How do I download only new videos from a playlist?
For one, have a look at the list of supported sites. Note that it can
sometimes happen that the site changes its URL scheme (say, from
-http://example.com/video/1234567 to http://example.com/v/1234567 ) and
+https://example.com/video/1234567 to https://example.com/v/1234567 ) and
youtube-dl reports an URL of a service in that list as unsupported. In
that case, simply report a bug.
python test/test_download.py
nosetests
+See item 6 of new extractor tutorial for how to run extractor specific
+test cases.
+
If you want to create a build of youtube-dl yourself, you'll need
- python
1. Fork this repository
2. Check out the source code with:
- git clone git@github.com:YOUR_GITHUB_USERNAME/youtube-dl.git
+ git clone git@github.com:YOUR_GITHUB_USERNAME/youtube-dl.git
3. Start a new git branch with
- cd youtube-dl
- git checkout -b yourextractor
+ cd youtube-dl
+ git checkout -b yourextractor
4. Start with this simple template and save it to
youtube_dl/extractor/yourextractor.py:
class YourExtractorIE(InfoExtractor):
_VALID_URL = r'https?://(?:www\.)?yourextractor\.com/watch/(?P<id>[0-9]+)'
_TEST = {
- 'url': 'http://yourextractor.com/watch/42',
+ 'url': 'https://yourextractor.com/watch/42',
'md5': 'TODO: md5 sum of the first 10241 bytes of the video file (use --test)',
'info_dict': {
'id': '42',
_TEST to _TESTS and make it into a list of dictionaries. The tests
will then be named TestDownload.test_YourExtractor,
TestDownload.test_YourExtractor_1,
- TestDownload.test_YourExtractor_2, etc.
+ TestDownload.test_YourExtractor_2, etc. Note that tests with
+ only_matching key in test's dict are not counted in.
7. Have a look at youtube_dl/extractor/common.py for possible helper
methods and a detailed description of what your extractor should and
may return. Add tests and code for as many as you want.
8. Make sure your code follows youtube-dl coding conventions and check
- the code with flake8. Also make sure your code works under all
- Python versions claimed supported by youtube-dl, namely 2.6, 2.7,
- and 3.2+.
-9. When the tests pass, add the new files and commit them and push the
+ the code with flake8:
+
+ $ flake8 youtube_dl/extractor/yourextractor.py
+
+9. Make sure your code works under all Python versions claimed
+ supported by youtube-dl, namely 2.6, 2.7, and 3.2+.
+10. When the tests pass, add the new files and commit them and push the
result, like this:
$ git add youtube_dl/extractor/extractors.py
$ git commit -m '[yourextractor] Add new extractor'
$ git push origin yourextractor
-10. Finally, create a pull request. We'll then review and merge it.

In any case, thank you very much for your contributions!
This code will try to extract from meta first and if it fails it will
try extracting og:title from a webpage.
-Make regular expressions flexible
+Regular expressions
+
+Don't capture groups you don't use
+
+Capturing group must be an indication that it's used somewhere in the
+code. Any group that is not used must be non capturing.
+
+Example
+
+Don't capture id attribute name here since you can't use it for anything
+anyway.
+
+Correct:
-When using regular expressions try to write them fuzzy and flexible.
+ r'(?:id|ID)=(?P<id>\d+)'
+
+Incorrect:
+
+ r'(id|ID)=(?P<id>\d+)'
+
+Make regular expressions relaxed and flexible
+
+When using regular expressions try to write them fuzzy, relaxed and
+flexible, skipping insignificant parts that are more likely to change,
+allowing both single and double quotes for quoted values and so on.
Example
r'<span style="position: absolute; left: 910px; width: 90px; float: right; z-index: 9999;" class="title">(.*?)</span>',
webpage, 'title', group='title')
-Use safe conversion functions
+Long lines policy
+
+There is a soft limit to keep lines of code under 80 characters long.
+This means it should be respected if possible and if it does not make
+readability and code maintenance worse.
+
+For example, you should NEVER split long string literals like URLs or
+some other often copied entities over multiple lines to fit this limit:
+
+Correct:
+
+ 'https://www.youtube.com/watch?v=FqZTN594JQw&list=PLMYEtVRpaqY00V9W81Cwmzp6N6vZqfUKD4'
+
+Incorrect:
+
+ 'https://www.youtube.com/watch?v=FqZTN594JQw&list='
+ 'PLMYEtVRpaqY00V9W81Cwmzp6N6vZqfUKD4'
+
+Inline values
+
+Extracting variables is acceptable for reducing code duplication and
+improving readability of complex expressions. However, you should avoid
+extracting variables used only once and moving them to opposite parts of
+the extractor file, which makes reading the linear flow difficult.
+
+Example
+
+Correct:
+
+ title = self._html_search_regex(r'<title>([^<]+)</title>', webpage, 'title')
+
+Incorrect:
+
+ TITLE_RE = r'<title>([^<]+)</title>'
+ # ...some lines of code...
+ title = self._html_search_regex(TITLE_RE, webpage, 'title')
+
+Collapse fallbacks
+
+Multiple fallback values can quickly become unwieldy. Collapse multiple
+fallback values into a single expression via a list of patterns.
+
+Example
+
+Good:
+
+ description = self._html_search_meta(
+ ['og:description', 'description', 'twitter:description'],
+ webpage, 'description', default=None)
+
+Unwieldy:
+
+ description = (
+ self._og_search_description(webpage, default=None)
+ or self._html_search_meta('description', webpage, default=None)
+ or self._html_search_meta('twitter:description', webpage, default=None))
+
+Methods supporting list of patterns are: _search_regex,
+_html_search_regex, _og_search_property, _html_search_meta.
+
+Trailing parentheses
+
+Always move trailing parentheses after the last argument.
+
+Example
+
+Correct:
+
+ lambda x: x['ResultSet']['Result'][0]['VideoUrlSet']['VideoUrl'],
+ list)
+
+Incorrect:
+
+ lambda x: x['ResultSet']['Result'][0]['VideoUrlSet']['VideoUrl'],
+ list,
+ )
+
+Use convenience conversion and parsing functions
+
+Wrap all extracted numeric data into safe functions from
+youtube_dl/utils.py: int_or_none, float_or_none. Use them for string to
+number conversions as well.
+
+Use url_or_none for safe URL processing.
+
+Use try_get for safe metadata extraction from parsed JSON.
+
+Use unified_strdate for uniform upload_date or any YYYYMMDD meta field
+extraction, unified_timestamp for uniform timestamp extraction,
+parse_filesize for filesize extraction, parse_count for count meta
+fields extraction, parse_resolution, parse_duration for duration
+extraction, parse_age_limit for age_limit extraction.
+
+Explore youtube_dl/utils.py for more useful convenience functions.
+
+More examples
+
+Safely extract optional description from parsed JSON
+
+ description = try_get(response, lambda x: x['result']['video'][0]['summary'], compat_str)
+
+Safely extract more optional metadata
-Wrap all extracted numeric data into safe functions from utils:
-int_or_none, float_or_none. Use them for string to number conversions as
-well.
+ video = try_get(response, lambda x: x['result']['video'][0], dict) or {}
+ description = video.get('summary')
+ duration = float_or_none(video.get('durationMs'), scale=1000)
+ view_count = int_or_none(video.get('views'))
