Case Study of Illegal Video Streaming and Using You-Get for Video Download

Zhang and Sun from Jiangsu used their own servers and video‑parsing services to bypass protection on legitimate streaming platforms, obtaining playback links and illegally streaming over 83,000 titles through a self‑built app, generating 400 billion clicks and approximately 392 million CNY in ad revenue.

The court convicted them of copyright infringement, sentencing Zhang to 5 years 6 months and a 20 million CNY fine, and Sun to 3 years and a 4 million CNY fine.

The technical core of the case is video address parsing, which is not highly complex but can cause serious legal issues when misused.

Many open‑source projects, such as you‑get , can perform video parsing and downloading; the project has nearly 50 k stars.

To download a video with you‑get, simply paste the video URL:
