](https://pypi.python.org/pypi/pyflakes) (a good idea) and [pep8](https://pypi.python.org/pypi/pep8) (optional, ignore E501).
+8. If you can, check the code with [flake8](https://pypi.python.org/pypi/flake8).
9. When the tests pass, [add](http://git-scm.com/docs/git-add) the new files and [commit](http://git-scm.com/docs/git-commit) them and [push](http://git-scm.com/docs/git-push) the result, like this:
