描述

The YouTube player allows to go "back in time" in a live video up to 12 hours, and if you pause the video at -12h and return after some time, you can still play it, so it should be possible to download the video even more than 12 hours back.

However, using ytdl-core, I could only download live videos up to 4 hours back, which was the previous limit.

研究方向
Investigate the ytdl core source code, particularly the live stream handling in files like lib/info.js and lib/format utils.js. Look for parameters that limit the time window for live video downloads, such as 'begin' or 'live chunked time'. The YouTube player allows up to 12 hours, so find how to extend the current 4 hour limit. Consult the YouTube API documentation for live stream URL parameters if needed.
