API

detectAutoplay()

detectAutoplay(timeout?: number): Promise<boolean>

Detect if the current website is allowed to autoplay audio and video. If autoplay is allowed, the detection result will be cached, and the next time this function is called, will directly return true.

The parameter timeout is the detection timeout, will return false if it timeout. default is 300ms

forceDetectAutoplay()

forceDetectAutoplay(timeout?: number): Promise<boolean>

Same as detectAutoplay, but it doesn't cache the result, it re-detect every time.
