pytube.exceptions.RegexMatchError: regex pattern

See original GitHub issue

While the downloads work fine for many videos it fails on some like this video:

https://www.youtube.com/watch?v=tOMPGQP1G8o

the error is :

File "/usr/local/lib/python2.7/dist-packages/pytube/cipher.py", line 252, in get_signature
    tplan = get_transform_plan(js)
  File "/usr/local/lib/python2.7/dist-packages/pytube/cipher.py", line 71, in get_transform_plan
    name = re.escape(get_initial_function_name(js))
  File "/usr/local/lib/python2.7/dist-packages/pytube/cipher.py", line 47, in get_initial_function_name
    return regex_search(pattern, js, group=1)
  File "/usr/local/lib/python2.7/dist-packages/pytube/helpers.py", line 41, in regex_search
    .format(pattern=p),
pytube.exceptions.RegexMatchError: regex pattern (yt\.akamaized\.net/\)\s*\|\|\s*.*?\s*c\s*&&\s*d\.set\([^,]+\s*,\s*(?:encodeURIComponent\s*\()?(?P<sig>[a-zA-Z0-9$]+)\() had zero matches

Based on what @Elite posted, I changed cipher.py line 40 to:

r'.*?\s*c\s*&&\s*d|a\.set\([^,]+\s*,\s*(?:encodeURIComponent'

and line 43 to:

r'\bc\s*&&\s*d|a\.set\([^,]+\s*,\s*(?:encodeURIComponent'

and this resolved the problem for at least one video. No time to test properly and make a pull request right now, though.

Well … it is maintained. Just slowly.

If you try the latest version pip install git+https://github.com/nficano/pytube.git --upgrade, your video works for me
