[Feature]Cache mode optimization #572

Is your feature request related to a problem? Please describe.
After I set the cache size to 256mb, it stops playing once it reaches 256mb. What I expect is that after playing 256mb of video cache, it would continue caching the next 256mb of video, like continuous caching.
Describe the solution you'd like
When caching, choose the cache duration or how many GB to cache. But if you keep caching until it reaches a specific size, it can easily wear out your hard drive, so it's better to cache this way. For example, set the cache to 30 minutes or 500GB. Then, once you've played 30 minutes or 500MB, the cache function will be triggered again, instead of continuously caching the entire video.
Describe alternatives you've considered
Set the cache to a certain number of MB, and after it reaches that size, keep caching continuously while playing.
