The main update is the fix of the no watermark method.
The naming scheme for that method has changed it is now get_video_no_watermark(self, video_url, return_bytes=1, **kwargs)
The other change is the introduction of get_tiktok_by_html(self, url, **kwargs) this was added a helper method of get_video_no_watermark but it extracts the information from the HTML of a TikTok rather than API calls
To download a video here's example code
from TikTokApi import TikTokApi
api = TikTokApi.get_instance(use_test_endpoints=True)
data = api.get_video_no_watermark('https://www.tiktok.com/@gordonramsayofficial/video/6910298199769009414?lang=en')
with open("test.mp4", "wb") as out:
out.write(data)
