问题
I have a YouTube Live Event. I am able to play the video using the YouTube IFrame Player API. I want to know if there is any way that I can find if the video is a Live event video or a regular uploaded video. I need this information for designing my controls.
回答1:
The only way you can do this (currently) is with youtube backend api.
Get data about the video based on its id and in the response you have a property snippet.liveBroadcastContent which is either live, none, or upcoming.
回答2:
The IFrame API provides a Playback quality function which returns a string representation of the current video quality.
From my tests, this function will return an undocumented string auto for live events.
