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

that case, simply report a bug.

+See item 6 of new extractor tutorial for how to run extractor specific

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):

will then be named TestDownload.test_YourExtractor,

- TestDownload.test_YourExtractor_2, etc.

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+.

-Make regular expressions flexible
+Regular expressions
-When using regular expressions try to write them fuzzy and flexible.
+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

+
+Correct:
