Description of your pull request and other information

Fixes issue #23010

The chaturbate extractor broke some time this evening. The regex looking for .m3u8 URLs no longer matched anything. Additionally, the URL now needs a bit of extra processing.

The page source contains a large JavaScript string containing an encoded JSON object. The nested quotes, as well as other special characters, are encoded as e.g. \u0022. So, we match the URL delimited by \u0022 or \u0027 (double or single quotes, respectively) and then decode any \uXXXX sequences in the match group.

Noob here, how do I implement these changes?

@Ubernoob7 Here's one way to do it:

1. Download my fork: https://github.com/throwaway396/youtube-dl/archive/master.zip
2. Extract it somewhere convenient
3. Open a terminal (command prompt) in the youtube-dl-master folder you just extracted
4. Run python youtube_dl/__main__.py "https://chaturbate.com/model/"

I'm assuming you already have Python installed and in your PATH.

A simple interim fix: inserting a cookie "cb_legacy=1" reverts to the old behaviour.

Question for you, I have a crontab and a run-one system to automagiclly record streams when they go live, or come back from one of the private modes. The script it as follows "run-one youtube-dl -o '/home/ubuntu/video/%(title)s.%(ext)s' https://chaturbate.com/URL/"

How would I take your branch that i've installed and make it run from anyfolder when "youtube-dl" is called?

@pcjamesy Install it globally.

git clone https://github.com/throwaway396/youtube-dl /tmp/youtube-dl
cd /tmp/youtube-dl 
python3 setup.py install
