22 # DESCRIPTION
23 **youtube-dl** is a small command-line program to download videos from
24 YouTube.com and a few more sites. It requires the Python interpreter, version
25 2.6, 2.7, or 3.3+, and it is not platform specific. It should work on
26 your Unix box, on Windows or on Mac OS X. It is released to the public domain,
27 which means you can modify it, redistribute it or use it however you like.
28
29 # OPTIONS
30 -h, --help print this help text and exit
31 --version print program version and exit
32 -U, --update update this program to latest version. Make
33 sure that you have sufficient permissions
34 (run with sudo if needed)
35 -i, --ignore-errors continue on download errors, for example to
36 skip unavailable videos in a playlist
37 --abort-on-error Abort downloading of further videos (in the
38 playlist or the command line) if an error
39 occurs
40 --dump-user-agent display the current browser identification
41 --user-agent UA specify a custom user agent
42 --referer REF specify a custom referer, use if the video
43 access is restricted to one domain
44 --add-header FIELD:VALUE specify a custom HTTP header and its value,
45 separated by a colon ':'. You can use this
46 option multiple times
47 --list-extractors List all supported extractors and the URLs
48 they would handle
49 --extractor-descriptions Output descriptions of all supported
50 extractors
51 --proxy URL Use the specified HTTP/HTTPS proxy. Pass in
52 an empty string (--proxy "") for direct
53 connection
54 --no-check-certificate Suppress HTTPS certificate validation.
55 --prefer-insecure Use an unencrypted connection to retrieve
56 information about the video. (Currently
57 supported only for YouTube)
58 --cache-dir DIR Location in the filesystem where youtube-dl
59 can store some downloaded information
60 permanently. By default $XDG_CACHE_HOME
61 /youtube-dl or ~/.cache/youtube-dl . At the
62 moment, only YouTube player files (for
63 videos with obfuscated signatures) are
64 cached, but that may change.
65 --no-cache-dir Disable filesystem caching
66 --socket-timeout None Time to wait before giving up, in seconds
67 --bidi-workaround Work around terminals that lack
68 bidirectional text support. Requires bidiv

70 --default-search PREFIX Use this prefix for unqualified URLs. For
71 example "gvsearch2:" downloads two videos
72 from google videos for youtube-dl "large
73 apple". Use the value "auto" to let
74 youtube-dl guess. The default value "error"
75 just throws an error.
76 --ignore-config Do not read configuration files. When given
77 in the global configuration file /etc
78 /youtube-dl.conf: do not read the user
79 configuration in ~/.config/youtube-dl.conf

275
276 # CONFIGURATION
277
278 You can configure youtube-dl by placing default arguments (such as `--extract-audio --no-mtime` to always extract the audio and not copy the mtime) into `/etc/youtube-dl.conf` and/or `~/.config/youtube-dl/config`. On Windows, the configuration file locations are `%APPDATA%\youtube-dl\config.txt` and `C:\Users\<Yourname>\youtube-dl.conf`.
279
280 # OUTPUT TEMPLATE
281
282 The `-o` option allows users to indicate a template for the output file names. The basic usage is not to set any template arguments when downloading a single file, like in `youtube-dl -o funny_video.flv "http://some/video"`. However, it may contain special sequences that will be replaced when downloading each video. The special sequences have the format `%(NAME)s`. To clarify, that is a percent symbol followed by a name in parenthesis, followed by a lowercase S. Allowed names are:
283
284 - `id`: The sequence will be replaced by the video identifier.
285 - `url`: The sequence will be replaced by the video URL.
286 - `uploader`: The sequence will be replaced by the nickname of the person who uploaded the video.
287 - `upload_date`: The sequence will be replaced by the upload date in YYYYMMDD format.
288 - `title`: The sequence will be replaced by the video title.
289 - `ext`: The sequence will be replaced by the appropriate extension (like flv or mp4).
290 - `epoch`: The sequence will be replaced by the Unix epoch when creating the file.
291 - `autonumber`: The sequence will be replaced by a five-digit number that will be increased with each download, starting at zero.
292 - `playlist`: The name or the id of the playlist that contains the video.
293 - `playlist_index`: The index of the video in the playlist, a five-digit number.
294
295 The current default template is `%(title)s-%(id)s.%(ext)s`.
296
297 In some cases, you don't want special characters such as 中, spaces, or &, such as when transferring the downloaded filename to a Windows system or the filename through an 8bit-unsafe channel. In these cases, add the `--restrict-filenames` flag to get a shorter title:
298
299 $ youtube-dl --get-filename -o "%(title)s.%(ext)s" BaW_jenozKc
300 youtube-dl test video ''_ä↭𝕐.mp4 # All kinds of weird characters
301 $ youtube-dl --get-filename -o "%(title)s.%(ext)s" BaW_jenozKc --restrict-filenames
302 youtube-dl_test_video_.mp4 # A simple file name
303
304 # VIDEO SELECTION
305
306 Videos can be filtered by their upload date using the options `--date`, `--datebefore` or `--dateafter`, they accept dates in two formats:
307
308 - Absolute dates: Dates in the format `YYYYMMDD`.
309 - Relative dates: Dates in the format `(now|today)[+-][0-9](day|week|month|year)(s)?`
310
311 Examples:
312
313 # Download only the videos uploaded in the last 6 months
314 $ youtube-dl --dateafter now-6months
315
316 # Download only the videos uploaded on January 1, 1970
317 $ youtube-dl --date 19700101
318
319 $ # will only download the videos uploaded in the 200x decade
320 $ youtube-dl --dateafter 20000101 --datebefore 20091231
321
322 # FAQ
323
324 ### Can you please put the -b option back?
325
326 Most people asking this question are not aware that youtube-dl now defaults to downloading the highest available quality as reported by YouTube, which will be 1080p or 720p in some cases, so you no longer need the `-b` option. For some specific videos, maybe YouTube does not report them to be available in a specific high quality format you're interested in. In that case, simply request it with the `-f` option and youtube-dl will try to download it.
327
328 ### I get HTTP error 402 when trying to download a video. What's this?
329
330 Apparently YouTube requires you to pass a CAPTCHA test if you download too much. We're [considering to provide a way to let you solve the CAPTCHA](https://github.com/rg3/youtube-dl/issues/154), but at the moment, your best course of action is pointing a webbrowser to the youtube URL, solving the CAPTCHA, and restart youtube-dl.
331
332 ### I have downloaded a video but how can I play it?
333
334 Once the video is fully downloaded, use any video player, such as [vlc](http://www.videolan.org) or [mplayer](http://www.mplayerhq.hu/).
335
336 ### The links provided by youtube-dl -g are not working anymore
337
338 The URLs youtube-dl outputs require the downloader to have the correct cookies. Use the `--cookies` option to write the required cookies into a file, and advise your downloader to read cookies from that file. Some sites also require a common user agent to be used, use `--dump-user-agent` to see the one in use by youtube-dl.
339
340 ### ERROR: no fmt_url_map or conn information found in video info
341
342 youtube has switched to a new video info format in July 2011 which is not supported by old versions of youtube-dl. You can update youtube-dl with `sudo youtube-dl --update`.
343
344 ### ERROR: unable to download video ###
345
346 youtube requires an additional signature since September 2012 which is not supported by old versions of youtube-dl. You can update youtube-dl with `sudo youtube-dl --update`.
347
348 ### SyntaxError: Non-ASCII character ###
349
350 The error
351
352 File "youtube-dl", line 2
353 SyntaxError: Non-ASCII character '\x93' ...
354
355 means you're using an outdated version of Python. Please update to Python 2.6 or 2.7.
356
357 ### What is this binary file? Where has the code gone?
358
359 Since June 2012 (#342) youtube-dl is packed as an executable zipfile, simply unzip it (might need renaming to `youtube-dl.zip` first on some systems) or clone the git repository, as laid out above. If you modify the code, you can run it by executing the `__main__.py` file. To recompile the executable, run `make youtube-dl`.
360
361 ### The exe throws a *Runtime error from Visual C++*
362
363 To run the exe you need to install first the [Microsoft Visual C++ 2008 Redistributable Package](http://www.microsoft.com/en-us/download/details.aspx?id=29).
364
365 # DEVELOPER INSTRUCTIONS
366
367 Most users do not need to build youtube-dl and can [download the builds](http://rg3.github.io/youtube-dl/download.html) or get them from their distribution.
368
369 To run youtube-dl as a developer, you don't need to build anything either. Simply execute
370
371 python -m youtube_dl
372
373 To run the test, simply invoke your favorite test runner, or execute a test file directly; any of the following work:
374
375 python -m unittest discover
376 python test/test_download.py
377 nosetests
378
379 If you want to create a build of youtube-dl yourself, you'll need
380
381 * python
382 * make
383 * pandoc
384 * zip
385 * nosetests
386
387 ### Adding support for a new site
388
389 If you want to add support for a new site, you can follow this quick list (assuming your service is called `yourextractor`):
390
391 1. [Fork this repository](https://github.com/rg3/youtube-dl/fork)
392 2. Check out the source code with `git clone git@github.com:YOUR_GITHUB_USERNAME/youtube-dl.git`
393 3. Start a new git branch with `cd youtube-dl; git checkout -b yourextractor`
394 4. Start with this simple template and save it to `youtube_dl/extractor/yourextractor.py`:
395
396 # coding: utf-8
397 from __future__ import unicode_literals
398
399 import re
400
401 from .common import InfoExtractor
402
403
404 class YourExtractorIE(InfoExtractor):
405 _VALID_URL = r'https?://(?:www\.)?yourextractor\.com/watch/(?P<id>[0-9]+)'
406 _TEST = {
407 'url': 'http://yourextractor.com/watch/42',
408 'md5': 'TODO: md5 sum of the first 10KiB of the video file',
409 'info_dict': {
410 'id': '42',
411 'ext': 'mp4',
412 'title': 'Video title goes here',
413 # TODO more properties, either as:
414 # * A value
415 # * MD5 checksum; start the string with md5:
416 # * A regular expression; start the string with re:
417 # * Any Python type (for example int or float)
418 }
419 }
420
421 def _real_extract(self, url):
422 mobj = re.match(self._VALID_URL, url)
423 video_id = mobj.group('id')
424
425 # TODO more code goes here, for example ...
426 webpage = self._download_webpage(url, video_id)
427 title = self._html_search_regex(r'<h1>(.*?)</h1>', webpage, 'title')
428
429 return {
430 'id': video_id,
431 'title': title,
432 # TODO more properties (see youtube_dl/extractor/common.py)
433 }
434
435
436 5. Add an import in [`youtube_dl/extractor/__init__.py`](https://github.com/rg3/youtube-dl/blob/master/youtube_dl/extractor/__init__.py).
437 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.
438 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.
439 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).
440 9. When the tests pass, [add](https://www.kernel.org/pub/software/scm/git/docs/git-add.html) the new files and [commit](https://www.kernel.org/pub/software/scm/git/docs/git-commit.html) them and [push](https://www.kernel.org/pub/software/scm/git/docs/git-push.html) the result, like this:
441
442 $ git add youtube_dl/extractor/__init__.py
443 $ git add youtube_dl/extractor/yourextractor.py
444 $ git commit -m '[yourextractor] Add new extractor'
445 $ git push origin yourextractor
446
447 10. Finally, [create a pull request](https://help.github.com/articles/creating-a-pull-request). We'll then review and merge it.
448
449 In any case, thank you very much for your contributions!

451 # BUGS
452
453 Bugs and suggestions should be reported at: <https://github.com/rg3/youtube-dl/issues> . Unless you were prompted so or there is another pertinent reason (e.g. GitHub fails to accept the bug report), please do not send bug reports via personal email.
454
455 Please include the full output of the command when run with `--verbose`. The output (including the first lines) contain important debugging information. Issues without the full output are often not reproducible and therefore do not get solved in short order, if ever.
456
457 For discussions, join us in the irc channel #youtube-dl on freenode.
458
459 When you submit a request, please re-read it once to avoid a couple of mistakes (you can and should use this as a checklist):
460
461 ### Is the description of the issue itself sufficient?
462
463 We often get issue reports that we cannot really decipher. While in most cases we eventually get the required information after asking back multiple times, this poses an unnecessary drain on our resources. Many contributors, including myself, are also not native speakers, so we may misread some parts.
464
465 So please elaborate on what feature you are requesting, or what bug you want to be fixed. Make sure that it's obvious
466
467 - What the problem is
468 - How it could be fixed
469 - How your proposed solution would look like
470
471 If your report is shorter than two lines, it is almost certainly missing some of these, which makes it hard for us to respond to it. We're often too polite to close the issue outright, but the missing info makes misinterpretation likely. As a commiter myself, I often get frustrated by these issues, since the only possible way for me to move forward on them is to ask for clarification over and over.
472
473 For bug reports, this means that your report should contain the *complete* output of youtube-dl when called with the -v flag. The error message you get for (most) bugs even says so, but you would not believe how many of our bug reports do not contain this information.
474
475 Site support requests **must contain an example URL**. An example URL is a URL you might want to download, like http://www.youtube.com/watch?v=BaW_jenozKc . There should be an obvious video present. Except under very special circumstances, the main page of a video service (e.g. http://www.youtube.com/ ) is *not* an example URL.
476
477 ### Are you using the latest version?
478
479 Before reporting any issue, type youtube-dl -U. This should report that you're up-to-date. About 20% of the reports we receive are already fixed, but people are using outdated versions. This goes for feature requests as well.
480
481 ### Is the issue already documented?
482
483 Make sure that someone has not already opened the issue you're trying to open. Search at the top of the window or at https://github.com/rg3/youtube-dl/search?type=Issues . If there is an issue, feel free to write something along the lines of "This affects me as well, with version 2015.01.01. Here is some more information on the issue: ...". While some issues may be old, a new post into them often spurs rapid activity.
484
485 ### Why are existing options not enough?
486
487 Before requesting a new feature, please have a quick peek at [the list of supported options](https://github.com/rg3/youtube-dl/blob/master/README.md#synopsis). Many feature requests are for features that actually exist already! Please, absolutely do show off your work in the issue report and detail how the existing similar options do *not* solve your problem.
488
489 ### Is there enough context in your bug report?
490
491 People want to solve problems, and often think they do us a favor by breaking down their larger problems (e.g. wanting to skip already downloaded files) to a specific request (e.g. requesting us to look whether the file exists before downloading the info page). However, what often happens is that they break down the problem into two steps: One simple, and one impossible (or extremely complicated one).
492
493 We are then presented with a very complicated request when the original problem could be solved far easier, e.g. by recording the downloaded video IDs in a separate file. To avoid this, you must include the greater context where it is non-obvious. In particular, every feature request that does not consist of adding support for a new site should contain a use case scenario that explains in what situation the missing feature would be useful.
494
495 ### Does the issue involve one problem, and one problem only?
496
497 Some of our users seem to think there is a limit of issues they can or should open. There is no limit of issues they can or should open. While it may seem appealing to be able to dump all your issues into one ticket, that means that someone who solves one of your issues cannot mark the issue as closed. Typically, reporting a bunch of issues leads to the ticket lingering since nobody wants to attack that behemoth, until someone mercifully splits the issue into multiple ones.
498
499 In particular, every site support request issue should only pertain to services at one site (generally under a common domain, but always using the same backend technology). Do not request support for vimeo user videos, Whitehouse podcasts, and Google Plus pages in the same issue. Also, make sure that you don't post bug reports alongside feature requests. As a rule of thumb, a feature request does not include outputs of youtube-dl that are not immediately related to the feature at hand. Do not post reports of a network error alongside the request for a new video service.
500
501 ### Is anyone going to need the feature?
502
503 Only post features that you (or an incapicated friend you can personally talk to) require. Do not post features because they seem like a good idea. If they are really useful, they will be requested by someone who requires them.
504
505 ### Is your question about youtube-dl?
506
507 It may sound strange, but some bug reports we receive are completely unrelated to youtube-dl and relate to a different or even the reporter's own application. Please make sure that you are actually using youtube-dl. If you are using a UI for youtube-dl, report the bug to the maintainer of the actual application providing the UI. On the other hand, if your UI for youtube-dl fails in some way you believe is related to youtube-dl, by all means, go ahead and report the bug.
