Sync multiple HLS videos in single player in Javascript / React

looking to build a sync engine in java script for multiple HLS videos. The player should allow the user to switch between 5 videos with no break in the audio. Each video is a camera from the same event and has the same audio embedded. In addition each camera has a dat time tag in the manifest which can be used to align the sync.

Open to discuss options with potential contractors

Deliverables
A sync engine built in JS capable of switching 5 videos in real time with no break in the audio.

Player to handle the sync built in React.
