How is the mobile WEB live broadcast in 6 rooms realized?

how is the mobile WEB live broadcast in 6 rooms realized? Unlike other platforms, he will display this video at the bottom and cannot be paused. Many elements can be covered on the video layer. He has tried many ways. It seems that as long as the video starts to play, it will no longer be able to send a bullet screen to this video. The video has the highest level, but the six-room one seems to be able to ask God for guidance.
