Current version not support [beeg.porn], such as:
https://beeg.porn/video/8715192/japanese-schoolgirl-being-groped

Actually, beeg.py has supported it.
beeg.py, line 12, please modify
_VALID_URL = r'https?://(?:www\.)?beeg\.com/(?P<id>\d+)'
to
_VALID_URL = r'https?://(?:www\.)?beeg\.(?:com|porn)/(?:video/)?(?P<id>\d+)'
I has tested it. It works fine
